PWS15T-L
Watts Pure Water Duplex Twin Alternating Water Softening Systems with Grain Capacities Ranging from 60,000 to 300,000
PWS15T-L Watts Pure Water Duplex Twin Alternating Water Softening System Series delivers continuous, high-efficiency water softening for point-of-use and point-of-entry applications where softened water is required 24/7. These systems utilize a conventional cation exchange process to remove scale-forming calcium and magnesium ions, replacing them with non-scale-forming sodium ions to ensure consistent water quality across a wide range of residential, commercial, and industrial settings.
Each system in the series features the advanced Watts LOCKSMITH™ control valve, a durable, corrosion-resistant brass valve that is highly configurable and easy to maintain. Operated by an electronic controller, the valve stores key operational history for user access and supports metered, demand-initiated regeneration, optimizing salt and water usage while minimizing downtime.
Available in capacities from 60,000 to 300,000 grains, these duplex systems include twin mineral tanks ranging from 12 to 24 inches in diameter, each filled with 2 to 10 cubic feet of high-capacity ion exchange resin. With peak flow rates from 40 to 100 gallons per minute, and standard 1 ½" FNPT inlet/outlet and 1" MNPT drain connections, every model is built for performance and reliability. All components are NSF and ANSI certified, ensuring quality and compliance.
