Memmert wall bracket B29756 for size 55

The Memmert IF55 incubator has a capacity of 53 litres and, with up to four shelves and a maximum total load of 80 kg, is designed to accommodate several samples running simultaneously. The temperature range, with forced air circulation, is from +20 to +80 °C; an electropolished stainless steel grid shelf is included as part of the scope of delivery.Interior and air circulationInside, the IF55 features deep-drawn ribbing and is heated all round; the housing has a fully galvanised sheet steel rear panel. Air circulation is provided by a low-noise turbine, the speed of which can be adjusted in 10 % increments.Operation and measurement technologyThe SingleDISPLAY-ControlCOCKPIT, featuring a TFT colour graphics display, allows the temperature to be set in either Celsius or Fahrenheit, as well as the speed of the recirculation fan, the position of the exhaust air damper, and the programme duration, time zones and summer/winter time. The temperature is measured by a DIN Class A Pt100 sensor using a 4-wire measurement method; the setting accuracy is 0.1 °C. A self-diagnostic system reports faults, whilst the data logger can be read out and managed via the Ethernet interface.Safety and lockingA mechanical temperature limiter, protection class 1 according to DIN 12880, switches off the heating when the temperature rises to around 20 °C above the maximum cabinet temperature. The fully insulated stainless steel door with an internal glass door is secured by a 2-point locking mechanism acting as a compression door lock.Which size is right for me?Memmert supplies the IF55 with one shelf as standard; up to four are possible, with a maximum load of 80 kg for the unit and 20 kg per shelf. Whilst this is more than sufficient for smaller sample quantities, the IF30, with a capacity of 32 litres, offers a more compact alternative. Those who regularly incubate larger batches will find the IF75, with a 74-litre capacity and up to six shelves, offers greater capacity.Typical applicationsWith an internal volume of 53 litres, the IF55 is suitable as an incubator for incubating and temperature-controlling medium-sized sample quantities in research, medicine, pharmaceuticals, food analysis and food chemistry.Incubating multiple samples simultaneously in research and medicineTemperature control of sample series in the pharmaceutical industryStandard incubation procedures in food analysis and food chemistryTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangeat least 10 °C above room temperature up to +80 °CTemperature setting accuracy0.1 °CTemperature sensor1x Pt100, DIN Class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of the housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kgConnection 230 V50/60 Hz, approx. 1,000 WConnection 115 V (optional)50/60 Hz, approx. 900 WMaximum number of shelves4Shelves included in the scope of delivery1Max. load on the unit80 kgMax. load per shelf20 kgInteriordeep-drawn ribbed, 4-sided all-round heatingControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayPermissible ambient temperature+5 °C to +40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMaximum installation altitude2,000 mMarkingsCE, VDE GS, ULOther sizes in the seriesWithin the IF range featuring SingleDISPLAY, the internal volume ranges from 32 to 749 litres; the models are listed here by size:ModelInternal volumeSetting temperatureDisplayIF3032 l+20 to +80 °CSingleDISPLAYIF55 (this page)53 l+20 to +80 °CSingleDISPLAYIF7574 l+20 to +80 °CSingleDISPLAYIF110108 l+20 to +80 °CSingleDISPLAYIF160161 l+20 to +80 °CSingleDISPLAYIF260256 l+20 to +80 °CSingleDISPLAYIF450449 l+20 to +80 °CSingleDISPLAYIF750749 l+20 to +80 °CSingleDISPLAYThe IF-plus series includes the IF55plus, which has the same internal volume and features TwinDISPLAY and two Pt100 sensors that monitor each other and take over the function in the event of a fault.Scope of deliveryFactory calibration certificate (at +37 °C)Fully insulated stainless steel door with a 2-point locking system (compression door lock) and an internal glass door, single-leaf1 stainless steel grid shelf, electropolishedRegulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG). The WEEE registration number of the manufacturer, Memmert GmbH + Co. KG, is DE 66812464. Information on returning old appliances can be found on our Environment and Disposal page.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit. It covers the gap between the unit and the wall opening with stainless steel and is available with air slots (B29730) or without air slots (B29731). According to Memmert, the installation situation must be clarified technically beforehand. The flush-fit unit is therefore available on request through our procurement service.Individual requirements and procurement serviceThe IF55 can be ordered ex-works with, amongst other things, a 115 V power supply, a safety lock and special cable and conduit feed-throughs. Accessories available include additional drip trays, a stacking kit and an AtmoCONTROL licence. We arrange calibration, IQ/OQ/PQ and maintenance services for qualification and maintenance. We are happy to advise you personally on individual requirements or any questions regarding the appropriate equipment.

With an internal volume of 53 litres, the Memmert IN55 incubator offers significantly more capacity than the compact IN30, whilst retaining the same natural convection and the same temperature range of +20 to +80 °C. For laboratories that need to incubate more culture dishes, test tubes or sample containers simultaneously, for example in food analysis with larger sample batches or in routine microbiological work with several parallel runs, the IN55 offers more space, with gentle heat distribution and no forced air circulation.Natural convection for more culture vesselsThe Memmert IN55 incubator also operates without an air turbine or a forced air circulation motor. Heat rises within the chamber purely by convection; there is no forced air movement. The working temperature range starts at a minimum of 5 °C above room temperature and extends up to 80 °C. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration ensures a setting accuracy of 0.1 °C across the entire working range.ControlCOCKPIT SingleDISPLAY and data acquisitionThe IN55 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphics display. You can set the temperature in Celsius or Fahrenheit, as well as the position of the exhaust air flap, the programme duration, the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWAIT function only starts the incubation time once the setpoint temperature has been reached, ensuring comparable incubation conditions when several batches are running in parallel. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert IN55 incubatorThe interior measures 400 x 400 x 330 mm, whilst the external dimensions are 585 x 784 x 514 mm. An electropolished stainless steel grid shelf is included in the scope of delivery; the cabinet can accommodate up to four shelves in total, one more than the IN30. The maximum load capacity is 80 kg for the entire unit and 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The IN55 is connected to a 230 V (approx. 1,000 W) or 115 V (approx. 900 W) supply, in each case at 50/60 Hz.Choosing the right size of incubatorIn addition to the two natural convection models, the IN30 and IN55, there is also the IF30plus, a forced air circulation variant featuring TwinDISPLAY, which is a factor to consider when making a selection, depending on requirements for temperature distribution and chamber hygiene.ModelInternal volume and controlIN3032 l, natural convection, SingleDISPLAY, max. 3 shelvesIN5553 l, natural convection, SingleDISPLAY, 4 shelves max.IF30plus32 l, forced air circulation, TwinDISPLAY, 3 shelves max.If the capacity of the Memmert IN30 incubator at 32 litres is no longer enough, the IN55, with a capacity of 53 litres and an additional shelf, is the obvious next step, whilst taking up only slightly more floor space. Those who require active air circulation and an integrated sterilisation programme will find these features in the Memmert IF30plus incubator. The full range can be found at Climate chambers & incubators.Difference between incubator and heating oven, IN and IFUnlike the UN55, a universal oven of the same size, the IN55 is designed for incubation temperatures of up to 80 °C and comes fitted as standard with an internal glass door, allowing visual inspection without opening the outer door. Within the incubator range, the key purchasing decision remains whether to opt for natural convection (IN series) or forced air circulation (IF series): The forced-air variant, the IF30plus, features an air turbine, two Pt100 sensors for mutual monitoring, TwinDISPLAY and an integrated sterilisation programme, albeit with a smaller internal volume of 32 litres instead of 53 litres. Those wishing to combine the greater capacity of the IN55 with quiet incubation without forced air circulation should stick with the IN series; those who switch between sample types and wish to clean the interior thermally from time to time should consider the IF30plus.Safety according to DIN 12880The IN55 features adjustable electronic temperature monitoring and a mechanical temperature limiter (protection class 1 according to DIN 12880), which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL test mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a minimum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side in relation to the wall or an adjacent unit. The unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 %, non-condensing. Electrically, the IN55 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the IN55 is subject to the German Electrical and Electronic Equipment Act (ElektroG) at the end of its service life and must not be disposed of with household waste.Typical applicationsWith an internal volume of 53 litres and up to four shelves, the Memmert IN55 incubator is suitable for microbiological and food technology applications involving a higher sample throughput than the compact IN30.Incubation of several parallel series of culture media in routine microbiological testingBacterial count analysis and shelf-life testing for large volumes