Conventional condensate separators rely on the physical separation/gravitation of the oil from the water so that the oil can be drained separately and the remaining water cleaned through an activated carbon media.

This process is adversely affected in cases where vibration or shocks are present and by any turbulence created by increase in compressed air flow. Furthermore the oil needs to be drained from the system into a container before disposal. Finally over time the water that sits in the primary stage tank becomes stagnant and therefore may present health risks.

Atmospheric air contains already in its origin impurities like: dust, various forms of hydrocarbons and water in form of humidity, which once sucked by the compressor is compressed and delivered to the line together with eventual oily particles.

These polluting agents, interacting among each other, may generate abrasive and corrosive emulsions able to damage the distribution lines, the pneumatic devices and the product itself.

Compressed air is cooled at 30c and condensed water vapour is separated, while 2.8 gr of water for every nm2 of air that condense can remain in the air (compressed at 10 bar as an 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 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 specific pressure.

Over time this may lead to:

- serious damage to the distribution network, the machines using the compressed air and the final product.

- plugs of ice forming in the tubing in certain situations.
