Constant Chlor® Plus Model MC4-50 Dry Calcium Hypochlorite Feeder

Designed via feedback from actual field users, the feeder is markedly different from erosion feeders currently on the market. The spray process dissolves material from the bottom of the briquette bed for consistent results. The feeder is NSF/ANSI 61 certified to prepare and automatically deliver a consistently accurate dose of liquid available chlorine for drinking water applications.

Our Constant Chlor® Plus Briquettes are designed specifically for use in the Constant Chlor® Feeder, and are NSF 60 certified for use in drinking water.
