The ECO DRAIN 2000 is based on the physical phenomenon of coalescence. Small drops of a liquid (oil), dispersed in another non-miscible liquid (water), tend to join with the bigger drops and to come to the water surface.

The moisture of compressor tanks, of dryers, of coolers or of our SECO SYSTEM 2000, is composed of a water-oil mixture. It is injected by the compressed air into a noise-shock-absorber, integrated in the ECO DRAIN 2000, to exhaust the pressure.

Water and oil fall into the first of two separating chambers. Before starting these are filled of clean water up to cover the active coal filters. This operation is very important to warrant a long life of filters.

The system is based on the principle of communicating vessels with differentiated levels. The liquid level in the first chamber is two cms higher than the one of the second chamber, due to a flow regulator.

The oil comes to the surface, overflows the second chamber and falls into a suitable tank.

The maximum level sensors detect water and switch on the exhaust valves. The water discharged by gravity can flow out by the drainpipe.

The minimum level sensors switch off the exhaust valves when still water covers the filters. Oil never contacts the active coal filters.

The liquid store up rises again and a new cycle starts.
