If direct current is supplied to the Peltier device (thermo-module), heat is transferred inside the device, and one face generates heat and increases temperature while the other face absorbs heat and decreases temperature. Therefore, changing the direction of the current supplied to the Peltier device (thermo-module) can achieve heating and cooling operation. This method has a fast response and can shift quickly between heating and cooling, so temperature can be controlled very precisely. Water-cooled Air-cooled Series HEC-A Series HEC-W �� Compliant with safety standard for medical equipment IEC 60601-1 (Air-cooled/HEC002-A series) �� Power supply: Applicable to 100 V to 240 V (Air-cooled/HEC-A series, Water-cooled/HEC001-W, HEC003-W) �� Suitable to fluorinated fluids (FluorinertTM FC-3283, GALDENR HT135) (Water-cooled/HEC006-W, HEC012-W) �� Compatible with ethylene glycol 20% (Water-cooled/HEC001-W, HEC003-W) Principle of Peltier Device (Thermo-module) Learning Control Function (Temp. control by external temperature sensor) This function adjusts the fluid temperature to the set value with an automatic offset setting. Set the external temperature sensor at the circulating fluid inlet located just in front of the heat source, which allows the Thermo-con to sample the fluid temperature. This function is effective when automatically adjusting for heat exhaust from piping, etc. If the external temperature sensor is installed directly on the heat source, the learning control function may not work property due to large heat volume or large temperature difference. Be sure to install the sensor at the circulating fluid inlet. 1380
