For open circuit machine used for mainly circulating to the water bath.
Circulation system for open circuit is used mainly 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 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 the optional program unit.

|(*1) When using enough water and agitation inside water bath. Temperature regulation accuracy may vary depending on the circulating fluid, setting temperature, environmental temperature, bath volume, and circulating flow.|
|(*2) When circulating fluid is +10℃, 50 Hz.|
|(*3) Allowance of voltage variation is ±5% for AC 100 V.|
|•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℃.|
|•External program control is possible by using the optional program unit only in the case below 40℃.|
