Memmert levelling base frame B29753, height 500 mm, for size 450

The Memmert UN450plus universal oven stands on castors that can be moved and locked, and with 449 litres of interior it offers the second-largest volume of the UN-plus series. Up to eight shelves can be loaded at the same time, and it is connected with 400 V and 3 x 230 V at approx. 5,800 W. The net weight is around 161 kg.Floor-standing unit with a large interiorThe unit measures 1,040 x 720 x 600 mm internally and 1,224 x 1,247 x 784 mm externally plus 56 mm for the door handle. The stainless steel doors are fully insulated and have 2-point locking with a compression door lock. Two stainless steel grid shelves are part of the standard equipment, and up to 300 kg total load is permitted with a maximum of 30 kg per shelf.Sensors and controlTwo 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. On the ControlCOCKPIT with two TFT colour graphic displays, the setting accuracy is 0.1 °C up to 99.9 °C setpoint temperature and 0.5 °C above that. Three freely selectable temperature values can be calibrated, and programmes are created and managed via Ethernet or USB with AtmoCONTROL.Temperature protection for large batchesA mechanical temperature limiter of protection class 1 according to DIN 12880 switches off the heating approx. 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 additionally be selected on the display. AutoSAFETY follows the setpoint at a freely selectable distance and triggers a visual and audible alarm when the temperature exceeds or falls below it. HeatBALANCE shifts the heating power distribution between the upper and lower heating group by -50 to +50 %, and a self-diagnosis system supports fault finding.Guide to choosing the right sizeIf a single-phase connection and a smaller volume are sufficient, the UN260plus with 256 litres and 230 V technology is the more compact alternative without the need for a three-phase supply. For even larger quantities, the UN750plus with 749 litres and up to 14 shelves is available, see the size table below.Typical applicationsThe UN450plus is suitable for drying, heating, tempering, ageing, baking, testing and curing in research, science, industry and quality assurance.Drying and heating larger quantities of material with up to eight shelvesAgeing and testing in industry and researchBaking and curing as part of quality assuranceTechnical detailsSetting temperature range+20 to +300 °CWorking temperature rangemin. 5 °C above room temperature 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 volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,247 x 784 mm (plus 56 mm door handle)Net weightapprox. 161 kgConnection400 V and 3 x 230 V without neutral conductor, 50/60 Hz, approx. 5,800 WShelves max.8Shelves included in scope of delivery2Max. load of unit300 kgMax. load per shelf30 kgInstallation of housingmobile and lockable, on castorsInteriordeep-drawn ribbed, 4-sided all-round heatingControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displayAdditional functionsHeatBALANCE, AutoSAFETY, visual and audible alarmPermissible ambient temperature+5 °C to +40 °CPermissible humiditymax. 80 % rel., non-condensingMax. installation altitude2,000 mMarkingsCE, VDE GS, UL, EACOther sizes in the seriesWith natural convection, the UN-plus series covers eight sizes from 32 to 749 litres, listed here in ascending order of internal volume:ModelInternal volumeSetting temperatureDisplayUN30plus32 l+20 to +300 °CTwinDISPLAYUN55plus53 l+20 to +300 °CTwinDISPLAYUN75plus74 l+20 to +300 °CTwinDISPLAYUN110plus108 l+20 to +300 °CTwinDISPLAYUN160plus161 l+20 to +300 °CTwinDISPLAYUN260plus256 l+20 to +300 °CTwinDISPLAYUN450plus (this page)449 l+20 to +300 °CTwinDISPLAYUN750plus749 l+20 to +300 °CTwinDISPLAYWith SingleDISPLAY, the same volume is available in the UN series: UN450.Scope of delivery1x Memmert universal oven UN450plusFactory calibration certificate (calibration at +160 °C)Fully insulated stainless steel doors with 2-point locking (compression door lock)2x stainless steel grid shelves, electropolishedRegulatory informationThe device is an electrical device within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The Memmert UF450plus universal oven combines the series’ medium-sized 449-litre capacity with the TwinDISPLAY safety features: two redundant Pt100 sensors, HeatBALANCE and AutoSAFETY ensure process reliability even during long, unattended runs. The temperature range extends from 20 to 300 °C, whilst the electronically controlled air turbine actively distributes the heat throughout the interior. Fitted with castors that can be locked in place, the cabinet, which weighs around 161 kg, can be moved despite its size. The UF450plus also serves as the technical basis for the medical version, the UF450mplus, which is designed for a different purpose.Forced air circulation with redundant temperature measurementThe UF450plus’s air turbine, which is electronically controllable in 10 % increments, actively distributes the heat throughout the interior and achieves an operating temperature range from 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; if one fails, the second automatically takes over its function. The setting accuracy is 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards. 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 UF450plus 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 %, for example to compensate for temperature differences caused by unevenly distributed loads. 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. Programmes are programmed, managed and transferred via an Ethernet interface or USB port using the AtmoCONTROL software. A programmable door lock and a door-open detection feature can be added as optional extras.Capacity and connections of the Memmert UF450plus universal ovenThe interior measures 1,040 x 720 x 600 mm and accommodates 2 electropolished stainless steel grid shelves as standard; up to 8 shelves are possible in total. The permissible total load is up to 300 kg, with a maximum of 30 kg per shelf. The external dimensions of the cabinet are 1,224 x 1,247 x 784 mm, and the net weight is approximately 161 kg. 