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 re-heater 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
drain
from freezing when compressed air is too cold.
