ENERGY MINIMIZING CONCEPT THE BENCHMARK FOR LOWEST LIFE CYCLE COSTS

: The Original Is And Remains The Standard The Success Story In the last ten years, Scheuch’s EMC filter technology has revolutionized the dedusting process in the cement industry. The technology was able to set new standards with respect to bag length, pressure loss, cleaning pressure and the service life of filter bags. The result has manifested itself in a significant reduction of life cycle costs (LCC). The patented EMC concept is absolutely unique and is considered to be the Best Available Technology (BAT) for process filters – also when compared to electrostatic and reverse-air filters....

The Patented IMPULS Cleaning System Proven a thousand times over in actual use, bags and ensures “uniform aging” of all filter EMC filter technology is based on the patented bags as a result of the positive impact on the IMPULS cleaning system with behavior of the filter differential its specially shaped double-jet This nozzle operates not only with a low overpres- sure on the filter bag, but also with a low required volume of duce an efficient overall system that also assures the cleaning of 10-meter long filter bags. The strong reduction in noise emissions is another positive effect. In com-...
