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. Simply enter the data & conditions and you'll be presented with the Part Number for the RAD Series Air Dryer that will work optimally for those conditions. We will also provide Part Numbers for the Filter Kits that were created to match that RAD Series Air Dryer perfectly.