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 UF450plus is connected to a 400 V three-phase supply and 3 x 230 V without a neutral conductor at 50/60 Hz, with a power consumption of around 5,800 W.Choosing the right size from the UF rangeEight sizes ranging from 53 to 1,060 litres internal volume make up the Memmert UF range with forced air circulation, each also available with TwinDISPLAY. When selecting the appropriate size, the key factors, 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 shelvesThe UF450plus sits between the Memmert UF260plus universal oven (256 litres) and the very large models starting at 749 litres. If you require even more capacity, you will find it in the Memmert UF750plus universal oven. You can find all sizes in this range in our Climate Chambers & Incubators range.Differences from SingleDISPLAY, natural convection and the medical versionThose who can do without sensor redundancy can save money with the Memmert UF450 universal oven in the basic model with SingleDISPLAY. For samples sensitive to dust or air movement, the Memmert UN450plus universal oven offers the same housing with natural convection instead of an air turbine, whilst retaining the TwinDISPLAY. A third variant is the Memmert UF450mplus universal oven, which is largely identical in design but is classified as a Class I medical device intended for heating and maintaining the temperature of fango, silicate and APS packs in physiotherapy, rather than for laboratory drying and tempering processes. Anyone looking for a laboratory or industrial unit should opt for the UF450plus described here, rather than the mplus model.Safety according to DIN 12880, enhanced by AutoSAFETYIn addition to the adjustable electronic temperature monitoring and AutoSAFETY, the UF450plus features a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. The display also allows you to select either an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of 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 clearance of 15 cm from the wall and a minimum clearance of 20 cm from the ceiling must be maintained; a minimum clearance of 5 cm is sufficient on the sides from the wall or an adjacent unit. Installation is permitted 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 cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. Thanks to its castors, the UF450plus can still be moved within these specifications even after installation. As an electrical appliance, at the end of its service life it is subject to the Electrical and Electronic Equipment Act and must not be disposed of with household waste; see Regulatory information below.Typical applicationsWith an internal volume of 449 litres and redundant sensor technology, the Memmert UF450plus universal oven is suitable for medium to large batches with increased requirements for process reliability.Unattended drying and tempering overnight or at weekendsMaterial testing in industrial manufacturing where documentation is requiredCuring and testing in quality assurance with medium to high sample volumesHeat treatment processes in science and research with long process timesAn intermediate size for laboratories that require more capacity than the UF260plus can provideWhen TwinDISPLAY is worthwhileThe scope of delivery for the UF450plus includes 2 electropolished stainless steel grid shelves; the cabinet is designed to accommodate up to 8 shelves. TwinDISPLAY is particularly worthwhile where processes run unattended overnight or at weekends and where a sensor failure would otherwise jeopardise the entire batch. Those who do not require this redundancy can save money by opting for the Memmert UF450 universal oven in its basic model. A fully transparent glass door is available as an option for visual inspection without opening the door, as is a programmable door lock with door-open detection and a potential-free alarm contact for connection to a building management system. For pharmaceutical or standard-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including those accredited by DAkkS.Frequently asked questions before purchaseWhat are the specific benefits of the second Pt100 sensor?The two sensors monitor each other; if one sensor fails, the process continues uninterrupted using the second one.How many shelves fit into the UF450plus?Two grid shelves are included as standard; up to 8 shelves, each with a maximum load of 30 kg, are possible, with a total load capacity of up to 300 kg.Is the UF450plus the same unit as the medical UF450mplus?Technically, they are largely identical in construction, but the Memmert UF450mplus universal oven is a Class I medical device for physiotherapy, whereas the UF450plus is intended for laboratory and industrial applications.Is TwinDISPLAY worth it for routine operation?For simple drying tasks during the day, SingleDISPLAY is usually sufficient. For unattended overnight runs, the UF450plus is the safer choice compared to the Memmert UF450 universal oven.What power supply is required?400 V three-phase current with 3 x 230 V without a neutral conductor at 50/60 Hz and a power consumption of approximately 5,800 W.Is a natural convection version with TwinDISPLAY available?Yes, the Memmert UN450plus universal oven shares the same housing as the UF450plus, but operates without an air turbine.Is the UF450plus mobile?Yes, it is mobile and lockable on castors and can be repositioned within the permitted installation conditions despite its net weight of around 161 kg.Technical detailsAdjustable temperature range20 to 300 °COperating 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 volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mm (depth minus 39 mm for the fan)External dimensions of housing (W x H x D)1,224 x 1,247 x 784 mmNet weightapprox. 161 kgConnection400 V and 3 x 230 V, 50/60 Hz, approx. 5,800 WMaximum number of shelves8Shelves included in scope of delivery2Max. load on unit300 kgMax. load per shelf30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysAdditional functionsHeatBALANCE, AutoSAFETY, visual and audible alarmInstallationMobile and lockable on castorsPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80 % relative, non-condensingMaximum installation height2,000 mMarkingsCE, EAC, UL marksScope of delivery1x Memmert UF450plus universal ovenFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door lock)2x stainless steel grid shelf, electropolishedRegulatory informationThe Memmert UF450plus universal oven is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Individual requirements and procurement serviceOptions available for the UF450plus include fully transparent glass doors, interior lighting and a power socket, a gas-tight interior, a potential-free alarm contact, MobileALERT remote monitoring, and a USB user ID stick for TwinDISPLAY user rights.

Through our procurement service, we are happy to assist you with procurement and configuration.

