A refrigerated air dryer cools compressed air so water vapour condenses and can be drained away. It is the most common dryer for general industrial air.
The Refrigeration Cycle
- Compressed air passes through an air-to-air heat exchanger.
- Refrigerant cools the air to about +3 °C.
- Condensed water is separated and drained automatically.
Why It Works
- Cold air holds less moisture than warm air.
- Cooling forces the excess moisture to condense.
- The result is dry air at a stable dew point.
Maintenance
- Clean the condenser and check the drain regularly.
- Keep the room ventilated for efficient cooling.
- Service the refrigerant circuit per the schedule.
What dew point does a refrigerated dryer give?
Typically +3 °C pressure dew point, which suits most general industrial applications.
