Nelsen 450K WS2QC Mtr Min Tnk

The Nelsen 450K WS2QC Metered softener is a high-capacity single-tank system that delivers 450,000 grains of dependable softening with the efficiency of demand-based regeneration. Controlled by a Nelsen WS2 2" meter-equipped valve, it recharges only when actual usage warrants, conserving salt and water.

Efficient high-capacity softening

Designed for large hotels, hospitals, schools, and light industrial sites, this softener removes the calcium and magnesium that scale boilers, water heaters, and process equipment. Keeping those surfaces clean protects efficiency and reduces the maintenance burden that hard water imposes over time.

• 450,000-grain softening capacity for high commercial demand
• Nelsen WS2 2" meter-equipped commercial valve, top mount
• Epoxy-coated lead-free brass valve body for corrosion resistance
• Metered regeneration responding to real water usage
• Top-mount valve position for convenient servicing
• Robust commercial build for long-term reliability

The metered Nelsen WS2 valve is the efficiency core of this system, regenerating based on measured consumption rather than a fixed schedule so the unit avoids wasteful cycles, an advantage that scales with capacity and variable demand. Its epoxy-coated lead-free brass body supports potable service and resists corrosion through years of commercial duty. As a single-tank platform, it offers substantial capacity in a more compact footprint than a twin-alternating system, making it a practical choice where continuous-during-regeneration supply is not strictly required. With a configured weight of approximately 1,427 lbs, the Nelsen 450K WS2QC Metered softener installs as a solid, long-lasting fixture. For operators seeking high-capacity, efficient softening backed by trusted Nelsen control, it is a well-matched solution.

Functionally, the unit relies on ion exchange: resin captures calcium and magnesium and releases sodium, with periodic brine regeneration renewing the bed. As a metered single-tank system, it regenerates on demand, and operators commonly time that brief offline period for off-peak hours. Routine maintenance is limited to keeping salt in the brine tank and the tank reasonably clean. The lasting benefit is protection of expensive equipment, since scale-free boilers, water heaters, and process lines run more efficiently and last longer. For a large commercial site that wants high capacity without the footprint of a twin system, this metered softener offers an efficient, dependable, and economical path to consistent scale control.
