Dessicant Dryers

Compressed air is cooled at 30°C and condensed water vapour is separated, while 2.8 gr of water for every Nm3 of air that condense
can remain in the air (compressed at 10 bar as in the example) in vapour form.

In the event of particularly rapid expansion and/or particular ambient conditions, compressed air for the application may be cooled
to such an extent that the temperature drops below its Dew Point.

If the temperature falls below its dew point (*), further condensation takes place resulting in separation of humidity and formation
of condensate. (*) The Dew Point is the value of the temperature when we have the max. water vapour concentration in the air, at one
specifi c pressure.

Over time, this may lead to:
- serious damage to the distribution network, the machines using the compressed air and the fi nal product.
- plugs of ice forming in the tubing in certain situations.
