IKA RC 2 GREEN control Circulation Chiller, R290, 800 W Cooling Capacity, WiCo Wireless Controller, 0025006638

Product information "IKA RC 2 GREEN control Circulation Chiller, R290, 800 W Cooling Capacity, WiCo Wireless Controller, 0025006638"

If you have been searching for the IKA RC 2 control recirculating chiller and have been redirected here: the previous model was discontinued on 31 July 2026; the IKA RC 2 GREEN control recirculating chiller is the successor model designated by IKA. It delivers up to 800 watts of cooling capacity at 20 degrees Celsius, operates using the natural refrigerant R290 and supplements the cooling function with a PID controller featuring a TFT display, as well as a WiCo wireless controller for programmable temperature profiles. As an external cooling source, it cools rotary evaporators, laboratory reactors and other equipment fitted with heat exchangers.

Successor to the IKA RC 2 control: what’s changing

IKA has discontinued production of the RC 2 control as of 31 July 2026 as part of the portfolio transition to natural refrigerants. IKA guarantees the availability of spare parts and repair services for all discontinued units in this series for at least 10 years. The RC 2 GREEN control retains the design and connection dimensions virtually unchanged and is the direct successor. Compared with its predecessor, the refrigerant, cooling capacity and pump capacity have changed; in terms of temperature stability, the specified value for the successor is numerically higher than that of its predecessor. The following table compares both series with their respective documented values:

FeatureRC 2 control (predecessor)RC 2 GREEN control (this product)

Max. flow rate18 l/min21 l/min
Temperature stability (DIN 12876)±0.05 K±0.15 K
Weight28.5 kg26.5 kg

Unlike the RC 2 basic, the RC 2 control is no longer in stock; it is no longer possible to order this model with R134a. If you are looking for a cooling-only unit without a WiCo wireless controller, using the natural refrigerant R290, the IKA RC 2 GREEN basic is the right choice.

Cooling capacity and control

At 20 degrees Celsius, the RC 2 GREEN control delivers up to 800 watts of cooling capacity; at 10 degrees Celsius, this is 700 watts; at 0 degrees Celsius, 500 watts; at minus 10 degrees Celsius, 400 watts; at minus 20 degrees Celsius 200 watts and at minus 30 degrees Celsius 90 watts. The operating temperature range thus extends from minus 30 degrees Celsius to room temperature; with an external heater, the bath can also be used up to 70 degrees Celsius. Unlike the RC 2 GREEN basic, a PID controller with a TFT display manages the temperature control here; internally, a 3-point calibratable PT100 sensor takes measurements, the display resolution is 0.01 Kelvin, and the setting accuracy for the setpoint temperature is 0.1 Kelvin. According to DIN 12876, a temperature stability of ±0.15 Kelvin is specified; the comparative value for the predecessor model can be found in the table in the section on the successor model above.

Refrigerant R290: Safety group A3 and installation instructions

The RC 2 GREEN control also operates with the natural refrigerant R290 (propane), charged with 69 grams at a maximum permissible pressure of 21 bar. According to DIN EN 378-1, R290 belongs to safety group A3 and is therefore flammable; according to an IKA leaflet on the refrigerant, the GWP value of R290 is 3. According to the operating instructions, a minimum room volume of 9 cubic metres and a clearance of at least 20 centimetres in front of and behind the unit must be maintained to ensure safe operation, so that no flammable mixture can form even in the event of a complete leak of the refrigerant charge. Practical note: For ongoing operation, as is standard practice for laboratory equipment using flammable refrigerants, it is recommended to install the unit in a sufficiently ventilated location with no open ignition sources in the immediate vicinity.

WiCo wireless controller: wireless operation with temperature programmes

In addition to the built-in TFT display, the RC 2 GREEN control features a wireless controller (WiCo), which displays the relevant process parameters wirelessly and facilitates operation of the unit. Up to 10 temperature programmes, each with 10 steps, can be freely programmed in the WiCo; a timer/counter function is also available. Both the internal probe and an external PT100 probe connected via the LEMO socket can be calibrated using the 3-point calibration method.

Selection guide: RC 2 GREEN control or RC 2 GREEN basic

The RC 2 GREEN control and RC 2 GREEN basic share the same refrigeration circuit, cooling capacity and pump; the difference lies in the control system and operation:

FeatureRC 2 GREEN control (this product)RC 2 GREEN basic
Cooling capacity at 20 °C800 W800 W

Display resolution0.01 K0.1 K
External PT100 connection (LEMO)yesno
WiCo wireless controller with programmesyesno
Weight26.5 kg25.5 kg

If you wish to connect an external temperature sensor, programme temperature profiles or monitor the unit wirelessly, the RC 2 GREEN control is the right choice for you. If operating the unit directly without WiCo and an external sensor connection is sufficient, the IKA RC 2 GREEN basic is the slimmer and lighter alternative.

