Product Description
HayWHNKN Refrigerating Air Dryer

The humid and high temperature compressed air flows into the front cooler after the heat exchange into the heat exchanger and the cold air discharged from the evaporator, so that the temperature of the compressed air into the evaporator is reduced.
Product Parameters

30C Refrigerating Dryer Air Compressor:220V 1200W Product size:31.5*17.3*31.5inch
20C Refrigerating Dryer Air Compressor: 110V 1000W Product size:29.5*16.5*28.7inch
Operation Method:
1. Check whether the refrigeration system pressure of the machine is normal. Check that the ball valve at the front of the automatic drainage valve is open. 2. Send the power supply to the control box, press ON/OFF button switch ON button, machine contactor suction, compressor operation. At this time, the refrigerant low pressure gauge pointer should indicate that it is in the range of 60~85Psig. If the load exceeds this range, adjust it. 3. After the compressor runs smoothly, the pressure of the refrigerant high pressure gauge rises to between 120 and 240psi. When the high pressure of the refrigerant is higher than this range, check whether the heat dissipation of the condenser is good, and whether the inlet temperature of the air compressor and the ambient temperature are too high. When the antifreeze switch is lower than 140Psig, the condensing fan stops running to increase the pressure to ensure the normal operation of the machine. If the machine is operated at low pressure for a long time, check whether the refrigeration system leaks. 4. Please turn off the air compressor before shutting down. After turning OFF the air compressor, press the ON/OFF switch to turn off the power supply of the machine.
