Designed via feedback from actual field users, The Constant Chlor® Plus MC4-50 dry calcium hypochlorite feeding system prepares and automatically delivers a consistently accurate dose of liquid available chlorine for disinfection applications. This feeding system can supply up to 50 pounds of AvCL/day on a sustained basis without the storage and handling issues associated with liquid bleach or chlorine gas. With the ability to stand alone or be integrated with other process and control equipment, this highly customizable feeder uses NSF Standard 60 listed Constant Chlor® Plus dry calcium hypochlorite briquettes and patented spray technology to produce fresh liquid chlorine solution as needed. The reservoir is filled and volume maintained via an electronically controlled spray manifold where it is continually circulated to maintain unparalleled solution consistency.
