How the heat and cold unit works: the pump drives the heat transfer medium (usually water or oil) from the tank with the built-in heater to the temperature control device and back from the temperature control device to the tank. The controller adjusts the temperature of the thermal fluid according to the temperature of the thermal fluid measured by the temperature sensor or the internal temperature of the temperature control device.
Generally, water control temperature range is low, oil control temperature range is high. Water type of working temperature is 90 ℃, pressure water type of working temperature is 160 ℃ ~ 180 ℃, oil type is used to working temperature of 150 ℃ or more occasions, the highest working temperature is 350 ℃.