of samplesIncubation in pharmaceutical applications and research, with several batches running simultaneouslyVisual inspection of running cultures without any loss of temperature, thanks to the internal glass doorEquipment for higher sample throughputThe scope of delivery for the IN55 includes 1 electropolished stainless steel grid shelf and the inner glass door; the cabinet is designed to accommodate up to 4 shelves. If you regularly use all the levels, you should order additional grid shelves accordingly. For process documentation, a permanent AtmoCONTROL software licence is recommended instead of the time-limited trial version, supplemented by a USB-to-Ethernet adapter. If you wish to secure access, you can configure a lockable door with a security lock; for enhanced safety, an additional Pt100 sensor with over-temperature protection is available. For pharmaceutical or standards-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including DAkkS calibration on request. For confined spaces, a stacking kit is also available, allowing two incubators of the same size to be stacked on top of one another to save space.Frequently asked questions before making a purchaseHow does the IN55 differ from the smaller IN30?Both operate using natural convection and feature the same ControlCOCKPIT SingleDISPLAY; the IN55 offers greater capacity, 53 litres instead of 32, and 4 shelves instead of 3, whilst taking up only slightly more floor space.What is the purpose of the inner glass door?It allows you to visually inspect the cultures without having to open the fully insulated outer door, which reduces temperature fluctuations inside the chamber.How many samples can fit into the IN55 at the same time?One grid shelf is included as standard; up to four shelves, each with a maximum load of 20 kg, can be fitted, giving a total load capacity of up to 80 kg.Up to what temperature does the IN55 operate?The setting temperature range is from +20 to +80 °C; the working temperature range starts at a minimum of 5 °C above room temperature.Is the IN55 a medical device?No, the IN55 is not a medical device; this applies only to the separate m and mplus variants.Is there a version with active air circulation?Yes, the Memmert IF30plus incubator features forced air circulation, TwinDISPLAY and an integrated sterilisation programme, although its capacity is 32 litres rather than 53 litres.Is the IN55 suitable for continuous operation over several days?The mechanical temperature limiter of protection class 1 according to DIN 12880 switches the heater off when the temperature rises by approximately 20 °C. Information on continuous operation is available on request.Can I stack several IN55 units on top of one another?A stacking kit allows several units to be stacked on top of one another to save space, provided the surface can safely support the additional load.How loud is the IN55 when in operation?A separate sound pressure level is not specified. As the IN55 operates without an air turbine, there is at least no fan noise, which is audible with forced air circulation units such as the IF30plus are in operation.Technical detailsSetting temperature range+20 to +80 °CWorking temperature rangeat least 5 °C above room temperature up to 80 °CTemperature setting accuracy0.1 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of the housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kg230 V connection50/60 Hz, approx. 1,000 W115 V connection50/60 Hz, approx. 900 WMaximum number of shelves4Shelves included in the scope of delivery1Max. load on the unit80 kgMaximum load per shelf20 kgInterior materialsStainless steel, 4-sided all-round heatingHousing materialTextured stainless steel, galvanised sheet steel rear panelRegulationControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayTimer1 minute to 99 days, digital countdown clockPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMaximum installation altitude2,000 mLabellingCE, EAC, UL test markScope of delivery1x Memmert IN55 incubatorFactory calibration certificate (calibrated at 37 °C)Fully insulated stainless steel door with a 2-point locking system (compression door lock)Inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThe Memmert IN55 incubator is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit.

Through our procurement service, we’d be happy to assist you with procurement and configuration.

The Memmert IF55plus incubator has an internal volume of 53 litres and, with external dimensions of 585 x 784 x 514 mm, is one of the more compact models in the range. The scope of delivery includes a stainless steel grid shelf and space for up to four shelves. It is suitable for smaller sample quantities where floor space is limited. The forced air circulation is generated by an air turbine and controlled via TwinDISPLAY using two Pt100 sensors.Interior and air flowThe interior measures 400 x 400 x 330 mm and is reinforced by deep-drawn ribbing; the heating elements are integrated and protected on all four sides. The air turbine is electronically controllable and can be adjusted in 10 % increments. Preheated fresh air is introduced via an electronically adjustable exhaust air damper; the exhaust air outlet with a throttle valve can also be controlled electronically. The permissible total load is 80 kg, with a maximum of 20 kg per shelf; the net weight of the cabinet is approximately 57 kg.Controls and safety featuresThe temperature setting range extends from +20 to +80 °C with a setting accuracy of 0.1 °C. Two mutually monitoring Pt100 sensors of DIN Class A automatically take over the function of the other in the event of a fault; control is via ControlCOCKPIT TwinDISPLAY with two TFT colour graphic displays. HeatBALANCE redistributes the heating power between the upper and lower heating groups by up to 50 % in either direction, whilst SetpointWAIT ensures that the process time only begins once the setpoint temperature has been reached. Additional safety is provided by AutoSAFETY: This function monitors the setpoint within a freely selectable tolerance and triggers a visual and audible alarm in the event of a deviation; a mechanical temperature limiter of protection class 1 according to DIN 12880 switches off independently of this at around 20 °C above the maximum cabinet temperature. On the display, users can choose to activate either an adjustable temperature monitor (protection class 3.1) or an adjustable temperature limiter (protection class 2); a self-diagnostic system assists with troubleshooting. Three temperature values can be freely calibrated; AtmoCONTROL manages programmes via Ethernet or USB; the permanently installed sterilisation programme sterilises the interior at 160 °C for 4 hours, but not the contents inside. Permitted operating conditions include an ambient temperature of +5 °C to +40 °C, a maximum relative humidity of 80 % (non-condensing) and an installation altitude of up to 2,000 m above sea level.Guide to choosing the right sizeFor those with even less floor space or who only incubate individual small samples, the size chart below shows the IF30plus (32 l) as the most compact model in the range. If you regularly require more capacity, the IF75plus offers more space with a 74-litre capacity and up to six shelves. It has the same width and depth of 585 x 514 mm, but at 944 mm is 160 mm taller.Typical applicationsAs a forced-air incubator, the IF55plus is designed for incubation and temperature-control processes and is used in research, medicine, pharmaceuticals, food analysis and food chemistry.Incubation and temperature control of smaller sample quantities in researchIncubation processes in medicine and pharmaceuticalsIncubation and temperature control of samples in food analysis and food chemistryTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangeat least 10 °C above room temperature up to +80 °CTemperature setting accuracy0.1 °CTemperature sensor2x Pt100, DIN Class A, 4-wire measurement, redundantInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kgConnection 230 V50/60 Hz, approx. 1,000 WConnection 115 V50/60 Hz, approx. 900 WMaximum number of shelves4Shelves included in the scope of delivery1Max. load on unit80 kgMax. load per shelf20 kgControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysAdditional functionsHeatBALANCE, SetpointWAIT, AutoSAFETY, visual and audible alarmPermissible ambient temperature+5 °C to +40 °CPermissible relative humiditymax. 80 % rel., non-condensingMaximum installation altitude2,000 mMarkingsCE, VDE GS, UL, EACOther sizes in the seriesThe IF-plus series comprises eight sizes ranging from 32 to 749 litres with TwinDISPLAY, listed below by internal volume:ModelInternal volumeSetting temperatureDisplayIF30plus32 l+20 to +80 °CTwinDISPLAYIF55plus (this page)53 l+20 to +80 °CTwinDISPLAYIF75plus74 l+20 to +80 °CTwinDISPLAYIF110plus108 l+20 to +80 °CTwinDISPLAYIF160plus161 l+20 to +80 °CTwinDISPLAYIF260plus256 l+20 to +80 °CTwinDISPLAYIF450plus449 l+20 to +80 °CTwinDISPLAYIF750plus749 l+20 to +80 °CTwinDISPLAYWe offer the same size with a temperature sensor and SingleDISPLAY instead of the two monitoring Pt100 sensors as the IF55.Scope of delivery1x Memmert IF55plus incubatorFactory calibration certificate (calibrated at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock)Inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

It covers the gap between the unit and the wall opening with stainless steel and is available with air slots (B29730) or without air slots (B29731). According to Memmert, the installation situation must be clarified technically beforehand. The flush-fit unit is therefore available on request through our procurement service.Individual requirements and procurement serviceFor the IF55plus, the following items, amongst others, can be ordered ex-works: interior lighting, temperature throttling (factory limit on the maximum adjustable temperature), door-open detection and a lockable door. Available accessories include an additional perforated stainless steel tray, a slide-in drip tray, a wall bracket, a stacking kit and a levelling or mobile base frame. For calibration and qualification, we arrange DAkkS calibrations as well as IQ/OQ/PQ documentation. We are happy to advise you personally on any individual requirements.

