This water softener system features progressive flow demand operation allowing multiple units to be on or off line dependent on rate of service flow demand. It utilizes direct brine feed from an exterior bulk salt unit to eliminate the extra cost and space of interior brine tanks and manual salt fill. Unit construction utilizes side mount multi-port valves with 3” inlet/outlet piping. This water softener system is designed to eliminate issues of movement through the building and placement at the installation area. Working closely with the customer we tailored the equipment by side mounting control valves and shortened the overall tank height. Each vessel is 42” diameter with 30 cubic feet of resin.
