High and Low-temperature Integrated Circulator

Heating and Refrigeration Circulator – HR-70 Series

The whole liquid circulator is enclosed, and provided with an expansion container. The expansion container is insulated from liquid circulation, does not take part in liquid circulation, and is only connected mechanically. In spite of high or low liquid circulation temperature, the medium in the expansion container is lower than 60℃.

The whole liquid circulator is an enclosed system, and does no absorb water vapor at low temperature or generate oil mist at high temperature. The heat transfer oil has extremely wide operating temperature range; there are no mechanical and electronic valves used in the whole circulation system.