With an internal volume of 449 litres, the Memmert UF450 universal oven is the large floor-standing model of the UF range and is designed for batches that no longer fit into smaller ovens. Like the more compact Memmert UF160 universal oven, it features an air turbine with electronic control in 10 % increments for forced air circulation and covers a temperature range from 20 to 300 °C. Fitted with castors that can be moved and locked in place, the cabinet, which weighs around 161 kg, can be moved around the laboratory or production hall despite its size, without having to be lifted each time.Forced air circulation on a large scale: even heat distribution even when the interior is fullWith an internal volume of 449 litres and up to 8 shelves, the active air circulation is particularly noticeable: without an air turbine, the heat would be distributed much more unevenly within such a large interior and would rise more slowly. The UF450’s electronically controlled air turbine ensures that the working temperature range, which, as with all UF models, is at least 10 °C above room temperature up to 300 °C, is reliably achieved even with large, densely packed batches. A DIN Class A Pt100 temperature sensor with 4-wire measurement provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, regardless of the size of the unit.ControlCOCKPIT SingleDISPLAY and three-phase power supply for industrial useThe UF450 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphics display, which can be used to set the temperature, forced air circulation motor speed, exhaust air damper position, programme duration and time zone. A digital countdown timer ranging from 1 minute to 99 days and the SetpointWait function, which only starts the process time once the setpoint temperature has been reached, ensure reproducible processes even during long, unattended runs. As an oven of this size requires correspondingly higher heating power, the UF450 is powered by 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz and with a power consumption of approximately 5,800 W, rather than the single-phase connection used by the smaller models. The data logger can be read via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity of the Memmert UF450 universal oven for large batchesThe interior measures 1,040 x 720 x 600 mm; the external dimensions of the cabinet are 1,224 x 1,247 x 784 mm. There is space for up to 8 shelves, and 2 electropolished stainless steel grid shelves are included in the scope of delivery. The UF450 can be loaded with up to 300 kg in total; each shelf can hold up to 30 kg, which is significantly more than the UF160 and considerably more than the compact UN30. 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 fully insulated stainless steel doors are secured by a two-point locking mechanism with a compression door lock.Selection guide: choosing the right size from the UF rangeThe Memmert UF range comprises eight models with internal volumes ranging from 53 to 1,060 litres, all featuring forced air circulation and available with TwinDISPLAY. When selecting the right size, the key factors to consider, alongside the internal 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 shelvesThe UF450 sits between the more compact Memmert UF260 universal oven (256 litres) and the very large models, starting at 749 litres. Anyone who needs even more space will find it in the Memmert UF750 universal oven, also available on castors. You can find all sizes in this range in our Range of climate chambers & Incubators.Distinction: TwinDISPLAY and the natural convection variantWithin the UF450 series, the most important decision is whether to choose SingleDISPLAY or TwinDISPLAY. The UF450 described here operates with a single Pt100 sensor and one display; for unattended processes with higher safety requirements, the identically constructed Memmert UF450plus universal oven offers two redundant Pt100 sensors, the HeatBALANCE function for fine-tuning the distribution of heating power, and the additional AutoSAFETY monitoring, each with two TFT displays instead of one. For those who can do without active air circulation entirely, for example, because dust-sensitive samples are laid out in the open, the Memmert UN450 universal oven is the counterpart, featuring natural convection instead of an air turbine, whilst retaining the same internal volume of 449 litres.Safety according to DIN 12880 for long, unattended processesProcess reliability is crucial, particularly for large-volume batches that often run overnight or for several days. The UF450 features adjustable electronic temperature monitoring plus a mechanical temperature limiter of 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.Use, installation and disposalDespite its size, the same spacing requirements apply to the Memmert UF450 universal oven as to the smaller models: a minimum clearance of 15 cm from the wall, a minimum clearance of 20 cm from the ceiling and a minimum clearance of 5 cm to the side from a wall or adjacent unit, even though the cabinet can be easily manoeuvred into the correct position thanks to its castors. It may be installed at altitudes of up to 2,000 m above sea level at ambient temperatures of 5 °C to 40 °C and a maximum relative humidity of 80 %, non-condensing. Electrically, the UF450 is designed for overvoltage category II and pollution degree 2; despite the castors, it must only be transported in an upright position. The interior, made of easy-to-clean stainless steel, can be cleaned with standard laboratory cleaning agents, even with frequent batch changes. As an electrical appliance, the UF450 is subject to the Electrical and Electronic Equipment Act 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 449 litres, up to 8 shelves and a load capacity of up to 300 kg, the Memmert UF450 universal oven is designed for applications with higher throughput.Large-volume drying and heat treatment batches in industry and researchRoutine tempering, ageing and baking of material samplesMaterial testing and quality assurance with high sample throughputCuring processes in which several shelves are loaded simultaneouslyMobile use at different locations thanks to a wheeled baseInvestment rationale: when TwinDISPLAY is worthwhileThe scope of delivery for the UF450 includes 2 electropolished stainless steel grid shelves; the cabinet is designed to accommodate up to 8 shelves. TwinDISPLAY is particularly worthwhile where processes run unattended overnight or at weekends and where a sensor failure would otherwise jeopardise the entire, often large-volume batch: in such cases, the Memmert UF450plus universal oven is the safer choice. For daytime operation under supervision, the SingleDISPLAY model described here is sufficient. For visual inspection without opening the door, a full-view glass door up to 300 °C is available as an option, as is a lockable door with a security lock and interior lighting. For