All atmospheric air contains some amount of water vapor. Now, think of the atmosphere as a giant, slightly moist sponge. If we squeeze the sponge very hard, the absorbed water will drip out. The same thing happens when air is compressed, which means the concentration of water increases. In order to avoid future problems in the compressed air system, wet air needs to be treated. This is done using after coolers and drying equipment.
How to dry the air?
Atmospheric air contains more water vapor at high temperatures and less water vapor at low temperatures. This has an effect on the concentration of water when the air is compressed. For example, a compressor with an operating pressure of 7 bar and a volume of 200 l/s, compressed air at a relative humidity of 80% and then a temperature of 20 degrees, will release 10 liters of water per hour from the compressed air pipe. Problems and disturbances may occur due to water precipitation in pipes and connecting equipment. To avoid this, the compressed air must be dried.
