Refrigerated Air Dryers

Refrigerated Air Dryers

Description

SALIENT FEATURES :

  • CFC Free, Eco-friendly refrigerant
  • Constant dew point at all varying load
  • Two stage effective moisture separation
  • Lower power consumption
  • Built with necessary protectors for electrical & refrigeration systems
  • Most modern refrigerant system components and pressure switches.
  • Automatic, maintenance free and user friendly
  • Compact design, requires less floor space

PRINCIPLE OF OPERATION

Warm compressed air enters the pre cooler (Air/Air Heat Exchanger)where it is precooled by outgoing cold air.Pre-cooling makes it possible makes it possible to use a smaller(More Economical) refrigeration unit.Then the pre-cooled air enters the evaporator(Air to Freon Heat Exchanger) where it is cooled down to +3C.At this cool temperature ,water condenses into liquid droplets,which are removed from the air stream by a very efficient Moisture Separator and automatically discharged to drain by an Automatic Drain Value.

The cold dry compressed air passes back through the secondary side of the pre cooler (Air to Air Heat Exchanger) where it is reheated by the incoming warm air.Reheating the outgoing compresses air increased the volune of the air enabling it to do more work and is also prevents pipe sweating .The air enabling it to do more work and is also prevents pipe sweating.the Co-ex Heat Exchanger has no extended surfaces or Sharpe corners that collect dust,dirt or oil residue.their self cleaning smooth surface tube in tube design will maintain the same heat transfer efficiency throughout the dryer’s life Any dust or dirt will be washed out from the air system along with the condensed moisture at the Moisture Separator.
