A commercial use water softener addresses hard water that can build up on industrial equipment, boilers, and other heating and cooling systems by removing the excess minerals in the water and replacing them with salt.
A Professional or Twin Alternating softener unit works by having one tank remove hardness while the other is regenerating. The first tank is full of resin that is saturated in sodium ions. As water is going through the cycle, the resin attracts the calcium and magnesium ions that make the water hard. Up to 480,000 grain capacity.
