Refrigeration Air Drying Process

Altec AIR Refrigerated Air Dryers use refrigeration cooling to condense moisture and remove it from a compressed air system.

  • Warm saturated air enters a pre-cooler/re-heater heat exchanger at the dryer inlet and is pre-cooled by outgoing cold air.
  • The pre-cooled air then enters the air to refrigerant heat exchanger and is cooled to its lowest point.
  • As the air is cooled, the moisture it contains changes from a vapor to a liquid and is removed by a stainless-steel mesh separator and discharged from the dryer through an automatic drain valve.
  • The cold air is then re-heated by incoming warm air as it passes back through the pre-cooler/re-heater.
  • The resulting warm air that exits the dryer is clean, dry and ready for use by a compressed air system.

This tool will help you size the perfect RAD Series Non-Cycling Refrigerated Air Dryer for your Compressor Output and Environmental Conditions.