Differentiation within the IKA recirculating chiller range

Within the IKA temperature control unit range, the RC 2 GREEN control is the best-equipped dedicated cooling solution. Those looking for a more compact entry-level solution with lower cooling capacity will find it in the IKA RC 2 lite, which delivers up to 400 watts at 20 degrees Celsius. Those who need to actively heat as well as cool will find what they are looking for in the IKA HRC 2 GREEN control or, without the WiCo wireless controller, in the IKA HRC 2 GREEN basic; both are identical in construction to the RC 2 GREEN series but feature an additional heating function.

Typical applications

As an external cooling source with a closed circuit and programmable temperature control, the RC 2 GREEN control is suitable, amongst other things, for:

  • Cooling rotary evaporators, such as the IKA RV 10 digital V-C or the IKA RV 3 V-C
  • Cooling reflux condensers during syntheses and extractions with recurring temperature profiles
  • As a cooling source for laboratory reactors, double-walled vessels and other equipment with heat exchangers
  • Processes with external PT100 measurement directly on the test sample

Connection, installation and ongoing operation

The integrated pressure/suction pump achieves a maximum flow rate of 21 l per minute at a maximum pump pressure of 0.5 bar on the pressure side and 0.25 bar on the suction side, connected via M16x1 threaded connections. The internal bath has a capacity of between 1.4 and 4.0 l. In addition to RS232 and Micro-USB, a LEMO socket provides a third connection for an external PT100 temperature sensor. The permissible ambient temperature range is 5 to 32 degrees Celsius at a maximum relative humidity of 80 per cent; the housing is protected to IP 21 in accordance with DIN EN 60529.

Regulatory information

As an electrical appliance, the RC 2 GREEN control is subject to the German Electrical and Electronic Equipment Ordinance (ElektroG) and is registered with the EAR Foundation under WEEE registration number DE 66784213. At the end of its service life, the appliance must not be disposed of with household waste, but must be taken to a separate collection point for waste electrical and electronic equipment. The R290 refrigerant contained in the refrigeration circuit must be professionally recovered by an authorised refrigerant recovery company prior to disposal.

Frequently asked questions about the RC 2 GREEN control

Is the RC 2 GREEN control the successor to the RC 2 control?
Yes. IKA ceased production of the RC 2 control on 31 July 2026; its successor is the RC 2 GREEN control, which uses the natural refrigerant R290 and, according to IKA, offers approximately double the cooling capacity compared with the previous generation of units.

Is R290 hazardous in everyday laboratory use?
R290 (propane) is a natural but flammable refrigerant classified in safety group A3 according to DIN EN 378-1. According to the operating instructions, the minimum room size of 9 cubic metres specified by the manufacturer and the clearance of at least 20 centimetres around the unit ensure that, even in the event of a complete leak, no flammable mixture will form.

How does the RC 2 GREEN control differ from the RC 2 GREEN basic?
Both share the same refrigeration circuit, cooling capacity and pump. The RC 2 GREEN control also features a PID controller with a TFT display, a LEMO socket for an external PT100 sensor and the WiCo wireless controller; as a result, it is around 1 kilogram heavier.

Is there still an R134a unit from this series in stock?
No, there is no longer any stock of the RC 2 control. An alternative featuring the non-flammable refrigerant R134a and 400 watts of cooling capacity, though without the WiCo wireless controller, is the IKA RC 2 basic, which remains available from stock.

Can an external temperature sensor be connected?
Yes, an external PT100 sensor can be connected via the LEMO socket and calibrated using a 3-point calibration, for example to take measurements directly within the test specimen rather than in the unit’s bath.

