Highly corrosive and aggressive contamination from Chemical Processing are treated in different ways with a variety of technologies depending on their process confitions and required output. CR Clean Air Group has 60+ years of experience practically all chemical contamination, with some being more regularly seen than others, none that surprise us or where don't have some sort of experience and track record. Our very extensive install base serves well as a true performance guarantee - not just relying on theoretical calculations. Sometimes removal rates in excess of "6 nines" (i.e. 99.9999 %) can be achieved.
