Things You Should Keep In Mind When Looking For Refrigerated Air Dryers
Compressed air can damage applications that require moisture-free air. Atmospheric air entering the air compressor inlet contains water vapor.
In an air compressor, the heat from compression and pressure forces water vapor to condense into liquid droplets. You can also look for the highest quality refrigerated air dryers through the web.

These droplets travel downstream and can damage your product, air equipment, cylinders, and air motor.
The refrigeration dryer absorbs air containing moisture from the exhaust compressor and lowers the temperature by condensing the moisture into the water and separating it from the air before damaging the product and equipment.
Compressed air enters the air dryer at about 100 F. Air enters the air-to-air heat exchanger. In this heat exchanger, the supply air is pre-cooled by the cold exhaust air. The air then enters the heat exchanger with an air cooler which cools the air to about 35 F.
At this lower temperature, the moisture in the air condenses, separates from the air, and is expelled from the device. Finally, the air flows through the aforementioned air-to-air heat exchanger, which means that the incoming warm air can reheat the cooler air as it leaves the air dryer.
The compressed air coming out of the dryer has a dew point at a pressure between 35°F and 50°F.
2 TYPES OF REFRIGERATED DRYERS
- No cycling
- To go cycling
This is done by the type of hot mass that maintains the temperature after the air compressor shuts off the cycle.
