Hermetic High Temperature Heating Circulator is equipped with an expansion tank, and the expansion tank and the circulation system are adiabatic. The thermal medium in the vessel does not participate in the system circulation, but is only mechanically connected. No matter the thermal medium in the circulation system is high or low, the medium in the expansion tank is always lower than 60°.
The whole system is hermetic system. With high temperature, it will not cause oil mist; with low temperature,it will not absorb moisture in the air. In high temperature operation, the pressure of the system will not rise, and in low temperature operation, the system will be supplemented thermal medium automatically.
