Doucet Technologies : Combined protection unit (Jet Filter + Centrifugal separator)
.................................................................

The Combined DOUCET Protection Unit includes a DOUCET laminar filter media with slots varying from 100 to 800 microns made of 2 mm thick stainless steel sheet. There are no moving parts. Subsequently, the water flows through a series of DOUCET high efficiency centrifugal separator modules.

The untreated water enters the laminar filter then passes through the filtration media which retains all suspended particles and impurities larger than the slot opening. It then passes through the DOUCET separators where sand, silt and mud settling by centrifugal action are removed in the filtration range of 30 to 50 microns.

The filtered water is of better quality than the effluent of a 50 microns micro-strainer ; it no longer contains any abrasive or clogging particles which are dangerous when present in industrial water for cooling systems, particularly tubular and multicellular exchangers, spray systems, hydraulic joints and automated water circuits.

Since there are no moving parts in the filter and since two complementary, very simple and sturdy techniques are used, our Combined DOUCET Protection Unit (fully automatic) does not require any special maintenance.

Of course, we supply each of the two components separately, i.e. the DOUCET Jet-Filter, or the Standard DOUCET Unit which contains only the high efficiency centrifugal separators.
