Watts Meter Demand Duplex Alternating Water Softeners for Hardness Reduction 7100043

The Watts Meter Demand Duplex Alternating Water Softeners are designed for commercial applications, featuring a 2-inch connection size and capable of handling flow rates up to 105 gallons per minute (397 liters per minute). These systems provide hardness removal capacities ranging from 90,000 to 600,000 grains per tank. The PWS20-2 model ensures continuous softened water supply through its duplex alternating design, making it suitable for applications requiring uninterrupted service. Regeneration is initiated by meter demand, and all cycles are fully automatic, eliminating the need for manual operation. The systems utilize a cation exchange process to replace scale-forming calcium and magnesium ions with non-scale-forming sodium ions, effectively producing soft water for various uses, including steam boiler makeup, water heater pretreatment, and cooling tower makeup. Key features include a durable brass-bodied control valve, sophisticated digital electronic controls that store operating history, fully adjustable regeneration cycles, and a high-capacity resin certified by WQA. The tanks are constructed from highly corrosion-resistant materials, ensuring longevity and reliability in operation. The systems require specific installation conditions, including a local drain for wastewater and adherence to specified water pressure and temperature ranges.