The IN55plus has a capacity of 53 litres and, unlike the smaller IN30plus, also features the HeatBALANCE function for fine-tuning the distribution of heating power. Two Pt100 sensors monitor each other, whilst control is managed via a ControlCOCKPIT TwinDISPLAY within the range of +20 to +80 °C.Design and air flowNatural convection mixes in preheated fresh air via an electronically adjustable exhaust air flap; the exhaust air outlet with throttle valve is electronically controllable. The interior is reinforced with deep-drawn ribbing and features a protected, integrated 4-sided all-round heating system. Those requiring forced air circulation instead of natural convection will find the same size in the IF-plus series.Control via the ControlCOCKPIT TwinDISPLAYHeatBALANCE adjusts the distribution of heating output between the upper and lower heating groups from -50 to +50 %, controlled via the ControlCOCKPIT TwinDISPLAY with two TFT colour graphic displays and two DIN Class A Pt100 sensors in a 4-wire measurement configuration. Programmes are managed via Ethernet or USB using AtmoCONTROL; the setting accuracy is 0.1 °C.Safety and sterilisation programmeA mechanical temperature limiter of protection class 1 according to DIN 12880 forms the first level of protection and switches off at approximately 20 °C above the maximum cabinet temperature. Additionally, an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2 can be selected; AutoSAFETY signals deviations from the setpoint visually and acoustically. A permanently installed sterilisation programme (4 hours at 160 °C) sterilises the interior of the cabinet, not the contents.Selection guide for the right sizeIf the 32-litre IN30plus is no longer sufficient, the 53-litre IN55plus offers more capacity and the additional HeatBALANCE feature. If even more space is required, the 74-litre IN75plus is the next option in the size chart below.Typical applicationsWith a 53-litre capacity, the IN55plus is suitable for incubating and temperature-controlling samples in the range from +20 to +80 °C, including in research applications.Incubation and temperature control with redundant sensor monitoringInternal chamber sterilisation via the permanently installed sterilisation programmeUse in researchTechnical detailsTemperature setting range+20 to +80 °COperating temperature rangeAt least 5 °C above room temperature up to +80 °CTemperature setting accuracy0.1 °CTemperature sensor2 Pt100 sensors, DIN Class A, in a 4-wire configuration for mutual monitoring and automatic failover in the event of a faultHeatBALANCE functionAdjustment of the heating power distribution between the upper and lower heating groups from -50 % to +50 %Adjustable temperature monitor/limiterAdjustable temperature monitor (TWW), protection class 3.1, or adjustable temperature limiter (TWB), protection class 2, selectable via the displayAutoSAFETYadditionally integrated over- and under-temperature monitoring ‘ASF’, automatically tracks the setpoint at a freely selectable interval, alarm if the temperature exceeds or falls below the setpoint, heating shut-off if the setpoint is exceededSterilisation programmePermanently installed sterilisation programme (4 hours/160 °C) for sterilising the interior; not intended for sterilising the loadInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of housing (W x H x D)585 x 784 x 514 mm (depth plus 56 mm for door handle)Net weightapprox. 57 kgConnection 230 V50/60 Hz, approx. 1,000 WConnection 115 V50/60 Hz, approx. 900 WMaximum number of shelves4Shelves in scope of delivery1InteriorEasy to clean, reinforced with deep-drawn ribbing, with protected, integrated 4-sided all-round heatingControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysPermissible ambient temperature+5 °C to +40 °CPermissible relative humiditymax. 80 % non-condensingMaximum installation heightmax. 2,000 m above sea levelMarkingsCE, VDE GS, UL, EACOther sizes in the seriesThe IN-plus series with TwinDISPLAY ranges from 32 to 749 litres internal volume, sorted by internal volume:ModelInternal volumeSet temperatureDisplayIN30plus32 l+20 to +80 °CTwinDISPLAYIN55plus (this page)53 l+20 to +80 °CTwinDISPLAYIN75plus74 l+20 to +80 °CTwinDISPLAYIN110plus108 l+20 to +80 °CTwinDISPLAYIN160plus161 l+20 to +80 °CTwinDISPLAYIN260plus256 l+20 to +80 °CTwinDISPLAYIN450plus449 l+20 to +80 °CTwinDISPLAYIN750plus749 l+20 to +80 °CTwinDISPLAYThe same capacity is also available with SingleDISPLAY and a Pt100 sensor in the IN series: IN55.Scope of delivery1x Memmert IN55plus incubatorFactory calibration certificate (calibrated at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock)Inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The Memmert incubator IF55m has 53 litres internal volume with an internal width of 400 mm, as wide as the IF30m. Like all IF-m models, it is a Class I medical device under Regulation (EU) 2017/745 with the intended purpose of warming and keeping warm of fango, silicate and APS packs in physiotherapy. Compared with the smaller IF30m, the internal height (320 to 400 mm) and internal depth (250 to 330 mm) each grow by 80 mm, and up to four shelves fit in instead of three.Construction and loadingThe internal dimensions of 400 x 400 x 330 mm are in an easy-care, deep-drawn ribbed stainless steel interior with integrated 4-sided all-round heating. One stainless steel grid shelf, electropolished, is part of the scope of delivery, and up to four can be inserted, each 20 kg per shelf, 80 kg in total. The stainless steel door is fully insulated and closes via a 2-point locking system, and the inner glass door keeps the view into the chamber open. Externally, the housing measures 585 x 784 x 514 mm, and the net weight is around 57 kg.Timer, calibration and data loggerThe IF55m is controlled via the ControlCOCKPIT SingleDISPLAY with adaptive PID controller and TFT colour graphic display, a Pt100 sensor of DIN class A measures using 4-wire technology, and the setting accuracy is 0.1 °C. The digital countdown timer with target time display can be set from 1 minute to 99 days, and SetpointWAIT only counts the process time once the setpoint temperature has been reached. Three temperature values can be freely calibrated. The data logger is read out via an Ethernet interface, the AtmoCONTROL software is available for this as a time-limited trial version, and it can be obtained permanently as an accessory.Temperature monitoringThe mechanical temperature limiter of protection class 1 according to DIN 12880 switches the heating off at around 20 °C above the maximum cabinet temperature. In addition, an adjustable electronic monitoring system runs alongside, and a self-diagnosis system helps with troubleshooting.Distinction from IN-m and IF-mplusWithout forced air circulation, but with the same chamber size and the same intended purpose, the IN55m is available, an incubator with natural convection. The IF55mplus shares the 53 litres, but has a different intended purpose (warming of irrigation and infusion solutions and contrast media) and a TwinDISPLAY with two displays instead of the single SingleDISPLAY.Selection guide: suitable sizeIf up to three shelves and a maximum load of 60 kg are enough, the smaller IF30m with 32 litres and a lower, less deep housing (585 x 704 x 434 mm) is sufficient. If more than four grid shelves or more than 80 kg are regularly needed, the IF75m with 74 litres and 120 kg permissible total load is the more suitable step.Typical applicationsAs a Class I medical device, the Memmert incubator IF55m is intended exclusively for physiotherapeutic applications with fango, silicate and APS packs.Warming of fango packs for physiotherapeutic useWarming and keeping warm of silicate packsWarming and keeping warm of APS packsTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangeAt least 10 °C above room temperature to +80 °CTemperature setting accuracy0.1 °CTemperature sensor1x Pt100, DIN class A, 4-wire measurementControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of housing (W x H x D)585 x 784 x 514 mmShelves in scope of delivery1Maximum shelves4Max. load of unit80 kgMax. load per shelf20 kgConnection230 V, 50/60 Hz, approx. 1,000 W; 115 V, 50/60 Hz, approx. 900 WNet weightapprox. 57 kgMedical device classificationClass I under Regulation (EU) 2017/745Intended purposeWarming and keeping warm of fango, silicate and APS packs in physiotherapyPermissible ambient temperature+5 °C to +40 °CPermissible humiditymax. 