Chiller for open circuit
Code No.： 0031810-000
The line-up of open circuit chillers can be chosen according to the required capacity and temperature control accuracy. Precise temperature control type.
Applications●Circulation into temperature control water bath for inspection samples.
● Temperature control for culturing apparatus and analytical instruments[option].
For open circuit machine use for circulate mainly to water bath.Circulation system for open circuit is used mainly for preparing constant temperature chamber. It is optimum for control temperature of sample.
Closed circuit is also available as an option
Use optional port tank and the thermal insulation water tank for circulation into scientific instrument (closed circuit circulation).
Even for objects with high piping resistance such as rotary evaporators, circulation can be easily started with the built-in priming pump.
Thermograph and safety device actuation signal can be used.Output of thermograph, safety device actuation signal and optional external sensor. Programmed control is available by using optional program unit.

|(*1)When using enough water and agitation inside water bath is good. Temperature regulation accuracy may vary depend on circulating fluid, setting temperature, environmental temperature, bath volume and circulating flow.|
|(*2)When circulating fluid is +10ºC, 50Hz.|
|(*3)Allowance of voltage variation is ±5% for AC 100V.|
|●Environmental temperature for this product is +5ºC - +30ºC. When using at above +30ºC, cooling capacity may reduce. Lid of water bath may needed depend on bath shape and setting temperature.|
|●Please do not use pure water or distilled water. These may cause breakdown of machine.|
|●Please use heating medium when setting below +7ºC.|
|●External program control is possible by using optional program unit only in the case below 40ºC.|
