Nelsen 900K WS2QC Mtr Min Tnk

The Nelsen 900K WS2QC Metered water softener provides exceptional single-tank capacity for large commercial and industrial facilities, delivering 900,000 grains of softening under efficient, demand-driven control. A Nelsen WS2 2" meter-equipped valve manages the system, regenerating only when actual water usage warrants.

High-volume, demand-based softening

At this capacity, the system serves major manufacturing plants, large institutional campuses, and high-volume process applications. Hard water at scale rapidly deposits scale on boilers, cooling systems, and heat exchangers, so continuous removal of calcium and magnesium is essential to protecting equipment and controlling energy and maintenance costs.

• 900,000-grain softening capacity for very high demand
• Nelsen WS2 2" meter-equipped commercial valve, top mount
• Epoxy-coated lead-free brass valve body for corrosion resistance
• Metered regeneration based on real consumption
• Top-mount valve position for service access
• Rugged commercial construction for continuous operation

Metered control delivers meaningful efficiency at this volume: the system regenerates according to measured usage rather than a timer, conserving large amounts of salt and water across its service life. The Nelsen WS2 2" valve brings proven, precise commercial reliability, and its epoxy-coated lead-free brass body supports potable service while resisting corrosion under heavy duty. As a single-tank platform, it offers very high capacity in a more compact footprint than a twin-alternating system, suiting facilities that do not require uninterrupted supply during regeneration. For large operations that need powerful, efficient softening with straightforward, accessible maintenance, the Nelsen 900K WS2QC Metered softener is a capable, professionally engineered solution built to handle demanding commercial loads.

This softener works by ion exchange, where resin beads trade calcium and magnesium for sodium and a brine wash periodically regenerates the bed. As a high-capacity single-tank metered system, it regenerates when measured usage warrants, and that brief offline cycle is typically scheduled for low-demand hours. Maintenance centers on the brine tank, keeping salt available and the tank clean. At 900,000 grains, the equipment-protection benefit is substantial: scale-free boilers, cooling systems, and heat exchangers hold their efficiency and avoid costly descaling, so the softener returns its value through lower energy and maintenance costs. For large facilities preferring a single-tank footprint, it delivers powerful, efficient softening with manageable upkeep.