80 % rh, non-condensingMarkingsCE, VDE, cULus ListedOther sizes in the seriesThe IF55m is one of eight sizes in the IF-m series from 32 to 749 litres, all with SingleDISPLAY and the same setting temperature range of +20 to +80 °C.ModelInternal volumeSetting temperatureDisplayIF30m32 l+20 to +80 °CSingleDISPLAYIF55m (this page)53 l+20 to +80 °CSingleDISPLAYIF75m74 l+20 to +80 °CSingleDISPLAYIF110m108 l+20 to +80 °CSingleDISPLAYIF160m161 l+20 to +80 °CSingleDISPLAYIF260m256 l+20 to +80 °CSingleDISPLAYIF450m449 l+20 to +80 °CSingleDISPLAYIF750m749 l+20 to +80 °CSingleDISPLAYScope of delivery1x Memmert incubator IF55mFactory calibration certificate (calibration at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock)Inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThe device is electrical equipment within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The Memmert incubator IN55m is a class I medical device according to Regulation (EU) 2017/745 with the intended purpose of warming and keeping warm fango, silicate and APS packs in physiotherapy. With 53 litres of internal volume and internal dimensions of 400 x 400 x 330 mm, it sits between the smaller IN30m and the larger IN75m. One electropolished stainless steel grid shelf is supplied as standard, and up to four shelves are possible.Control and sensorsThe temperature is controlled by the ControlCOCKPIT SingleDISPLAY: an adaptive, multifunctional PID microprocessor controller with a high-resolution digital TFT colour graphic display. Measurement is via a Pt100 sensor of DIN class A in 4-wire technology, and the setting accuracy is 0.1 °C. The digital countdown timer with target time display can be set from 1 minute to 99 days, and SetpointWAIT ensures that the process time begins to run only after the set temperature has been reached. Three freely selectable temperature values are available for calibration.Ventilation, safety and loggingPreheated fresh air enters the naturally ventilated interior via an electronically adjustable flap, and at the exhaust air outlet an electronically adjustable throttle valve regulates the outlet. At around 20 °C above the maximum permissible cabinet temperature, a mechanical temperature limiter of protection class 1 according to DIN 12880 takes effect and switches off the heating, and an electronic temperature monitor can also be set. A built-in self-diagnosis system detects faults. The program sequence remains saved in the event of a power failure. The data logger is read out via the Ethernet interface, and a time-limited trial version of AtmoCONTROL is available for download for this purpose. A USB stick with the software is available as an accessory.Interior, loading and connectionInside, the IN55m is lined with easy-care, deep-drawn ribbed stainless steel, and the heating is protected and runs all round on all four sides. One electropolished stainless steel grid shelf is included as standard, up to four shelves fit inside, and a total of 80 kg at 20 kg per shelf is permitted. The fully insulated stainless steel door is locked by 2-point locking with a compression door lock, and behind it is an inner glass door. The power connection is 230 V at approx. 1,000 W, and in the 115 V version approx. 900 W, in each case 50/60 Hz. Externally, the housing measures 585 x 784 x 514 mm plus 56 mm for the door handle, and the cabinet weighs around 57 kg net.Distinction: laboratory unit IN55 and medical device IN55mplusIf you do not need a medical intended purpose, there is the Memmert incubator IN55 in the same size. Also with 53 litres, there is the IN55mplus: it shows the values via a ControlCOCKPIT TwinDISPLAY instead of the SingleDISPLAY, and its intended purpose differs fundamentally from the IN55m. It is intended for warming irrigation and infusion solutions and contrast media, not for warming fango, silicate and APS packs.Selection guide: which size fitsThe smaller IN30m offers 32 litres, three shelves and 60 kg total load. If more space is needed, the IN75m with 74 litres, six shelves and 120 kg total load is one step above the IN55m.Typical applicationsAs a class I medical device, the IN55m is intended exclusively for the physiotherapeutic applications stated in the intended purpose.Warming of fango packs for physiotherapeutic useWarming and keeping warm of silicate packsWarming and keeping warm of APS packsTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangemin. 5 °C above room temperature to +80 °CTemperature setting accuracy0.1 °CTemperature sensor1x Pt100, DIN class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of housing (W x H x D)585 x 784 x 514 mm (plus 56 mm door handle)Net weightapprox. 57 kgConnection230 V, 50/60 Hz, approx. 1,000 W; 115 V, 50/60 Hz, approx. 900 WShelves in the scope of delivery1Maximum number of shelves4Max. load of unit80 kgMax. load per shelf20 kgControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayMedical device classificationClass I according to Regulation (EU) 2017/745Intended purposeWarming/keeping warm of fango, silicate and APS packs in physiotherapyPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % rel., non-condensingMarkingsCE, VDE, ULOther sizes in the seriesThe IN55m is one of eight sizes in the IN-m series from 32 to 749 litres, all with SingleDISPLAY and the same setting temperature range of +20 to +80 °C.ModelInternal volumeSetting temperatureDisplayIN30m32 l+20 to +80 °CSingleDISPLAYIN55m (this page)53 l+20 to +80 °CSingleDISPLAYIN75m74 l+20 to +80 °CSingleDISPLAYIN110m108 l+20 to +80 °CSingleDISPLAYIN160m161 l+20 to +80 °CSingleDISPLAYIN260m256 l+20 to +80 °CSingleDISPLAYIN450m449 l+20 to +80 °CSingleDISPLAYIN750m749 l+20 to +80 °CSingleDISPLAYScope of deliveryFactory calibration certificate (calibration at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock), inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThe unit is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The flush-fit unit is therefore available on request through our procurement service.Individual requirements and procurement serviceFor the IN55m, Memmert offers options, accessories and services, and options are specified at the factory when ordering. For individual requirements concerning the IN55m, such as additional accessories or spare parts, you can contact us. As factory options, Memmert also offers DAkkS calibration according to DKD-R 5-7, IQ/OQ documents and IQ/OQ qualification. We order these with the device on request.

The Memmert incubator IF55mplus is a Class I medical device under Regulation (EU) 2017/745, with the intended purpose of warming irrigation and infusion solutions and contrast media. The 53 litre chamber lies between the smallest and the middle model of the mplus series and is suitable for smaller quantities. A stainless steel grid shelf is included as standard, and up to four shelves are possible.Control, HeatBALANCE and program transferTwo mutually monitoring Pt100 sensors of DIN class A work in 4-wire measurement and, in the event of a fault, automatically take over the function of the other. The setting accuracy is 0.1 °C with a setting temperature range of +20 to +80 °C. The ControlCOCKPIT TwinDISPLAY with two TFT colour graphic displays controls the cabinet, and the HeatBALANCE function adjusts the heating power distribution between the upper and lower heating group in the range from -50 to +50 %. Via the Ethernet interface or USB port, programs can be created, managed and transferred with the AtmoCONTROL software, and the program sequence is stored in the event of a power failure. The SetpointWAIT function only starts the process time once the setpoint temperature has been reached, and three temperature values can be freely calibrated.Safety technologyThe mechanical temperature limiter of protection class 1 according to DIN 12880 switches the heating off at approx. 20 °C above the maximum cabinet temperature. In addition, an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2 can be selected on the display. The AutoSAFETY monitoring follows the setpoint at a freely selectable distance, reports deviations visually and audibly, and switches the heating off when exceeded. A self-diagnosis system helps with fault finding. A fully insulated stainless steel door with 2-point locking (compression door lock) and an inner glass door close the chamber, and the stainless steel interior is stiffened by deep-drawn ribbing and has protected, integrated 4-sided all-round heating. The permanently installed sterilisation program (4 h at 160 °C) is used for sterilising the interior and is not intended for sterilising the load.Ventilation, connection and dimensionsThe air turbine is electronically adjustable in 10 % steps and runs quietly, and preheated fresh air is admixed via the electronically adjustable exhaust air flap. The IF55mplus is operated with 230 V at approx. 1,000 W or with 115 V at approx. 900 W, each 50/60 Hz. The internal dimensions are 400 x 400 x 330 mm, the housing measures 585 x 784 x 514 mm externally, and the net weight is around 57 kg. A total of up to 80 kg and 20 kg per shelf may be loaded.Distinction from the SingleDISPLAY variant and the laboratory deviceThere is the IF55m as the SingleDISPLAY variant with only one Pt100 sensor, also a Class I medical device, but with a different intended purpose: warming and keeping warm of fango, silicate and APS packs in physiotherapy. The IF55mplus differs from it in the TwinDISPLAY, the two redundant sensors, HeatBALANCE, AutoSAFETY and the adjustable temperature monitor or limiter selectable on the display. Without a medical intended purpose, but with technically comparable equipment, the IF55plus is also available as a laboratory incubator of the same chamber size.Selection guide: smaller or larger chamberThose who can manage with less volume will find the smallest size in the series in the IF30mplus with 32 litres. If 53 litres are not enough, the IF75mplus with 74 litres and up to six shelves offers more capacity.Typical applicationsThe IF55mplus is intended, as a Class I medical device, for the following applications:Warming irrigation solutionsWarming infusion solutionsWarming contrast mediaTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangemin. 10 °C above room temperature to +80 °CTemperature setting accuracy0.1 °CTemperature sensor2x Pt100, DIN class A, 4-wire measurement, redundantInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kgConnection230 V, 50/60 Hz, approx. 1,000 W; 115 V, 50/60 Hz, approx. 900 WShelves in scope of delivery1Maximum shelves4Max. load of unit80 kgMax. load per shelf20 kgControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displayAdditional functionsHeatBALANCE, AutoSAFETY, SetpointWAIT, programming via AtmoCONTROL (Ethernet/USB)Medical device classificationClass I under Regulation (EU) 2017/745Intended purposeWarming of irrigation and infusion solutions and contrast mediaPermissible ambient temperature+5 °C to +40 °CPermissible humiditymax. 80 % rh, non-condensingMarkingsCE, VDE, cULusOther sizes in the seriesThe mplus series offers eight chamber sizes from 32 to 749 litres, each with TwinDISPLAY and the setting temperature range +20 to +80 °C.

