NWS20 450K Meter Mineral Tank System

The Nelsen Water Solutions NWS20 450K Meter Mineral Tank System is a high-capacity single-tank softener engineered for the most demanding residential, agricultural, and light commercial water loads. With 450,000 grains of softening capacity and a 2" lead-free brass metered control valve, it removes heavy hardness while regenerating only on measured demand to keep salt and water use efficient even at this large scale.

Built for big demand

The 2-inch metered valve and commercial distributors provide the flow capacity that large properties and small facilities need, eliminating the pressure loss that would plague an undersized system when several outlets draw simultaneously. Inside the tank, high-capacity resin over a gravel underbed performs continuous ion exchange, capturing calcium and magnesium so scale never reaches your plumbing, water heater, or appliances. The result is consistently soft water that protects equipment across the entire property.

• 450,000 grain softening capacity in a single mineral tank
• Nelsen 2" lead-free brass metered control valve
• Demand-initiated regeneration for efficient operation
• Commercial distributors for uniform flow across the bed
• High-capacity resin seated on a gravel underbed
• Approximately 1,335 lbs weight

Order the brine tank separately so salt storage matches the system's substantial regeneration volume and your preferred reserve. For Progressive Flow Systems, add one CL-COM-34-12 communication cord for the system and one CL-NHBP-20 no-hard-water bypass for each valve. At this capacity the metered control is especially valuable, since avoiding unnecessary regenerations on a 450K system saves meaningful amounts of salt and water over the course of a year. The commercial distributors keep flow evenly spread through the deep resin bed, while the gravel underbed supports the resin and resists channeling for reliable long-term softening. As part of the proven Nelsen Water Solutions softener series from Water Softener Plus, the NWS20 450K delivers commercial-grade capacity and metered efficiency for properties facing serious hard-water challenges.

An installation of this size warrants careful attention to floor loading, drainage, brine logistics, and service access, ideally with an experienced installer. Once commissioned and programmed to your water chemistry, the NWS20 450K regenerates automatically on demand, providing a large or heavily used property with dependable, scale-free soft water for years of service. When the hardness load is severe, the NWS20 450K delivers the muscle to handle it.
