air dryer for compressor

Air Dryer (working principle) : The working principle of refrigerated dryer is composed of heat exchange system, refrigeration system and electrical control system. Compressed air first enters the pre-cooler for gas-gas or gas-water heat exchange, removing part of the heat energy, and then enters the cold and hot air exchanger, and has been cooled from the evaporator to the pressure dew point for heat exchange, so that the temperature of compressed air is further reduced. After that, the compressed air enters the evaporator and conducts heat exchange with the refrigerant. The temperature of the compressed air drops to 0-8℃. The moisture in the air is separated out at this temperature and discharged through the automatic drainer after being separated by the gas-water separator. The dry low temperature air enters the cold and hot air exchanger for heat exchange and output after the temperature rises. Freeze Dryer (hereinafter referred to as Air Dryer) is a method of first fr…