The IF55mplus also carries the classification as a Class I medical device under Regulation (EU) 2017/745; the intended purpose includes warming irrigation and infusion solutions and contrast media.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit. It covers the gap between the unit and the wall opening with stainless steel and is available with air slots (B29730) or without air slots (B29731). According to Memmert, the installation situation must be clarified technically beforehand. The flush-fit unit is therefore available on request through our procurement service.Individual requirements and procurement serviceFor the IF55mplus, the 115 V voltage variant and temperature limiting (factory limit on the maximum adjustable temperature) are available as factory options. For accessories, we arrange grid shelves, perforated trays, drip trays for shelf or floor, a wall bracket, a stacking kit or a levelling or mobile base. For DAkkS calibration, IQ/OQ/PQ documentation and qualification or a maintenance contract, we arrange the right contact. Contact us for individual advice.

With 53 litres, the Memmert incubator IN55mplus offers slightly more internal space than the smallest model in the series and takes up to four shelves. It is a Class I medical device under Regulation (EU) 2017/745 and is used for warming irrigation and infusion solutions and contrast media. A stainless steel grid shelf is part of the standard scope of delivery.ControlCOCKPIT TwinDISPLAYTwo TFT colour graphic displays belong to the ControlCOCKPIT TwinDISPLAY, which controls the IN55mplus and is an adaptive digital PID microprocessor controller. The temperature is measured by two Pt100 sensors of DIN class A in 4-wire measurement, which monitor each other; if one fails, the intact sensor takes over the function of the other. The setting temperature range is between +20 and +80 °C with a setting accuracy of 0.1 °C, and the working temperature range starts at least 5 °C above room temperature.Monitoring and protectionThe heating switches off automatically at around 20 °C above the maximum permissible cabinet temperature; a mechanical temperature limiter of protection class 1 according to DIN 12880 is responsible for this. In addition, an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2 can be set on the display. AutoSAFETY monitors overshoots and undershoots at a freely selectable distance from the setpoint, reports them visually and audibly, and switches the heating off in the event of an overshoot. A self-diagnosis system supports fault finding, and a permanently installed program sterilises the interior (4 hours, 160 °C), not the load.Functions and data transferWith the HeatBALANCE function, the heating power can be shifted between the upper and lower heating group in the range from -50 to +50 %, and SetpointWAIT starts the process time at the point when the setpoint temperature is reached. Three temperature values can be freely calibrated, and the program sequence remains stored in the event of a power failure. An Ethernet connection and a USB port are available for creating, managing and transferring programs, used with the AtmoCONTROL software.Construction, loading and connected loadEasy-care stainless steel with deep-drawn ribbing and four-sided all-round heating forms the interior, and the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. Natural ventilation admixes preheated fresh air via an electronically adjustable flap, and an electronically adjustable throttle valve at the exhaust air port regulates the exhaust air. Internal: 400 x 400 x 330 mm, external: 585 x 784 x 514 mm (plus 56 mm door handle), net weight around 57 kg. A total load of 80 kg is permitted, with a maximum of 20 kg per shelf. Connection is made with 230 V (approx. 1,000 W) or 115 V (approx. 900 W), each 50/60 Hz.The IN55m comparedThe equally sized IN55m has a different intended purpose: warming and keeping warm of fango, silicate and APS packs in physiotherapy, also as a Class I medical device. Instead of the two TFT displays and the redundant sensor pairing of the IN55mplus, the IN55m is controlled via a SingleDISPLAY with a single Pt100 sensor.Selection guideFor smaller quantities, the Memmert incubator IN30mplus with 32 litres, up to three shelves and 60 kg total load is sufficient. Those who need more space will find it with the IN75mplus with 74 litres, two grid shelves as standard and up to six shelves at 120 kg total load.Typical applicationsThe IN55mplus is intended, as a class I medical device, for warming irrigation and infusion solutions and contrast media.Warming irrigation solutionsWarming infusion solutionsWarming contrast mediaTechnical detailsSetting temperature range+20 to +80 °CWorking temperature rangemin. 5 °C above room temperature to +80 °CTemperature setting accuracy0.1 °CTemperature sensor2x Pt100, DIN class A, 4-wire measurement, redundantInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of housing (W x H x D)585 x 784 x 514 mm (plus 56 mm door handle)Net weightapprox. 57 kgConnection230 V, 50/60 Hz, approx. 1,000 W; 115 V, 50/60 Hz, approx. 900 WShelves in scope of delivery1Maximum shelves4Max. load of unit80 kgMax. load per shelf20 kgControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displayAdditional functionsHeatBALANCE, SetpointWAIT, AutoSAFETY, visual and audible alarmMedical device classificationClass I under Regulation (EU) 2017/745Intended purposeWarming of irrigation and infusion solutions and contrast mediaPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % rh, non-condensingShipping carton (W x H x D)730 x 950 x 670 mmMarkingsCE, VDE, ULOther sizes in the seriesThe IN55mplus is one of eight sizes in the IN-mplus series from 32 to 749 litres, all with TwinDISPLAY and the same setting temperature range of +20 to +80 °C.ModelInternal volumeSetting temperatureDisplayIN30mplus32 l+20 to +80 °CTwinDISPLAYIN55mplus (this page)53 l+20 to +80 °CTwinDISPLAYIN75mplus74 l+20 to +80 °CTwinDISPLAYIN110mplus108 l+20 to +80 °CTwinDISPLAYIN160mplus161 l+20 to +80 °CTwinDISPLAYIN260mplus256 l+20 to +80 °CTwinDISPLAYIN450mplus449 l+20 to +80 °CTwinDISPLAYIN750mplus749 l+20 to +80 °CTwinDISPLAYScope of deliveryFactory calibration certificate (calibration at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock), inner glass door1x stainless steel grid shelf, electropolishedRegulatory informationThe device is electrical equipment within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The Memmert universal oven UF55 is the smallest model in the forced-air series: 53 litres’ internal volume with a compact footprint, a temperature range of 20 to 300 °C and an electronically controlled air turbine that ensures active, uniform heat distribution even in a unit of this size. For laboratories wishing to switch from a natural convection unit to shorter heating times without taking up more floor space, the UF55 is the obvious entry-level choice for the series’ forced-air technology. With up to 4 shelves and a maximum total load capacity of 80 kg, it is a compact workhorse for routine tasks.Forced air circulation in the smallest of spaces: shorter heating timesThe UF55’s air turbine, which can be electronically controlled in 10 % increments, actively distributes heat throughout the interior, rather than simply allowing it to rise, as is the case with a natural convection cabinet. As a result, the UF55 achieves its operating temperature range from at least 10 °C above room temperature up to 300 °C, with shorter heating-up times than a comparable natural convection model such as the UN55, which, by contrast, starts operating from just 5 °C above room temperature and requires no air movement within the chamber. A DIN Class A Pt100 temperature sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards.ControlCOCKPIT SingleDISPLAY and data acquisitionThe UF55 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphics display. The following parameters can be adjusted: temperature in Celsius or Fahrenheit, the speed of the recirculation fan, the position of the exhaust air damper, the programme duration, as well as the time zone and summer/winter time. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWAIT function only starts the process time once the setpoint temperature has actually been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert universal oven UF55The interior measures 400 x 400 x 330 mm; the external dimensions of the cabinet are 585 x 784 x 514 mm, and the net weight is approximately 57 kg. One electropolished stainless steel grid shelf is included as standard; up to four shelves are possible in total. The maximum total load is 80 kg, with up to 20 kg permitted per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF55 can be connected either to 230 V (approx. 2,000 W) or 115 V (approx. 1,700 W), in both cases at 50/60 Hz.Selection guide: choosing the right size from the UF rangeThe Memmert UF range offers a choice of eight sizes, with internal volumes ranging from 53 to 1,060 litres. When making a selection, the footprint and the number of shelves required are often more important than the volume alone.