The HR series heating and cooling circulators produced by wuxi guanya can provide the circulation devices of cold source and heat source, with a wide range of work. They are used in pharmaceutical, chemical, biological and other industries, providing heat source and cold source for the reaction kettle and tank, and also can be used for heating and cooling of other equipments.
The whole liquid circulation is closed with an expansion container. The expansion container and the liquid circulation are adiabatic and do not participate in the liquid circulation. They are just mechanically connected, no matter whether the liquid circulation temperature is high or low.

Technical feature of heating Kühlung translator
1.Wide range of working temperature, and at the same time have heating refrigeration function, temperature range: 25 ℃ ~ 200 ℃.
2.The controller with two LED displays can display both the set temperature and the actual value, as well as the overtemperature alarm value.
3.High efficiency, quick filling and simple.
4.Ensure rapid cooling at high temperature; Can achieve 200 degrees to minus 20 degrees continuous temperature control.
5.The circulation management is completely closed, without oil mist and water absorption, which ensures the safety of the experiment and the life of the thermal conductivity.
6.Have the function of self-diagnosis; Refrigerator overload protection; High pressure switch, overload relay, thermal protection device and other safety functions.
7.Control the temperature of thermal medium, the whole process of heating and cooling is using the same thermal medium.
8.High lift design, heat-conducting medium that can satisfy the long-distance transmission
