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.

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:

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.