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesThe UF55 is the entry-level model in this range. If you need more shelves whilst maintaining the same footprint, you’ll find them in the Memmert universal oven UF75 (74 litres, 6 shelves instead of 4, same footprint, just taller). You can find all sizes of the series in our climate chambers & incubators range.Distinction: Forced air circulation versus natural convection, and TwinDISPLAYWithin the Memmert family of heating and drying ovens, the most important purchasing decision is between forced air circulation (UF series) and natural convection (UN series). Thanks to its air turbine, the UF55 achieves shorter heating times, but its working temperature range only starts at 10 °C above room temperature, rather than at 5 °C like the Memmert universal oven UN55. For samples sensitive to dust or air movement, natural convection remains the more suitable choice. For unattended runs with redundant temperature monitoring, the Memmert universal oven UF55plus is available, featuring TwinDISPLAY, two Pt100 sensors, HeatBALANCE and AutoSAFETY. Those requiring greater capacity whilst maintaining the same footprint will find it in the Memmert universal oven UF75.Safety according to DIN 12880 for unattended operationIn addition to the adjustable electronic temperature monitoring, the UF55 is fitted with a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature rises to approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a minimum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side in relation to the wall or an adjacent unit. The unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 %, non-condensing. Electrically, the UF55 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning agents. As an electrical appliance, the UF55 is subject to the German Electrical and Electronic Equipment Act (ElektroG) at the end of its service life and must not be disposed of with household waste; see Regulatory information below.Typical applicationsWith an internal volume of 53 litres and active air circulation, the Memmert universal oven UF55 is suitable for compact laboratory workstations that still wish to benefit from shorter heating times.Drying of laboratory glassware and small batches of samples in routine operationsTempering, ageing and baking of material samplesTesting and curing in quality assuranceSample preparation within a tight timeframe thanks to a shorter heating timeAn entry-level unit for laboratories switching from natural convection to forced-air circulationInvestment rationale: Equipment tailored to the specific purposeThe scope of delivery for the UF55 includes 1 electropolished stainless steel grid shelf; the oven is designed to accommodate up to 4 shelves. Those who regularly run several batches in parallel should order additional grid shelves or perforated trays. A fully transparent glass door is available as an option for visual inspection without opening the door, as are interior lighting and an internal power socket for additional measurement equipment. Those wishing to use the data logger on a permanent basis should add an AtmoCONTROL software licence. For those wishing to run unattended cycles with redundant temperature monitoring, the Memmert universal oven UF55plus with TwinDISPLAY is worth choosing outright, rather than retrofitting accessories to the SingleDISPLAY model. For pharmaceutical or standards-based applications, calibration, IQ/OQ/PQ and maintenance services are available, including DAkkS calibration on request.Frequently asked questions before making a purchaseHow many samples can the UF55 hold at any one time?One grid shelf is included as standard; up to four shelves, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 80 kg.Can I place the UF55 on a laboratory bench?Yes, with a net weight of around 57 kg and a footprint of 585 x 514 mm, the UF55 is designed for use on a laboratory bench, provided that the bench can safely support the load.What is the difference between this model and the UN55?Both share the same casing and footprint. The UF55 actively distributes heat via an air turbine and heats up more quickly, whereas the Memmert universal oven UN55 operates with minimal vibration and dust, using natural convection.What is the accuracy of the temperature control?The UF55 achieves a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, measured using a DIN Class A Pt100 sensor in a 4-wire configuration.Can a glass door be fitted as a retrofit?A fully transparent glass door is one of the common options for the UF55 and can be selected when placing your order.How does the UF55 differ from the larger UF75?Both use the same forced air circulation technology and SingleDISPLAY; the UF75 offers greater capacity, 74 litres instead of 53, and 6 shelves instead of 4, whilst occupying the same floor space.Is the UF55 suitable for continuous overnight operation?The mechanical temperature limiter, of protection class 1 according to DIN 12880 switches the heater off when the temperature rises by approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °CWorking temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of the housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kg230 V connection50/60 Hz, approx. 2,000 W115 V connection50/60 Hz, approx. 1,700 WShelves max.4Shelves included in the scope of delivery1Max. load on the unit80 kgMax. load per shelf20 kgInterior materialsStainless steel, 4-sided all-round heatingHousing materialTextured stainless steel, galvanised sheet steel rear panelControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayTimer1 minute to 99 days, digital countdown clockPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMax. installation altitude2,000 mLabellingCE, EAC, UL marksScope of delivery1x Memmert universal oven UF55Factory calibration certificate (calibration at 160 °C)Fully insulated stainless steel door with a 2-point locking system (compression door lock)1x stainless steel grid shelf, electropolishedRegulatory informationThe Memmert universal oven UF55 is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit.

For those who have outgrown the Memmert universal oven UN30 but do not yet wish to install a floor-standing cabinet, the Memmert universal oven UN55 is the obvious next size up: 53 litres’ internal volume with almost the same footprint, and still utilising natural convection rather than an active air turbine. The temperature range extends from 20 to 300 °C, and the housing is made of textured stainless steel. As there is no active air circulation inside the chamber, the UN55 remains the first choice where vibration-free operation and low dust levels are more important than a particularly short heating time, for example, when drying samples laid out in the open or fine powders in slightly larger quantities than with the UN30.Natural convection: greater volume, same operating principleLike the smaller UN30 model, the Memmert UN55 universal oven deliberately does not feature an air turbine or a recirculation fan. Heat rises within the chamber purely by convection, without a fan stirring up dust or light sample particles. Consequently, the working temperature range starts from at least 5 °C above room temperature up to 300 °C, whilst the forced-air models of the UF series only start from 10 °C above room temperature, but heat up more quickly thanks to forced air circulation. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration ensures a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the unit size within the series.ControlCOCKPIT SingleDISPLAY and data acquisitionThe UN55 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a high-resolution TFT colour graphics display. The following can be set: temperature in Celsius or Fahrenheit, the position of the exhaust air damper, the programme duration, as well as the time zone and summer/winter time; the parameter for the recirculation fan speed is omitted due to the design. A digital countdown timer with target time can be set from 1 minute to 99 days; the SetpointWAIT function only starts the process time once the setpoint temperature has actually been reached. The data logger can be read out and managed via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity and dimensions of the Memmert universal oven UN55The interior measures 400 x 400 x 330 mm, whilst the external dimensions are 585 x 784 x 514 mm, meaning it has the same footprint as the UN30, but is slightly taller. The scope of delivery includes an electropolished stainless steel grid shelf, and the cabinet can accommodate up to four shelves in total. The maximum load capacity is 80 kg for the entire unit and 20 kg per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UN55 is connected to a 230 V (approx. 2,000 W) or 115 V (approx. 