Page 4: Description
AIR DRYER INSTRUCTION MANUAL DESCRIPTION Function Compressed air enters the air-to-air heat exchanger and is pre-cooled by the chilled outgoing air. The air then enters the air-to-refrigerant heat exchanger where it is further cooled by the refrigeration system. As the air is cooled, water vapor condenses into liquid droplets. -

AIR DRYER INSTRUCTION MANUAL condensed moisture, oil and solids are separated from the compressed air and discharged from the system by an automatic condensate drain trap. The cold compressed air, enters the shell side of pre-cooler. By removing heat from the incoming air, the outgoing air is reheated. - Page 6 AIR DRYER INSTRUCTION MANUAL the vibration of the compressor from interfering with the dryer’s operation. 3.Mount dryer on firm level surface. 4.Automatic drain outlet should be connected to the plant drainage system in order to prevent condensate from polluting plant. 5.
