Nelsen 900K WS2QC-TA Min Tnk

The Nelsen 900K WS2QC-TA is a heavy-duty, twin-alternating commercial softener engineered for facilities with very high water demand that cannot tolerate any break in soft-water supply. Its two pressure vessels alternate automatically, keeping one tank in service producing soft water while the other regenerates in the background.

900,000 grains of continuous capacity

At this capacity, the system is designed for major industrial plants, large institutional campuses, and high-volume process and laundry operations. Hard water at such scale rapidly fouls boilers, cooling towers, and process equipment with scale, making continuous softening essential to protecting expensive assets and controlling energy and maintenance costs.

• 900,000-grain total softening capacity
• Twin-alternating configuration for nonstop, high-volume soft water
• Nelsen WS2 2" meter-equipped valve, top mount
• Epoxy-coated lead-free brass valve body for corrosion resistance
• Automatic vessel rotation managed by the system
• Metered, demand-driven regeneration for resource efficiency

Metered control is critical at this volume: the system regenerates based on measured consumption rather than a clock, producing significant salt and water savings over time. The Nelsen WS2 2" valve delivers proven commercial reliability, and its epoxy-coated lead-free brass body resists corrosion under continuous heavy duty while supporting potable service. The twin-alternating layout guarantees one vessel is always online, so even round-the-clock facilities never experience soft-water gaps. With a configured weight near 5,906 lbs, the Nelsen 900K WS2QC-TA is a major, install-once industrial platform. For the largest operations that require dependable, very high-volume softening with the efficiency of metered twin-tank treatment, it is a powerful, professionally specified solution.

This system softens by ion exchange, where resin beads capture calcium and magnesium and release sodium, with brine regeneration renewing capacity, and the twin-alternating design ensuring continuous output even during regeneration. At the 900,000-grain industrial scale, brine management and reliable salt supply are integral to operation, and metered control maximizes efficiency by basing regeneration on measured demand. For major plants and large institutions, continuous high-volume softening is essential infrastructure: hard water at this throughput would rapidly foul boilers, cooling towers, and process equipment with scale, imposing heavy energy and maintenance penalties. By preventing that scaling around the clock, the softener protects expensive capital assets and helps keep demanding operations running efficiently and predictably.