process monitoring, a 4-20 mA current interface, fan speed monitoring and door-open detection are also available. For pharmaceutical or standard-compliant applications, we arrange calibration, IQ/OQ/PQ services according to DIN 12880 and maintenance contracts.Frequently asked questions before making a purchaseHow many samples can the UF450 hold at one time?Two grid shelves are included as standard; up to 8 shelves are possible, each with a maximum load of 30 kg, for a total load capacity of up to 300 kg.Can the cabinet be moved around in the laboratory?Yes, the UF450 is fitted with castors that allow it to be moved and locked in place, and can be repositioned within the permitted installation conditions despite its net weight of around 161 kg.What type of power connection is required?The UF450 requires 400 V three-phase current at 3 x 230 V without a neutral conductor at 50/60 Hz and has a power consumption of around 5,800 W; a single-phase 230 V connection is not sufficient for a unit of this size.How does the UF450 differ from the UF450plus?Both share the same housing and air turbine; the UF450plus also features two redundant Pt100 sensors, TwinDISPLAY, HeatBALANCE and AutoSAFETY for greater process reliability during unattended operation.Is a natural convection model available in this size?Yes, the Memmert UN450 universal oven offers the same internal volume of 449 litres, but operates without an air turbine and is suitable for samples that are sensitive to dust or air movement.What is the accuracy of the temperature control?0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, measured using a DIN Class A Pt100 sensor with a 4-wire connection.Is the UF450 suitable for continuous overnight operation?The mechanical temperature limiter, of protection class 1 according to DIN 12880, switches the heater off when the temperature exceeds approximately 20 °C and is designed for unattended operation.How do I clean the interior between two batches?The interior is made of easy-to-clean stainless steel and can be cleaned using standard laboratory cleaning products without exposing the 4-sided all-round heating system.Technical detailsSetting 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 volume449 lInternal dimensions (W x H x D)1,040 × 720 × 600 mm (depth minus 39 mm for the fan)External dimensions of the housing (W x H x D)1,224 × 1,247 × 784 mmNet weightapprox. 161 kgConnection400 V and 3 x 230 V without neutral conductor, 50/60 Hz, approx. 5,800 WMaximum number of shelves8Shelves included in the scope of delivery2Max. load on the unit300 kgMaximum load per shelf30 kgInterior materialsStainless steel, 4-sided all-round heatingHousing materialTextured stainless steel, galvanised sheet steel rear panelControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphics displayInstallationmovable and lockable on castorsTimer1 minute to 99 days, digital countdown clockPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % relative humidity, non-condensingMaximum installation height2,000 mMarkingsCE, EAC, UL test markScope of delivery1x Memmert UF450 universal ovenFactory calibration certificate (calibration at 160 °C)Fully insulated stainless steel doors with a 2-point locking system (compression door lock)2x stainless steel grid shelves, electropolishedRegulatory informationThe Memmert UF450 universal oven is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Individual requirements and procurement serviceThe UF450 is available with, amongst other features, full-view glass doors up to 300 °C, a lockable door with a security lock, interior lighting, reinforced grid shelves and perforated sheets up to 60 kg, as well as a gas-tight version with various pipe feed-throughs.

Through our procurement service, we are happy to assist you with procurement and configuration.

The Memmert UN450 universal oven offers an internal volume of 449 litres within a comparatively modest overall height of 1,247 mm, meaning it fits even under lower ceilings where a taller model would not. Like all natural convection models in the series, it operates without a fan in the temperature range from 20 to 300 °C and is powered by three-phase current due to the heating power required. For industrial and research facilities wishing to heat-treat large batches without vibration, without needing a particularly tall unit, the UN450 is the suitable solution.Natural convection with a large internal volumeEven with an internal volume of 449 litres, the Memmert UN450 universal oven does not require an air turbine or a forced air circulation motor. Heat rises purely by convection, without a fan stirring up dust or light sample particles within the large interior. The working temperature range extends from at least 5 °C above room temperature up to 300 °C. Natural convection remains in high demand even in this size category, particularly for industrial material samples that must not be affected by air movement. A Pt100 temperature sensor of DIN Class A in a 4-wire configuration provides a setting accuracy of 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards.ControlCOCKPIT SingleDISPLAY and three-phase connectionThe UN450 is controlled via the ControlCOCKPIT SingleDISPLAY, an adaptive, multifunctional digital PID microprocessor controller with a TFT colour graphic display, which can be used to set the temperature, exhaust air damper position, programme duration and time zone. A digital countdown timer ranging from 1 minute to 99 days and the SetpointWAIT function, which only starts the process time once the setpoint temperature has been reached, ensure reproducible processes, even during long, unattended runs. As a chamber of this size requires correspondingly higher heating capacity, the UN450 is powered by 400 V three-phase current and 3 x 230 V without a neutral conductor at 50/60 Hz and with a power consumption of approximately 5,800 W, rather than the single-phase connection used by the smaller models. The data logger can be read via the Ethernet interface; a time-limited trial version of the AtmoCONTROL software is available for download.Capacity of the Memmert UN450 universal ovenThe internal dimensions are 1,040 x 720 x 600 mm; the external dimensions of the cabinet are 1,224 x 1,247 x 784 mm. There is space for up to 8 shelves; 2 electropolished stainless steel grid shelves are included in the scope of delivery. The UN450 can be loaded with a total of up to 300 kg; each shelf can hold up to 30 kg, which is more than the smaller UN models, which allow 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 fully insulated stainless steel doors are secured by a 2-point locking mechanism with a compression door lock.Same footprint, different heightsWithin the Memmert UN series with natural convection, the internal volume ranges from 32 to 749 litres. The UN450 and UN750 share the same floor space and differ only in their overall height, which is an important selection criterion where room heights are low.