Oil/water separators of the CSW-.. series are designed for compressed air condensate treatment. The condensate, mainly consisting of water and contaminated with some amounts of not emulsified, floating oil is treated according to the latest technologies. The oil is separated from the water, as a result the condensate can be discharged into the sewage system. Approval of the Deutsches Institut für Bautechnik Berlin, Germany, (DiBt, German approval body for construction products and types of construction) verifies compliance with the legal requirements, e.g. §7a Federal Water Act (Germany).
Oil/water separators of the CSW-.. series consist of a plastic collecting vessel with integrated filter stages and a water outlet as well as of an upstream vent chamber for the condensate inlet. For the CSW-DRUKOSEP series the filter stages comprise a 3-stage combination filter (oil collecting filter, coalescing filter and activated carbon filter) and a downstream safety chamber. For the CSW-DRUKOMAT and CSW-DRUKOMAT PLUS series the filter stages comprise a sedimentation stage with oil outlet (including oil collecting canister with overflow protection) and a downstream prefilter and activated carbon filter.
In addition, the CSW-DRUKOMAT PLUS series is provided with a coalescing filter (preko filter), which considerably increases the service life of the activated carbon and the performance of the oil/water sep-arator. All the separator models are provided with a test valve, a test set, a filter in the vent chamber, and a documentation compartment. The CSW-DRUKOSEP 6-10 and CSW-DRUKOMAT PLUS models have an inspection glass for visually checking the filter (level switch for filter check is available as an option and can be retrofitted).
When mounting the separator in environments where there is a danger of frost, a heating system is optionally available and can be retrofitted at any time (not available for CSW-DRUKOSEP 1-3).
The condensate may enter the oil/water separator either being under pressure or being depressurised. Oil mist occurring upon oil entering is absorbed by means of filters in the vent chamber. In the downstream filter stages the oil is separated from the water and separately discharged from the oil/water separator or collected in the filter and disposed of together with the filter.
All the separator models have a design approval and must therefore not be additionally approved by the responsible authorities.
