The all-vacuum REGAL™ Gas Chlorinator is used to disinfect drinking water, wastewater, industrial process water and more. It uses 100% chlorine, providing a consistent chlorine residual. It doesn’t create bromates, chlorates, and perchlorates like sodium hypochlorite. The all-vacuum system virtually eliminates the problems associated with pressure-type manifold systems. It incorporates the very best materials with the latest technology in design and construction to reduce maintenance and improve operation.
