Twin Alternating Water Softeners
68-280 gallons per minute
Dual Interlock System 5 Water Softeners are designed and manufactured for high flow rates and uninterrupted service. Both softening tanks will be in parallel service. All brass valves, fiberglass mineral tanks, polyethylene brine tank, and high-quality polystyrene resin are manufactured in the USA dependable operation. Regenerations are initiated when a preset volume of water passes through the water meters. Each control valve is equipped with a water meter and fully-adjustable controls. When a meter zeros out, the system places the exhausted tank into regeneration. An interlock will prevent the second tank from simultaneous regeneration. Electronic timer, as shown above, and hard water bypass are available as options.
