NWS20 600K Meter Mineral Tank System

The Nelsen Water Solutions NWS20 600K Meter Mineral Tank System represents the top of the single-tank metered range, delivering a formidable 600,000 grains of softening capacity for the heaviest residential and light commercial demands. A 2" lead-free brass metered control valve governs the system, measuring actual water usage and regenerating only when the resin bed is depleted to conserve salt and water at scale, where efficiency translates into substantial savings over time.

This complete mineral-tank build includes commercial distributors for even flow, a stabilizing gravel underbed, and a generous charge of high-capacity ion exchange resin. The combination tackles severe hardness loads, exchanging calcium and magnesium for sodium so scale cannot foul plumbing, water heaters, or process equipment. The 2-inch valve ensures the flow capacity that large, high-demand installations require, maintaining strong pressure even when numerous fixtures or processes run at once.

• 600,000 grain capacity in a single mineral tank
• 2" lead-free brass Nelsen metered control valve
• Demand-based regeneration for maximum efficiency
• Commercial distributors and gravel underbed included
• High-capacity softening resin
• Approximately 1,842 lbs weight

Order your brine tank separately to provide the salt storage this capacity demands along with your desired 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. Because the metered valve regenerates only on real demand, a system of this size avoids the considerable waste that a fixed-schedule softener would incur during lighter-use periods. The commercial distributors spread flow uniformly through the substantial resin bed for thorough softening, while the gravel underbed supports the resin and prevents channeling. As part of the Nelsen Water Solutions softener series offered by Water Softener Plus, the NWS20 600K brings commercial-grade hardware and intelligent metered control to homes and facilities battling extreme hard water.

A system this large benefits from professional planning of floor support, drainage, salt handling, and service clearance. Once commissioned and programmed to your hardness and demand, the NWS20 600K regenerates automatically on real usage, delivering reliable, high-volume softening that protects an entire property or facility from the costly effects of extreme hard water. For the toughest hard-water conditions, this flagship single-tank system is built to perform.
