Level measurement

The challenge:In the production of wind turbines, the exhaust air of oil-sealed vacuumpumps is enriched with a fine, stable oil aerosol. An elimination of these pollutants is essential, as these are harmful to health and the environment.

The challenge:Lubricatingoilsystemsproduceoleagi-noussmokeandoilmist.Aerosolsareahealthhazardandcausedirt,debrisandair/gasmixtures.Aslightnegativepressure in the lubricating oil system and filtering of the oleaginous air are necessary for safe machine operation. Incompactpackages,thespaceforthisimportant filter system is limite

Thickchocolatemassistobecleanedwith a self-cleaning filter system before filling. Previously, this was achieved with an open filtration.

The challenge:Ensuringanuninterruptedcoldchainand creating an overview of the aggre-gatestanklevelsofthecoolingtrailers.

The solution: contec's coalescence filters eliminate up to 99.99% of the sea erosols with alow pressure drop and long service life, sin-ce only solid particles clog the elements slowly. The purified and accumulated oil collected by the filter can be reused and fed back to the pumps.

The solution:

ThecompactseriesoftheCOMSoilmistseparators is the ideal filter system, especiallyinlimitedspaces.TheCOMSensuresanadjustable,continuousvacuum and clean, oil-free air in the lubricatingoiltankoftheturbine. Withaseparationefficiencyof99.98%at0.1µdropletsize,theresidualoilcontent is below 0.1 mg/m

After successful trial with an standard wedge wire filter this was modified for special use. The wedge wire filter CSF700-FDwithflangecoverisveryeasy to maintain and can be integra-tedintotheexistingtracingovertheheatingjacket.Anintegratedmagneticseparator after the filter system provi-des ultimate security.
