With the Puron® DX plug-and-play indoor air filter against coolant emissions at MWS
MWS is a light metal processing company specializing in aluminium casting and CNC machining that manufactures complex, ready-to-install products with the highest precision. The success story of MWS Aluguss GmbH began in 2004 with the takeover of the renowned Bühlguss foundry in Kufstein and Klagenfurt. In the course of its business success, the company expanded in 2005 and installed a competence center for mechanical processing in Ternberg and a permanent mold casting plant in Slovakia in 2007.
The main customers for MWS products include major customers in the automotive industry, for whom the company has recently been increasingly producing pioneering drive components for electromobility.
In Ternberg, MWS concentrates on machining the cast parts produced by the parent company. The spectrum ranges from engine blocks to various drive types
MWS already uses so-called top-mounted filter devices for the machining centers. These separators are installed directly on the individual machining machines. However, the machining process also produces emissions that cannot be captured directly on the machines. Residual emissions from the coolant mist filters remain in the hall, as the machine emissions cannot be completely separated. This applies in particular to fine aerosols and vaporous emissions.
MWS was therefore looking for a plug & play solution that would achieve a significant improvement in air quality without the need for conversion work. This improvement was to be verifiably ensured by means of several measuring points.
Based on the solution concept presented by Kappa, MWS decided to install eight Puron® DX units. The high-performance hall air purifiers and emission separators were installed on the hall ceiling and ensure permanent and high-grade purification of the hall air.
The pollution caused by fugitive emissions due to residual emissions from the machine extraction systems, which are operated in recirculation mode, and the remaining emission sources was greatly reduced with the help of the devices. This is also confirmed by the results of the measurements carried out: two aerosol/fine dust particle measurements were taken at numerous points in the hall before and after the Puron® DX hall air filters were installed.
The results show that the emission load has been greatly reduced and is approaching the level of outdoor air pollution.
A comparison of the emission load with cigarette smoking makes the improvement clear: the load is reduced by the equivalent of 5 cigarettes smoked per employee per day.
