Compressed Air Circuit
Humid hot air entering air dryer is cooled in the cooler. At this time, the condensate is separated from the
air by the drain separator and automatically discharged. The dry air is heated by the reheater until it
gets about the same temperature as that of ambient air. It is then discharged from air dryer outlet.
Refrigerant Circuit
The Fluorocarbon charged in the refrigerant circuit is compressed by the compressor and cooled by the
condenser to become liquid. Then, going through the capillary tube, the refrigerant pressure and
temperature (evaporating temperature) decreased rapidly.
Passing through the cooler part, it draws
heat from the hot compressed air and intensely boils. Finally, it is sucked into the compressor again. The
hot gas bypass valve opens to prevent compressor from freezing when compressed air is too cold.
