High and low temperature heating and cooling cycle pump

The explosion-proof high and low temperature heating and cooling cycle pump is equipped with a fully enclosed heat transfer medium for the entire circulation system. The circulation system is equipped with a liquid expansion container, which is an independent system from the liquid circulation. The expansion container does not participate in the liquid circulation, but is only mechanically connected. Even under high temperature operation, the thermal conductivity medium in the expansion container will not exceed 50 degrees.
