High and low temperature circulating equipment

Function: high and low temperature circulation device. The liquid circulation of the whole system is closed. The system is equipped with an expansion container. The expansion container and the liquid circulation are insulated and do not participate in the liquid circulation. It is just a mechanical connection. No matter whether the temperature of the liquid circulation is high or low, the medium in the expansion container is less than 60 ℃. The whole liquid circulation is a closed system. There is no absorption of water vapor at low temperature and no oil mist at high temperature. The heat transfer oil can work at a wide range of temperatures; The same machine and the same heat conducting medium can realize temperature control from - 60 ℃ to 200 ℃.