1,700 W) supply, in each case at 50/60 Hz.Selection guide: choosing the right size from the UN seriesThe Memmert universal oven series with natural convection covers a range of internal volumes from 32 to 749 litres. When choosing the right size, the key factors, apart from the internal volume, are the footprint and the number of shelves required; not every larger model takes up more floor space than the next smaller one.ModelInternal volumeUN3032 l, footprint 585 x 434 mm, max. 3 shelvesUN5553 l, footprint 585 x 514 mm, max. 4 shelvesUN7574 l, footprint 585 x 514 mm, max. 6 shelvesUN110108 l, footprint 745 x 584 mm, max. 5 shelvesUN260256 l, footprint 824 x 684 mm, max. 9 shelvesUN450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUN750749 l, footprint 1,224 x 784 mm, max. 14 shelvesThe UN55 is the obvious choice when the UN30 (32 litres) becomes too small for the volume of samples to be processed, but a significantly larger footprint is not yet available. If you need even more shelves whilst maintaining the same footprint, you will find them in the UN75 (74 litres, 6 shelves instead of 4, same footprint, just taller). All seven sizes can be found in our range of climate chambers and incubators.Distinction: UN versus UF, and when to use which displayWithin the Memmert family of heating and drying ovens, the most important purchasing decision is between natural convection (UN series) and forced air circulation (UF series). The UF models feature an electronically controlled air turbine, which actively distributes heat throughout the interior, thereby achieving shorter heating times; however, this only applies from 10 °C above room temperature, rather than from 5 °C as with the UN55. For samples sensitive to dust or air movement, such as loose powders or fibres, natural convection remains the more suitable choice. A direct forced-air equivalent of a similar size is the Memmert universal oven UF55 with 53 litres. Anyone looking for an even more compact natural convection solution will find it in the Memmert universal oven UN30 with 32 litres. All standard models in the UN series, including the UN55, operate with the ControlCOCKPIT SingleDISPLAY; the TwinDISPLAY variant, featuring two displays and additional safety and logging functions, is reserved for Memmert’s ‘plus’ models and is not part of this series.Safety according to DIN 12880In addition to adjustable electronic temperature monitoring, the UN55 features a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature rises to approximately 20 °C above the maximum cabinet temperature. A self-diagnostic system assists with fault-finding, and three freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a minimum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side in relation to the wall or an adjacent unit. The unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 %, non-condensing. Electrically, the UN55 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning agents. As an electrical appliance, the UN55 is subject to the German Electrical and Electronic Equipment Act (ElektroG) at the end of its service life and must not be disposed of with household waste; see Regulatory information below.Typical applicationsWith an internal volume of 53 litres and natural convection, the Memmert universal oven UN55 is suitable for laboratories that require slightly more capacity than a standard benchtop unit but still wish to operate in a vibration-free environment.Drying laboratory glassware and medium-sized sample batchesVibration-free drying of samples and powders that are sensitive to dust or airTempering, ageing and baking of material samples in routine operationsTesting and curing in quality assuranceA second unit alongside a UN30, as the sample volume increasesInvestment rationale: Equipment tailored to the specific purposeThe scope of delivery for the UN55 includes 1 electropolished stainless steel grid shelf; the oven is designed to accommodate up to 4 shelves. Those who regularly run several batches in parallel should order additional grid shelves or perforated trays. A full-view glass door is available as an option for visual inspection without opening the door, which reduces temperature fluctuations inside the chamber, as are interior lighting and an internal power socket for additional measurement equipment. Those wishing to use the data logger on a permanent basis, rather than just with the time-limited trial version, should add an AtmoCONTROL software licence and, if required, a USB-to-Ethernet adapter. For pharmaceutical or standards-based applications, calibration, IQ/OQ/PQ and maintenance services are available, including DAkkS calibration on request.Frequently asked questions before making a purchaseIs natural convection sufficient for uniform drying?For most routine applications, yes. For very densely loaded batches with widely varying sample sizes, a forced-air model such as the UF160 distributes the heat more actively; for dust- or air-sensitive samples, the gentle natural convection of the UN55 is advantageous.How many samples can fit into the UN55 at any one time?One grid shelf is included as standard; up to four shelves, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 80 kg.Can I place the UN55 on the laboratory bench?Yes, with a net weight of around 57 kg and a footprint of 585 x 514 mm, the UN55 is designed for use on a laboratory bench, provided that the bench can safely support the load.What is the accuracy of the temperature control?0.1 °C to 99.9 °C and 0.5 °C from 100 °C onwards, as the UN55, like all models in the UN series, measures using a DIN Class A Pt100 sensor with 4-wire technology.Is a glass door available as an option?A fully transparent glass door is one of the common options for the UN55 and can be selected when placing your order.How does the UN55 differ from the smaller UN30?Both operate using natural convection and feature the same ControlCOCKPIT SingleDISPLAY; the UN55 offers greater capacity, 53 litres instead of 32, and 4 shelves instead of 3, whilst occupying a similar footprint.Is the UN55 suitable for continuous operation overnight?The mechanical temperature limiter, of protection class 1 according to DIN 12880 switches the heater off at an excess temperature of approximately 20 °C and is designed for unattended operation.Technical detailsAdjustable temperature range20 to 300 °CWorking temperature rangeat least 5 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensorPt100, DIN Class A, 4-wire measurementInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mmExternal dimensions of the housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kg230 V connection50/60 Hz, approx. 2,000 W115 V connection50/60 Hz, approx. 1,700 WShelves max.4Shelves included in the scope of delivery1Max. load on the unit80 kgMax. load per shelf20 kgInterior materialsStainless steel, 4-sided all-round heatingHousing materialTextured stainless steel, galvanised sheet steel rear panelControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayTimer1 minute to 99 days, digital countdown clockPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMax. installation altitude2,000 mLabellingCE, EAC, UL marksScope of delivery1x Memmert universal oven UN55Factory calibration certificate (calibration at 160 °C)Fully insulated stainless steel door with a 2-point locking system (compression door lock)1x stainless steel grid shelf, electropolishedRegulatory informationThe Memmert universal oven UN55 is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit.

The Memmert UF55plus universal oven brings the series’ TwinDISPLAY safety features to the smallest forced-air model: 53 litres’ internal volume, a temperature range of 20 to 300 °C, and two redundant Pt100 sensors that monitor each other. If one fails, the second automatically takes over its function. For laboratories that do not want to compromise on process reliability, even with small batches, the UF55plus is therefore the logical alternative to the SingleDISPLAY base model, without taking up any extra floor space.Forced air circulation with redundant temperature measurement in a very compact spaceThe UF55plus’s air turbine, which can be electronically controlled in 10 % increments, actively distributes heat throughout the interior and operates within a temperature range of at least 10 °C above room temperature up to 300 °C. Two DIN Class A Pt100 sensors in a 4-wire configuration monitor each other and ensure a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, even in the event of a sensor failure. Preheated fresh air is introduced via an electronically adjustable exhaust air damper; the exhaust air outlet with throttle valve can also be controlled electronically.ControlCOCKPIT TwinDISPLAY: HeatBALANCE and AutoSAFETYThe UF55plus is controlled via the ControlCOCKPIT TwinDISPLAY, which features two high-resolution TFT colour graphic displays. The HeatBALANCE function allows for fine-tuning of the heat output distribution between the upper and lower heating groups from -50 to +50 %. AutoSAFETY also monitors over- and under-temperature conditions, automatically tracks the setpoint within a freely selectable tolerance range and triggers visual and audible alarms in the event of a deviation; if the setpoint is exceeded, the heating system switches off. Programmes are programmed, managed and transferred via the Ethernet interface or USB port using the AtmoCONTROL software.Capacity and dimensions of the Memmert universal oven UF55plusThe internal dimensions are 400 x 400 x 330 mm; the external dimensions of the housing are 585 x 784 x 514 mm, and the net weight is approximately 57 kg, identical to that of the base model UF55. One electropolished stainless steel grid shelf is included as standard; up to four shelves are possible in total. The maximum total load is 80 kg, with up to 20 kg permitted per shelf. The interior consists of easy-to-clean stainless steel, reinforced by deep-drawn ribbing, with protected, integrated 4-sided all-round heating; the housing is made of textured stainless steel with a fully galvanised sheet steel rear panel. The UF55plus can be connected either to 230 V (approx. 2,000 W) or 115 V (approx. 