IKA Inkubationsschüttler KS 4000 ic control (mit Kühlung)
IKA KS 4000 ic control Incubating Shaker (with Cooling), 0003510100
Herstellernummer: 0003510100

Anyone who lets cell cultures or microbiological samples shake unattended overnight needs temperature control that also works below room temperature. The IKA KS 4000 ic control combines an orbital shaking motion with PID-controlled heating up to 80 degrees Celsius and a built-in cooling coil. Together with an externally connected circulation chiller, the 90 litre internal chamber reaches temperatures down to room temperature minus 10 degrees. Without this chiller, the device works as an incubating shaker with heating, entirely without active cooling.PID control from minus 10 to 80 degrees CelsiusTwo PT1000 temperature sensors and an integrated PID controller hold the set temperature with a setting accuracy of 0.1 kelvin. With a vessel containing 0.5 litre of water, 22 degrees room temperature and 37 degrees set temperature, the control accuracy is ±0.5 kelvin and the temperature stability is ±0.05 kelvin. With 0.2 litre of water at 25 degrees room temperature and 37 degrees set temperature, the stability falls to ±0.1 kelvin. Spread over five vessels of 0.5 litre each, the homogeneity in the interior is ±0.5 kelvin. A large LED display shows speed and temperature, and an additional connection socket in the working space takes a further PT1000 sensor, for example the supplied PT 1000.60 made of stainless steel.Cooling coil and external circulation chiller belong togetherThe KS 4000 ic control has no compressor of its own and no refrigerant circuit of its own. The built-in cooling coil needs an externally connected circulation chiller, and IKA names models such as the RC 2 lite, the RC 2 basic or the RC 2 control for this. LT Laborhandel also carries the IKA RC 5 control for this purpose, with 1400 watt cooling capacity down to minus 30 degrees. Without a connected chiller, the temperature range remains limited to room temperature up to 80 degrees. Anyone who knows from the outset that work will only be done above room temperature saves the chiller and chooses the otherwise identical KS 4000 i control (ident no. 0003510000) without a cooling coil.20 kilograms shaking load at 20 millimetre orbitThe orbital motion has a shaking orbit of 20 millimetres and carries up to 20 kilograms of shaking material including attachment. The speed ranges from 10 to 500 revolutions per minute, adjustable in steps of 1 rpm, with a deviation of ±5 rpm. The motor draws 82 watts and delivers 24 watts, designed for a duty cycle of 100 per cent. The electronic timer covers 0 to 999 hours, optionally in timer or continuous operation, with a 7-segment LED display for the remaining time.Safety and everyday operationIn the event of a fault, the device switches off automatically, and likewise when the hood is opened during operation. The controls have an antimicrobial coating, and a drip tray with a drain hose at the back of the device catches spilled liquid. Via the RS-232 interface, the KS 4000 ic control can be connected to the laboratory device software labworldsoft, for documenting temperature, speed and time. The housing is made of powder-coated sheet steel, the front foil of polyester.Typical applicationsMicrobiological cultures with a cooling requirement below room temperatureCell cultivation with tight tolerances for temperature stability and homogeneityUnmonitored shaking operation overnight or over the weekendDocumented temperature control via labworldsoft in quality-assured laboratoriesTechnical detailsType of motionorbital, shaking orbit 20 mmPermissible shaking load (incl. attachment)20 kgSpeed range10 to 500 rpm, steps 1 rpm, deviation ±5 rpmMotor power input / output82 W / 24 WHeating power1000 WTemperature range (with external circulation chiller)Room temp. -10 °C to 80 °CControl accuracy / stability (0.5 l, 37 °C)±0.5 K / ±0.05 KHomogeneity (5 vessels 0.5 l, 37 °C)±0.5 KTimerelectronic, 0 to 999 h, timer and continuous operationWorking area internal chamber (W x H x D)440 x 440 x 352 mmTotal volume internal chamber90 lMaterial housing / front foilPowder-coated sheet steel / polyester foilRS 232 interfaceyesProtection classIP 30 (DIN EN 60529)Dimensions (W x H x D)580 x 520 x 750 mmWeight55 kgConnected load230 V, 50/60 Hz, 1120 W, fuse 2x T10A 250VScope of delivery1 x KS 4000 ic control1 x PT 1000.60 temperature sensor, stainless steel4 x clamping screws short (for fixing the attachment)2 x clamping screws long (for fixing the attachment)Attachments such as the universal attachment or retaining clips are not included and must be ordered together with the device to suit the application. An external circulation chiller for the cooling function is likewise not part of the scope of delivery.Selection guide and serviceIf you need a smaller internal chamber, the KS 3000 ic control (ident no. 0003940100) offers the same cooling principle with a built-in cooling coil, but only 50 litres of volume, a shaking load of up to 7.5 kilograms and an additional USB-B interface. IKA grants a manufacturer's warranty of 2 years for the KS 4000, extended to 5 years with registration at ika.com/register within 90 days of purchase. As an electrical device, the KS 4000 ic control falls under the WEEE directive and must not be disposed of with household waste at the end of its life. Via the procurement service of LT Laborhandel, circulation chillers, attachments and further accessories can be ordered together to suit the application.

