Nelsen 900K WS2H TA Min Tnk

For the largest commercial and industrial water-treatment needs, the Nelsen 900K WS2H-TA twin-alternating softener provides enormous capacity with truly continuous output. Its two pressure vessels alternate duty automatically, keeping one tank in service producing soft water while the other regenerates, so the supply never pauses.

Engineered for heavy industrial demand

At 900,000 grains of total capacity, this system is built for major manufacturing plants, large institutional campuses, high-volume laundries, and demanding process applications. Untreated hard water at this scale rapidly scales boilers, cooling towers, and process equipment, so continuous softening is essential to protecting capital assets and controlling operating costs.

• Twin-alternating configuration for nonstop, high-volume soft water
• Two composite pressure vessels resistant to corrosion
• One 2" Motorized Alternating Valve (MAV) for seamless tank rotation
• One 2" meter enabling demand-driven, resource-saving regeneration
• Large commercial 50" x 60" brine tank with a 484 safety valve
• Designed for continuous heavy-duty industrial operation

The MAV handles vessel changeover automatically, while the 2" meter ensures regeneration is triggered by actual consumption, an efficiency that produces meaningful salt and water savings at this volume. The substantial 50" x 60" commercial brine tank carries a large salt reserve and is protected by a 484 safety valve to guard against overfilling. Because the system is delivered as a coordinated twin-tank package, the components are matched to operate together reliably. For high-demand facilities that cannot afford soft-water downtime and want the operating economy of metered, twin-alternating treatment, the Nelsen 900K WS2H-TA is a powerful, professionally specified solution built to perform under continuous load.

At its core, the system uses ion exchange, with resin exchanging hardness for sodium and brine regeneration restoring the bed, while the twin-alternating arrangement keeps soft water flowing without interruption even during regeneration. At 900,000 grains, this is industrial-scale treatment, and the generous 50" x 60" brine tank provides ample salt capacity to support long intervals between refills, with its 484 safety valve guarding against overflow. For major plants and large campuses, continuous high-volume softening is not a convenience but a necessity: the scale that hard water deposits on boilers, cooling towers, and process equipment at this throughput would otherwise impose steep energy penalties, frequent maintenance, and shortened equipment life, all of which this system is engineered to prevent.
