Chiller for open circuit
Code No.： 0031813-000
【discontinued】The line-up of chillers for open circuit can be chosen according to the required capacity and temperature control accuracy. Closed circuit is also available as an option.
Applications●Circulation into temperature control water bath for inspection samples
●Temperature control for culturing apparatus and analytical instruments is available as an option
FeaturesThis product has been discontinued.
For open circuit machine used for mainly circulating to the water bath.
Circulation system for open c i r cui t i s u sed mainl y for preparing a constant temperature chamber. It is optimum for controlling the temperature of the sample.
Closed circuit is also available as an option.
Use the optional port tank and the thermal insulation water tank for circulation into scientific instruments (closed circuit circulation). Even for obj ect s wi th hi g h p i p ing resistance such as rotary evaporators, circulation can be easily started with the built-in priming pump.

|•Environmental temperature for this product is +5℃ to +30℃. When using at above +30℃, the cooling capacity may be reduced. The Lid of the water bath may be needed depending on the bath shape and|
|the setting temperature.|
|•Please do not use pure water or distilled water. These may cause breakdown of the machine.|
|•Please use heating medium when setting below +7℃.|
