The refrigerated dryer mainly consists of three parts: heat exchange system, refrigeration system, and electrical control system;
The compressed air first enters the pre cooler for heat exchange, removing a portion of the thermal energy, and then enters the cold and hot air exchanger, where it exchanges heat with the cold air that has been cooled to the dew point from the evaporator, further reducing the temperature of the compressed air;
Afterwards, the compressed air enters the evaporator and undergoes heat exchange with the refrigerant. The temperature of the compressed air drops to 2-10 ° C, and the moisture in the air precipitates at this temperature. After being separated by a gas water separator, it is discharged through an automatic drain;

And the dry low-temperature air enters the cold and hot air exchanger for heat exchange, and is output after the temperature rises.
