>Operating Principles

  • Warm, saturated compressed air enters an air to air heat exchanger where it is cooled by cold, dry compressed air passing by in the opposite direction.
  • The temperature of this partially cooled air is finally reduced to the required pressure dew point on entering the refrigerant/air heat exchanger.
  • The resulting condensate is seperated by a service-free water seperator, and expelled with no loss of compressed air via an electronic condensate drain.
