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.