1,700 W), in both cases at 50/60 Hz.Choosing the right size from the UF rangeThe eight models in the Memmert UF range, which feature forced air circulation, have internal volumes ranging from 53 to 1,060 litres and are each available with TwinDISPLAY. When selecting the right model, the key factors to consider, alongside the volume, are the footprint and the number of shelves required.ModelInternal volumeUF5553 l, footprint 585 x 514 mm, max. 4 shelvesUF7574 l, footprint 585 x 514 mm, max. 6 shelvesUF110108 l, footprint 745 x 584 mm, max. 5 shelvesUF160161 l, footprint 745 x 584 mm, max. 8 shelvesUF260256 l, footprint 824 x 684 mm, max. 9 shelvesUF450449 l, footprint 1,224 x 784 mm, max. 8 shelvesUF750749 l, footprint 1,224 x 784 mm, max. 14 shelvesUF10601,060 l, footprint 1,224 x 1,035 mm, max. 14 shelvesWithin this range, the UF55plus marks the entry-level model featuring the TwinDISPLAY system. If you require more shelves whilst maintaining the same footprint, you will find them in the Memmert universal oven UF75plus (74 litres, 6 shelves instead of 4). You can find all sizes in this range in our range of climate chambers and incubators.Differences between TwinDISPLAY, SingleDISPLAY and natural convectionAnyone who can do without sensor redundancy can save money with the Memmert universal oven UF55 in the basic model with SingleDISPLAY. For samples that are sensitive to dust or air movement and cannot tolerate active air circulation, the Memmert universal oven UN55plus offers the same housing, but with natural convection instead of an air turbine, and still featuring TwinDISPLAY. Anyone needing more capacity whilst maintaining the same footprint will find it in the Memmert universal oven UF75plus.Safety according to DIN 12880, enhanced by AutoSAFETYIn addition to the adjustable electronic temperature monitoring and AutoSAFETY, the UF55plus is fitted with a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature rises to approximately 20 °C above the maximum cabinet temperature. The display also allows you to select either an adjustable temperature monitor (protection class 3.1) or an adjustable temperature limiter (protection class 2). An integrated self-diagnostic system assists with fault-finding, and 3 freely selectable temperature values can be calibrated. The unit bears CE and EAC markings as well as a UL mark.Installation, operation and disposalFor operation, a minimum distance of 15 cm from the wall and a minimum distance of 20 cm from the ceiling must be maintained; a minimum of 5 cm is sufficient on either side in relation to the wall or an adjacent unit. The unit may be installed at altitudes of up to 2,000 m above sea level at an ambient temperature of 5 °C to 40 °C and a relative humidity of no more than 80 %, non-condensing. Electrically, the UF55plus is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned using standard laboratory cleaning agents. As an electrical appliance, the UF55plus is subject to the German Electrical and Electronic Equipment Act (ElektroG) at the end of its service life and must not be disposed of with household waste; see Regulatory information below.Typical applicationsWith an internal volume of 53 litres and redundant sensor technology, the Memmert universal oven UF55plus is suitable for compact laboratory workstations with heightened requirements for process reliability, such as in quality assurance or training laboratories, where several smaller cabinets operate in parallel and unattended.Unattended drying of small batches overnight or at the weekendTempering and baking of material samples, subject to documentation requirementsTesting and curing in quality assurance in the smallest of spacesTime-critical sample preparation requiring high reliabilityAn introduction to TwinDISPLAY equipment for laboratories with limited floor spaceWhen TwinDISPLAY is worthwhileThe scope of delivery for the UF55plus includes 1 electropolished stainless steel grid shelf; the oven is designed to accommodate up to 4 shelves. TwinDISPLAY is particularly worthwhile where processes run unattended overnight and a sensor failure would jeopardise the batch, even if that batch is small. Those who do not require this redundancy can save money by opting for the Memmert universal oven UF55 in its basic model. A fully transparent glass door is available as an option for visual inspection without opening the door, as are interior lighting and an internal power socket. A USB-to-Ethernet adapter and AtmoCONTROL software licences are available for continuous data logging. For pharmaceutical or standards-based applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including DAkkS calibration on request. Those who regularly run additional batches in parallel can use two UF55plus units instead of a larger cabinet, as two small units can be adjusted more flexibly to different set temperatures than a single large cabinet.Frequently asked questions before making a purchaseWhat are the specific benefits of the second Pt100 sensor?If one of the two sensors fails, the second one automatically takes over temperature monitoring, offering an added safety feature compared with the single-sensor system of the basic model, even for small batches.How many samples can fit into the UF55plus at the same time?One grid shelf is included as standard; up to four shelves, each with a maximum load of 20 kg, are possible, giving a total load capacity of up to 80 kg.Is TwinDISPLAY worth it for such a small oven?If work is carried out overnight without supervision or if there is a requirement to keep records, then yes. For simple drying tasks during the day, the Memmert universal oven UF55 basic model is usually sufficient.Can I place the UF55plus on a laboratory bench?Yes, with a net weight of around 57 kg and a footprint of 585 x 514 mm, the UF55plus is designed for use on a laboratory bench, provided that the bench can safely support the load.What is the accuracy of the temperature control?0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of which of the two redundant Pt100 sensors is currently taking the measurement.Is a natural convection version available with TwinDISPLAY?Yes, the Memmert universal oven UN55plus shares the same housing as the UF55plus, but operates without an air turbine.How does the UF55plus differ from the larger UF75plus?Both feature TwinDISPLAY and two redundant Pt100 sensors; the UF75plus offers greater capacity, 74 litres instead of 53, and 6 shelves instead of 4, whilst occupying the same floor space.Technical detailsAdjustable temperature range20 to 300 °CWorking temperature rangeat least 10 °C above room temperature up to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensor2x Pt100, DIN Class A, 4-wire measurement, redundantInternal volume53 lInternal dimensions (W x H x D)400 x 400 x 330 mm (depth minus 39 mm for the fan)External dimensions of the housing (W x H x D)585 x 784 x 514 mmNet weightapprox. 57 kg230 V connection50/60 Hz, approx. 2,000 W115 V connection50/60 Hz, approx. 1,700 WShelves max.4Shelves included in the scope of delivery1Max. load on the unit80 kgMax. load per shelf20 kgInterior materialsStainless steel, 4-sided all-round heatingHousing materialTextured stainless steel, galvanised sheet steel rear panelControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysAdditional functionsHeatBALANCE, AutoSAFETY, visual and audible alarmPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMax. installation altitude2,000 mLabellingCE, EAC, UL marksScope of delivery1x Memmert universal oven UF55plusFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel door with a 2-point locking system (compression door lock)1x stainless steel grid shelf, electropolishedRegulatory informationThe Memmert universal oven UF55plus is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Installation in a wall openingFor fixed installation in a wall opening, Memmert offers a flush-fit unit.

The Memmert UN55plus universal oven handles drying and heating tasks without an air turbine, by natural convection alone, and with 53 litres of interior and up to four shelves it offers more capacity than the smallest model of the series. The setting temperature range extends from +20 to +300 °C, and two DIN class A Pt100 sensors monitor each other in 4-wire measurement and automatically take over the function of the other in the event of a fault.Safety with AutoSAFETY, heating power with HeatBALANCEA mechanical temperature limiter of protection class 1 according to DIN 12880 switches off the heating at around 20 °C above the maximum oven temperature, and an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2 can also be selected. AutoSAFETY automatically follows the setpoint at a freely selectable distance and reports deviations visually and audibly. The HeatBALANCE function additionally allows the heating power distribution between the upper and lower heating group to be adjusted from -50 to +50 %, and a self-diagnosis system helps with fault finding.Interior, load and connectionThe interior measures 400 x 400 x 330 mm and is deep-drawn ribbed with protected, integrated 4-sided all-round heating, and the external dimensions are 585 x 784 x 514 mm plus 56 mm for the door handle. One stainless steel grid shelf is part of the standard equipment, up to four shelves are possible, and a total load of 80 kg is permitted with a maximum of 20 kg per shelf. The UN55plus is connected with 230 V at approx. 2,000 W, and 115 V at approx. 1,700 W is available as a factory option at no extra charge, in each case 50/60 Hz.Control via the ControlCOCKPITThe oven is controlled via the ControlCOCKPIT with two TFT colour graphic displays (TwinDISPLAY), and the setting accuracy is 0.1 °C up to a setpoint temperature of 99.9 °C and 0.5 °C from 100 °C. The SetpointWAIT function starts the process time only after the setpoint temperature has been reached, and a digital countdown timer covers target times from 1 minute to 99 days. Programming and management are done via the Ethernet interface or USB port with the AtmoCONTROL software, and the programme sequence is retained in the event of a power failure.Guide to choosing the right sizeAnyone who can manage with less weight and wants to save floor space will find the more compact alternative in the UN30plus with 32 litres.