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 shelvesIf you require the maximum capacity within this footprint and have a room height of more than 1.72 m, choose the Memmert UN750 universal oven with 749 litres and 14 shelves. If a smaller volume with a smaller footprint is sufficient, the Memmert UN260 universal oven with 256 litres is the suitable alternative. The full range of climate chambers and incubators can be found under Climate Chambers & Incubators.Difference between natural convection and forced air circulation, UN450 and UF450In addition to the UN450 with natural convection, there is also the Memmert UF450 universal oven, the structurally identical large forced air circulation version with an electronically controllable air turbine. The UF450 actively distributes heat throughout the interior and reaches its working temperature range from as low as 10 °C above room temperature, which ensures shorter heating times for densely packed batches of varying sizes. The UN450 deliberately avoids this and instead starts operating from just 5 °C above room temperature, with no air movement inside the chamber; this is suitable for large quantities of material samples that are sensitive to dust or vibration. Both models share the same interior, housing and ControlCOCKPIT SingleDISPLAY, but differ in their ventilation principle and working temperature range.Safety according to DIN 12880 for long, unattended processesProcess safety is crucial, particularly for large-volume batches that often run overnight or for several days. The UN450 features adjustable electronic temperature monitoring plus a mechanical temperature limiter of 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 3 freely selectable temperature values can be calibrated. CE and EAC markings, as well as a UL test mark, are provided.Installation, operation and disposalThe same spacing requirements apply to the operation of the UN450 as for the smaller models: a minimum of 15 cm from the wall, a minimum of 20 cm from the ceiling and a minimum of 5 cm to the side, either from a wall or an adjacent unit. Given a net weight of around 161 kg and the three-phase power connection, the installation site should be fitted with a suitable heavy-current power connection prior to delivery. The unit may be installed at altitudes of up to 2,000 m above sea level, at ambient temperatures of 5 °C to 40 °C and with a maximum relative humidity of 80 %, non-condensing. Electrically, the UN450 is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. As an electrical appliance, the UN450 is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste.Typical applicationsWith an internal volume of 449 litres, up to 8 shelves and a load capacity of up to 300 kg, the Memmert UN450 universal oven is designed for high-throughput applications where headroom at the installation site is also limited.Large-volume drying and heat treatment batches in industry and researchRoutine tempering, ageing and baking of material samplesMaterial testing and quality assurance with high sample throughputVibration-free heat treatment of dust-sensitive materials on a large scaleInstallation sites with limited headroom where a UN750 will not fitShelves, access control and process monitoringThe UN450 is supplied with 2 electropolished stainless steel grid shelves as standard; the cabinet is designed to accommodate up to 8 shelves, each with a maximum load of 30 kg. Options for process monitoring include a 4–20 mA current interface, fan speed monitoring, an additional Pt100 sensor and SMS alerts; for controlled access, there is a lockable door with a security lock. Those requiring a gas-tight version with various pipe penetrations can also have this configured. In addition, we arrange base frames with levelling, as well as calibration, IQ/OQ/PQ services according to DIN 12880 and maintenance contracts, including DAkkS calibration on request.Frequently asked questions before purchaseWhy does the UN450 require three-phase power?A cabinet of this size requires significantly more heating power (around 5,800 W) than the smaller UN models; therefore, the UN450 is operated with 400 V three-phase power and 3 x 230 V without a neutral conductor, rather than a single-phase connection.How does the UN450 differ from the UF450?Both share the same interior, housing and control system; however, the UF450 also features an electronically controllable air turbine for active air circulation and starts its working temperature range at 10 °C rather than 5 °C above room temperature.How tall is the UN450 and will it fit under a standard ceiling?The external dimensions are 1,224 x 1,247 x 784 mm; with a height of 1,247 mm, the UN450 also fits into rooms where the taller UN750, at 1,720 mm, would no longer fit.What is the maximum load per shelf?Up to 30 kg per shelf, with a total load of up to 300 kg for the entire unit when fitted with a maximum of 8 shelves.What is the accuracy of the temperature control?Despite the three-phase power supply, the same accuracy applies across the range as for the smaller models: 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C, measured using a DIN Class A Pt100 sensor with 4-wire technology.Is the UN450 suitable for long, unattended processes?The mechanical temperature limiter, of protection class 1 according to DIN 12880, switches off the heating element in the event of an overtemperature of approximately 20 °C. Information on long processes is available on request.Technical detailsSetting 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 volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,247 x 784 mmNet weightapprox. 161 kgConnection400 V and 3 x 230 V without neutral conductor, 50/60 Hz, approx. 5,800 WMaximum number of shelves8Shelves included in the scope of delivery2Max. load capacity300 kgMax. load per shelf30 kgInterior materialStainless steel, 4-sided all-round heatingCasing materialTextured stainless steel, galvanised sheet steel rear panelControl systemControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayTimer1 minute to 99 days, digital countdown timerPermissible ambient temperature5 °C to 40 °CPermissible relative humiditymax. 80 % rel., non-condensingMaximum installation height2,000 mMarkingsCE, EAC, UL test markScope of delivery1x Memmert UN450 universal ovenFactory calibration certificate (calibrated at 160 °C)Fully insulated stainless steel doors with 2-point locking (compression door lock)2x stainless steel grid shelves, electropolishedRegulatory informationThe Memmert UN450 universal oven is registered with the Stiftung Elektro-Altgeräte Register (Stiftung EAR) under WEEE registration number DE 66812464.Individual requirements & procurement serviceOptions available for the UN450 include a lockable door with a security lock, a gas-tight version with various pipe feed-throughs, and reinforced grid shelves and perforated sheets.

