How does refrigerated air dryer work?
As the name implies, a refrigerated air dryer works by cooling down the air (like a refrigerator). The warm wet air enters the dryer, where it is cooled down to about 3 degrees Celsius. All water vapor that was in the air condenses into water. The liquid water is then removed from the compressed air by a water-trap.
How often should an air compressor be serviced?
How often should you service? Air compressor servicing may be carried out at set intervals (e.g. every 12 months) but is more often based on hours. A 3,000 hour service, therefore, might be carried out anywhere between 6 and 9 month intervals depending on the level of activity during that period.
How often should air compressors be inspected?
The recurrent inspection of compressors is based on the risk assessment for air compressors. As a rule, the inspection takes place every 4 years. The inspection can be carried out by the service technician in connection with maintenance.
How often should I change my air dryer filter?
Maintenance
- For severe service applications, such as residential refuse trucks or school buses, the air dryer cartridge should be replaced every year or 100,000 miles.

What special valve is used in a refrigerated air dryer?
What special device is used with refrigerated air driers? A hot gas bypass valve. It monitors the pressure in the evaporator and allows hot gas to enter the suction line at any time there is no or reduced load on the evaporator.
How does an air dryer work on an air compressor?
A compressed air dryer is a piece of equipment designed to separate water vapor or moisture (de-humidify) from industrial process air. In the typical system, a compressor draws in humid air and compresses it, which raises the air temperature and then cooling the air condensing water vapor out of the unit.
