ChemFree (as our customers refer to us) has been providing chemical free systems for cooling tower treatment and air compressor condensate separation for industrial clients since 1992. In 1994 we began marketing "Safety Sorb" spill control media (which immediately reduces the volatility of hydrocarbon spills and is non-leachable when landfilled) and "EconoPure" string wound polypropylene filters. In 1998 we brought out our "Blue Zapper" (using MicroBan) biocidal filter cartridges for high flow industrial processes where biocidal chemicals cannot be used.