The IN450plus has a capacity of 449 litres and is mounted on castors that can be locked in place; it has external dimensions of 1,224 x 1,247 x 784 mm and a net weight of around 161 kilograms. It can accommodate a maximum of eight shelves, one fewer than the smaller IN260plus, which has nine shelves. Temperature control is managed via a ControlCOCKPIT TwinDISPLAY with two Pt100 sensors, operating within a range of +20 to +80 °C.Mobile housing with HeatBALANCEAn electronically adjustable exhaust air damper mixes in preheated fresh air, whilst the exhaust air outlet with throttle valve is electronically controllable. The interior features deep-drawn ribbing with 4-sided all-round heating, whilst the cabinet has a fully galvanised sheet steel rear panel. Those requiring forced air circulation rather than natural convection will find the same size model in the IF-plus series.Two displays, two sensorsTwo DIN Class A Pt100 sensors in a 4-wire configuration take over each other’s function in the event of a fault and supply data to the ControlCOCKPIT TwinDISPLAY, which features two TFT colour graphic displays. The HeatBALANCE function distributes the heating power between the upper and lower heating groups within a range of -50 to +50 %. Ethernet and USB connections are available for programming using the AtmoCONTROL software.Safety levels and sterilisation programmeThe permanently installed sterilisation programme sterilises the interior in 4 hours at 160 °C; the load is excluded from this process. In addition to the mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off at approximately 20 °C above the maximum cabinet temperature, an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2 can be selected via the display. AutoSAFETY triggers a visual and audible alarm in the event of a deviation from the setpoint; the unit must only be transported in an upright position.Selection guide for the correct sizeIf the 256-litre IN260plus proves too small, the mobile IN450plus, with a capacity of 449 litres and castors, offers more volume, with eight shelves instead of nine. For even larger batches, the table below lists the IN750plus, which has a capacity of 749 litres and 14 shelves.Typical applicationsWith a capacity of 449 litres, the mobile IN450plus incubates and temperature-controls larger batches between +20 and +80 °C, including in research applications.Incubating and temperature-controlling large-volume sample quantities across eight shelvesSterilising the interior using the permanently installed programmeUse in researchTechnical detailsSetting temperature range+20 to +80 °CWorking 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 volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mmExternal dimensions of housing (W x H x D)1,224 x 1,247 x 784 mm (depth plus 56 mm for door handle)Net weightapprox. 161 kgConnected load 230 V50/60 Hz, approx. 1,800 WConnected load 115 V50/60 Hz, approx. 1,500 WMaximum number of shelves8Shelves included in scope of delivery2InteriorEasy to clean, reinforced with deep-drawn ribbing, with protected, integrated 4-sided all-round heatingInstallationCan be moved and locked in place, on castorsControlControlCOCKPIT TwinDISPLAY, PID microprocessor controller, 2x TFT colour graphic displaysPermissible ambient temperature+5 °C to +40 °CPermissible relative humiditymax. 80 % non-condensingMaximum installation altitudemax. 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 °CTwinDISPLAYIN55plus53 l+20 to +80 °CTwinDISPLAYIN75plus74 l+20 to +80 °CTwinDISPLAYIN110plus108 l+20 to +80 °CTwinDISPLAYIN160plus161 l+20 to +80 °CTwinDISPLAYIN260plus256 l+20 to +80 °CTwinDISPLAYIN450plus (this page)449 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: IN450.Scope of delivery1x Memmert IN450plus incubatorFactory calibration certificate (calibrated at +37 °C)Fully insulated stainless steel door with 2-point locking (compression door lock)Inner glass door2x stainless steel grid shelf, electropolishedRegulatory informationThis appliance is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

Up to 8 shelves can be loaded at the same time, making the unit suitable for facilities with a high, continuous demand for pre-warmed textiles, without the need for constant replenishment during operation. Generous internal dimensions for high throughput With internal dimensions of 1,040 × 720 × 600 mm, the IF450bw accommodates up to 8 shelves with a maximum total load of 300 kg; each shelf can hold up to 30 kg. Two stainless steel grid shelves are included as standard. An integrated 4-sided all-round heating system, combined with an electronically controlled, low-noise air circulation system set to a fixed 100 %, ensures even temperature distribution throughout the entire interior. With external dimensions of 1,224 × 1,247 × 784 mm (plus 56 mm for the door handle) and a net weight of around 161 kg, the unit is clearly designed as a stationary unit for continuous operation. Precise control, documented calibration An adaptive, multifunctional PID microprocessor controller with a TFT colour graphic display (SingleDISPLAY) controls the unit, whilst a DIN Class A Pt100 sensor with 4-wire measurement ensures a setting accuracy of 0.1 °C. The working range extends from at least 10 °C above room temperature up to +80 °C. A factory calibration certificate at +37 °C is included as standard; the unit is manufactured in the Federal Republic of Germany. This allows the measurement accuracy to be verified ex works, without the need to commission a separate calibration before first use. Safety and self-diagnosis The IF450bw monitors the temperature electronically and additionally via a mechanical temperature limiter. An integrated self-diagnostic system detects faults at an early stage and reports them immediately on the display, so that maintenance requirements can be identified in good time before ongoing operations are noticeably affected. Safety as a medical device The IF450bw is classified as a Class I medical device and has accordingly been tested to VDE, GS, CE and UL. For organisations that prioritise tested, documented equipment safety, the Class I classification is an additional mark of quality. The right size for every requirement The IF450bw is positioned within Memmert’s IF-bw blanket warmer range between the mid-range model IF260bw (256 litres) and the largest model IF750bw (749 litres). All models share the same SingleDISPLAY control technology and operating logic, meaning that a facility with growing requirements can switch to a larger size within the range without any major changes. Operation at 230 V or 115 V With a connected load of around 1,800 W at 230 V or around 1,500 W at 115 V, the IF450bw can be operated depending on the power supply available at the site of use. The electronic control system automatically adjusts the heating output to maintain the setpoint precisely, regardless of the selected mains voltage, even when fully loaded with up to 300 kg of textiles. Ready for dispatch For transport, the IF450bw is designed with packaging dimensions of 1,330 × 1,440 × 1,050 mm; the gross weight, including the carton, is approximately 227 kg. These specifications help in the early planning stages for delivery and installation, for example when door widths, access routes or lift capacities at the destination need to be taken into account in advance. Typical applications With an internal capacity of 449 litres and up to 8 shelves, the IF450bw is suitable for facilities with a high throughput of textiles requiring heating: Simultaneous heating of large quantities of non-sterile towels and blankets across up to 8 shelvesContinuous supply of pre-heated textiles in facilities with high throughputUniform temperature control throughout the entire interior thanks to 4-sided all-round heatingDocumented initial calibration via the supplied factory calibration certificate at +37 °CSuccessor model for facilities that have outgrown the IF260bw, offering significantly higher load capacity per shelfCentral textile heating station for multiple treatment or application rooms simultaneously Technical details Internal volume449 litres Internal dimensions (W×H×D)1,040 × 720 × 600 mm (depth minus 39 mm for the fan) External dimensions (W×H×D)1,224 × 1,247 × 784 mm (+56 mm door handle) Setting temperature range+20 to +80 °C Working temperature rangeat least 10 °C above room temperature up to +80 °C Setting accuracy0.1 °C Sensors1× Pt100 DIN Class A, 4-wire measurement Heating principle4-sided all-round heating, integrated VentilationElectronically controlled, low-noise, 100 % ControlSingleDISPLAY, PID microprocessor controller, TFT colour graphic display SafetyElectronic monitoring, mechanical temperature limiter, self-diagnostic system Shelves2× stainless steel grid shelves, up to 8 shelves, max. 300 kg total / 30 kg per shelf Voltage/Power230 V approx. 1,800 W / 115 V approx. 1,500 W Packaging dimensions1,330 × 1,440 × 1,050 mm Country of originFederal Republic of Germany Net weight/Gross weightapprox. 161 kg / approx. 227 kg (including carton) Scope of delivery 1× Memmert IF450bw blanket warmer (basic unit) 2× stainless steel grid shelves 1× factory calibration certificate (calibrated at +37 °C) Regulatory information The IF450bw is classified as a Class I medical device and has been tested to VDE, GS, CE and UL.

