NWS20 210K Twin Alt System w/2450 BT

Continuous soft water at high flow is the promise of the Nelsen Water Solutions NWS20 210K Twin Alternating System with 2450 brine tank. Two 210,000-grain NWS20 units operate as a coordinated pair, governed by a Nelsen 2" Motorized Alternating Valve that automatically transfers service from one tank to the other so treated water never stops, even during regeneration. This eliminates the brief hard-water window that single-tank systems experience while recharging.

A 2" stainless steel electronic meter forms the brains of the operation, tracking gallons used and initiating regeneration only when a tank's resin is exhausted. This demand-based control conserves salt and water while guaranteeing that soft water is always ready, even during the heaviest draw. The 2" lead-free brass control valves support the substantial flow rates required by busy commercial and large residential installations, where undersized equipment would create pressure drop and inconsistent performance throughout the building.

• Two 210,000 grain NWS20 systems for true twin-alternating service
• Nelsen 2" MAV automatically switches between tanks
• 2" stainless steel electronic meter for precise demand sensing
• 2" lead-free brass valves built for high-flow duty
• 24x50 commercial brine tank including Nelsen 484 safety valve, air check, overflow elbow, and 5" brine well with cap
• Roughly 1,350 lbs total weight

This level of capacity suits hotels, car washes, manufacturing rinse processes, and other operations where scale control directly affects equipment longevity and product quality. By removing hardness before it can deposit, the system protects boilers, heat exchangers, water heaters, and plumbing throughout the facility, reducing maintenance and downtime. The generous 24x50 commercial brine tank arrives equipped with its safety valve, air check, overflow elbow, and brine well, so the salt-storage side is ready to connect. Backed by trusted Nelsen and Nelsen components, the NWS20 210K Twin Alt from Water Softener Plus is engineered to deliver dependable, around-the-clock softening for years of demanding service.

When planning the install, allow room for both mineral tanks plus the brine tank and verify electrical service for the meter and motorized valve. After commissioning, the system manages itself, alternating tanks and regenerating on demand so the facility always has soft water on tap, even at the busiest hours of the day or night. With its high capacity and continuous operation, it is well matched to the most demanding commercial water loads.
