Heating & Cooling Circulator

High and low temperature integrated machine, also known as high and low temperature circulation device, cold and hot integrated machine, refrigeration and heating integrated machine, etc., is a temperature control device that integrates refrigeration and heating. The liquid circulation of the entire system is sealed, and the heat transfer fluid is not easily evaporated and oxidized at high temperatures, and is not easily absorbed by moisture in the air at low temperatures, thus extending the service life of the heat transfer fluid; The system is equipped with an expansion container, which is insulated from the liquid circulation and does not participate in the liquid circulation. Therefore, regardless of whether the temperature of the liquid circulation is high or low, the medium in the expansion container is below 60 ℃. Commonly used in double-layer glass reactors, stainless steel sandwich reactors, and other equipment with sandwich layers that require high and low temperature use