The Memmert universal oven UF450m is the first mobile model of the UF-m series: 449 litres of internal volume on castors, lockable at the desired location. The interior measures 1,040 x 720 x 600 mm and holds up to 8 shelves with up to 30 kg each, up to 300 kg in total. The UF450m is also a Class I medical device under Regulation (EU) 2017/745, intended for heating and keeping warm fango, silicate and APS packs, controlled via the ControlCOCKPIT SingleDISPLAY.Technology of the first mobile model in the seriesUnlike the six smaller models, the UF450m is designed for 400 V and 3 x 230 V without neutral conductor at 50/60 Hz, and the power consumption is around 5,800 watts. In the 449 litre interior, an electronically controllable air turbine distributes the heat, and an exhaust air flap admixes preheated fresh air. The ControlCOCKPIT SingleDISPLAY controls the temperature between 20 and 300 °C with a setting accuracy of 0.1 or 0.5 °C, plus forced air circulation fan speed and programme run time, and SetpointWAIT delays the start of the keep-warm time until the setpoint temperature is reached. The safety equipment includes an adjustable electronic temperature monitoring, a mechanical temperature limiter of protection class 1 according to DIN 12880 that switches off the heating around 20 °C above the maximum cabinet temperature, and a self-diagnosis system for fault finding.Choosing within the UF-m seriesThe housing measures 1,224 x 1,247 x 784 mm, plus 56 mm in depth for the door handle, and the net weight is around 161 kg. At the installation site, a distance of at least 15 cm to the wall and at least 5 cm at the sides must be kept. The UF750m, with 749 litres, offers more volume, and the UF260m, with 256 litres, is one size smaller. The sister model UF450mplus is available for two redundant sensors and two displays. As a laboratory device without classification as a medical device, there is the Memmert universal oven UF450.Typical applicationsAs a Class I medical device, the Memmert universal oven UF450m is intended exclusively for physiotherapeutic applications with fango, silicate and APS packs.Heating of fango packs for physiotherapeutic useHeating and keeping warm of silicate packsHeating and keeping warm of APS packsTechnical detailsSetting temperature range20 to 300 °CWorking temperature rangemin. 10 °C above room temperature to 300 °CTemperature setting accuracyup to 99.9 °C: 0.1 °C, from 100 °C: 0.5 °CTemperature sensor1x Pt100, DIN class A, 4-wire measurementInternal volume449 lInternal dimensions (W x H x D)1,040 x 720 x 600 mm (depth minus 39 mm for the fan)External dimensions, housing (W x H x D)1,224 x 1,247 x 784 mmNet weightapprox. 161 kgGross weight (packed)approx. 227 kgPackaging dimensions (W x H x D)1,330 x 1,440 x 1,050 mmConnection400 V and 3 x 230 V without neutral conductor, 50/60 Hz, approx. 5,800 WShelves, maximum8Shelves in scope of delivery2Max. load, device300 kgMax. load per shelf30 kgMaterial, interiorStainless steel, 4-sided all-round heatingMaterial, housingTextured stainless steel, galvanised sheet steel rear panelControlControlCOCKPIT SingleDISPLAY, PID microprocessor controller, TFT colour graphic displayInstallationmobile and lockable on castorsPermissible ambient temperature5 °C to 40 °CPermissible humiditymax. 80 % rh, non-condensingMedical device classificationClass I under Regulation (EU) 2017/745Intended purposeHeating/keeping warm of fango, silicate and APS packs in physiotherapyMarkingsCE, VDE, UL markOther sizes in the seriesThe UF-m series comprises nine sizes between 32 and 1,060 litres of internal volume, all with ControlCOCKPIT SingleDISPLAY and an identical intended purpose for physiotherapy.ModelInternal volumeSetting temperatureDisplayUF30m32 l+20 to +300 °CSingleDISPLAYUF55m53 l+20 to +300 °CSingleDISPLAYUF75m74 l+20 to +300 °CSingleDISPLAYUF110m108 l+20 to +300 °CSingleDISPLAYUF160m161 l+20 to +300 °CSingleDISPLAYUF260m256 l+20 to +300 °CSingleDISPLAYUF450m (this page)449 l+20 to +300 °CSingleDISPLAYUF750m749 l+20 to +300 °CSingleDISPLAYUF1060m1,060 l+20 to +300 °CSingleDISPLAYThe sister model with two displays and redundant sensors is the UF450mplus.