Herstellernummer: 0003940100

It is not possible to maintain the temperature of samples below room temperature using a heater alone. The IKA KS 3000 ic control therefore has a built-in cooling coil with connections for an external cooling unit; IKA cites the RC 2 basic or RC 2 control as examples. With cooling, the temperature range extends from room temperature minus 10 K to 80 °C, provided the inlet temperature is above 3 °C. The incubation shaker performs circular shaking with a 20 mm stroke at 10 to 500 rpm and can hold up to 7.5 kg.Heating and coolingAn integrated PID control system operates with two PT-1000 sensors; the heating power is 1000 W. The setpoint temperature is adjusted and displayed in increments of 0.1 K. With a sensor in the vessel, the control accuracy is ±0.5 K (1 vessel containing 0.5 l of water, 22 °C room temperature, 37 °C). Temperature stability is ±0.05 K (1 vessel containing 0.5 l, room temperature 25 °C, 37 °C), whilst temperature homogeneity across five vessels, each containing 0.5 l, is ±0.5 K. There is a connection socket for an additional sensor in the working chamber. A stainless-steel PT 1000.80 is included in the Scope of delivery.Interior, hood and safety featuresThe inner chamber measures 330 x 330 x 258 mm and has a volume of 50 l. The lid is made of PMMA, whilst the housing is made of powder-coated sheet steel. The unit stops automatically when the lid is opened and switches itself off in the event of a fault. The control elements have an antimicrobial coating to reduce bacteria. A drip tray with a drain hose at the rear collects any liquid. Speed and time are shown on a large LED display. The timer ranges from 1 second to 999 hours; alternatively, the unit can run continuously.Typical applicationsShaking temperature-controlled samples for hours in unattended operationIncubation at a constant temperature, for example at 37 °CTemperature control below room temperature with a connected cooling unitDocumented runs via RS 232, USB-B and labworldsoftShaking of vessels of various sizes using clamps or a universal adapter, up to 7.5 kgWith or without a cooling coilIf you only need to heat from room temperature plus 5 K, you can opt for the KS 3000 i control. It has the same chamber, the same speed and the same shaking weight, but weighs 35 kg instead of 37 kg. For heavier batches requiring a 20 kg shaking load and a 90-litre chamber volume, the KS 4000 i control is available.ModelTemperature rangeShaking weightInternal chamberWeightKS 3000 ic control (this unit)Room temperature minus 10 K to 80 °C (with cooling)7.5 kg50 l37 kgKS 3000 i controlRoom temperature plus 5 K to 80 °C7.5 kg50 l35 kgKS 4000 i controlRoom temperature plus 5 K to 80 °C20 kg90 l50 kgTechnical detailsMotion and strokecircular, 20 mmShaking weight including attachmentup to 7.5 kgMotor power input / output45 W / 10 WRotational speed10 to 500 rpm in 1-rpm increments, deviation 1 %Timer1 s to 59,940 min, 7-segment LED, continuous operation possibleDuty cycle100 %heating power1,000 WTemperature range (flow temperature above 3 °C)Room temperature minus 10 K to 80 °CSetpoint temperature adjustmentin increments of 0.1 KControl accuracy with sensor±0.5 K (1 vessel containing 0.5 l of water, room temperature 22 °C, 37 °C)temperature stability±0.05 K (1 vessel, 0.5 l, ambient temperature 25 °C, 37 °C), ±0.1 K (0.2 l water, ambient temperature 25 °C, 37 °C)Temperature homogeneity±0.5 K (5 vessels, 0.5 l, ambient temperature 25 °C, 37 °C)CoolingBuilt-in cooling coil with connections for external coolingInternal chamber (W x H x D)330 x 330 x 258 mm, 50 lMaterialsHousing: powder-coated sheet steel, cover: PMMA, front panel: painted ABS, front film: polyesterInterfacesRS 232, USB-BDimensions (W x H x D)465 x 430 x 695 mm, 875 mm high with the cover openWeight37 kgOperating environment15 to 32 °C, up to 80 % relative humidityProtection classIP 30 (DIN EN 60529)Mains connection230 V, 50/60 Hz, 1120 WScope of delivery1 x IKA KS 3000 ic control incubation shaker1 x PT 1000.80 temperature probe, stainless steel4 x clamping screws, short1 x USB A-to-B cableLids and the external cooling unit are not included in the Scope of delivery.
