Function of the air dryer
The compressed air produced by a compressor contains a certain amount of relative humidity, which may become condensed. A compressor that produces about 20 m³/s at 8 bar and works for 8 hours at 75%, aspirating air at 20°C with 70% relative humidity, will release about 80 litres of water into the line.
In the process of suction, the compressed air undergoes a first cooling in the air-air exchanger via dry and cold air. The second cooling phase takes place inside the evaporator, where the air reaches the predetermined dew point.
All the condensate that is separated during cooling is treated and discharged automatically by a system of level sensors. Accordingly, the compressed air being output is properly dried, and is suitable for most industrial uses.