The Memmert UF450mplus universal oven is not a laboratory drying oven for general use, but a Class I medical device in accordance with Regulation (EU) 2017/745, intended for the heating and keeping warm of fango, silicate and APS packs in physiotherapy. Technically, it is based on the same housing as the UF450plus laboratory/industrial cabinet, with an internal volume of 449 litres, a temperature range of 20 to 300 °C, TwinDISPLAY with two redundant Pt100 sensors, HeatBALANCE and AutoSAFETY; however, it is intended for medical use rather than general laboratory and industrial applications.Forced air circulation with redundant temperature measurement for physiotherapyThe UF450mplus’s air turbine, which is electronically controllable in 10 % increments, actively distributes heat throughout the interior and achieves a working temperature range from 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; if one fails, the second automatically takes over its function. The setting accuracy is 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C onwards, which is important for the uniform heating of pack material to the temperature intended for use on the patient. Preheated fresh air is introduced via an electronically adjustable exhaust air flap.ControlCOCKPIT TwinDISPLAY: HeatBALANCE and AutoSAFETYThe UF450mplus is controlled via the ControlCOCKPIT TwinDISPLAY, which features two high-resolution TFT colour graphic displays. The HeatBALANCE function allows 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, an important safeguard when preparing pack material for use on patients. Programmes are programmed, managed and transferred via the Ethernet interface or USB port using the AtmoCONTROL software.Capacity and connections of the Memmert UF450mplus universal ovenThe interior measures 1,040 x 720 x 600 mm and accommodates 2 electropolished stainless steel grid shelves as standard; up to 8 shelves are possible in total. A total load of up to 300 kg and up to 30 kg per shelf are permitted, sufficient for several batch loads to be processed in parallel. The external dimensions of the cabinet are 1,224 x 1,247 x 784 mm, with a net weight of approximately 161 kg. 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 UF450mplus is connected to a 400 V three-phase supply and 3 x 230 V without a neutral conductor at 50/60 Hz and has a power consumption of approximately 5,800 W; it is mounted on castors and can be moved and locked in place.Class I medical device: Intended use and classificationThe UF450mplus is classified as a Class I medical device in accordance with Regulation (EU) 2017/745, with the intended purpose of heating and maintaining the temperature of fango, silicate and APS packs in physiotherapy. This classification distinguishes it fundamentally from the technically identical laboratory and industrial unit, the Memmert UF450plus universal oven, which is intended for drying, tempering and material testing, but has no medical intended use. The mplus model described here is intended for a physiotherapy practice, not the general-purpose laboratory unit.Difference between physiotherapy device and laboratory/industrial cabinetAnyone looking for a unit for drying, tempering or material testing processes in a laboratory or industrial setting should consider the Memmert UF450plus universal oven; it is technically largely identical but does not have a medical intended purpose. The UF450mplus described here is intended exclusively for the physiotherapy application specified in its intended use. The units are indistinguishable in appearance.Safety according to DIN 12880, enhanced by AutoSAFETYIn addition to the adjustable electronic temperature monitoring and AutoSAFETY, the UF450mplus features a mechanical temperature limiter of protection class 1 according to DIN 12880, which switches off the heating when the temperature reaches approximately 20 °C above the maximum cabinet temperature. The display also allows the user to select either an adjustable temperature monitor of protection class 3.1 or an adjustable temperature limiter of protection class 2. An integrated self-diagnostic system assists with fault finding, and three freely selectable temperature values can be calibrated. According to the data sheet, the unit bears the CE, VDE and UL marks.Installation, operation and disposalFor operation, a minimum clearance of 15 cm from the wall and a minimum clearance of 20 cm from the ceiling must be maintained; a minimum clearance of 5 cm is sufficient on the sides from the wall or an adjacent unit. Installation is permitted 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 cabinet is designed for overvoltage category II and pollution degree 2; it must only be transported in an upright position. Thanks to its castors, the UF450mplus can still be repositioned within these specifications at a later date, for example when treatment rooms are being redesigned. As an electrical appliance, it is subject to the Electrical and Electronic Equipment Act at the end of its service life and must not be disposed of with household waste; see Regulatory information below.Typical applicationsAs a Class I medical device, the Memmert UF450mplus universal oven is intended exclusively for physiotherapeutic applications involving fango, silicate and APS packs.Heating of fango packs for physiotherapy applicationsHeating and maintaining the temperature of silicate packsHeating and maintaining the temperature of APS packsPhysiotherapy practices, rehabilitation centres and clinics offering the relevant treatmentsWhich device for which intended purposeThe UF450mplus is supplied with 2 electropolished stainless steel grid shelves; the cabinet is designed to accommodate up to 8 shelves. The investment decision here is primarily a question of intended use, not of features: the UF450mplus medical device is intended for a physiotherapy facility with a specific intended use. On the other hand, anyone looking for a laboratory or industrial unit for drying, tempering or materials testing is better served by the Memmert UF450plus universal oven, which is of identical construction but is not classified as a medical device. An additional Pt100 sensor is available as an option for extra over-temperature monitoring. For continuous data logging, a USB-to-Ethernet adapter and AtmoCONTROL software licences, including the AtmoCONTROL FDA version for 21 CFR Part 11, are available. For standard-compliant applications, we arrange calibration, IQ/OQ/PQ and maintenance services, including DAkkS calibration on request.Frequently asked questions before purchaseFor what purpose is the UF450mplus intended?As a Class I medical device in accordance with (EU) 2017/745 for heating and maintaining the temperature of fango, silicate and APS packs in physiotherapy.Can I also use the UF450mplus for laboratory drying?Technically, it is of identical construction to the Memmert UF450plus universal oven; however, its intended use as a medical device relates exclusively to physiotherapy applications.
