NWS20 450K Twin Alt System w/3948 BT

The Nelsen Water Solutions NWS20 450K Twin Alternating System with 3948 brine tank is a high-capacity softening powerhouse engineered for the most demanding commercial and industrial water loads. Two 450,000-grain NWS20 systems share duty through a Nelsen 2" Motorized Alternating Valve, guaranteeing a continuous supply of soft water as one tank stays online while the other regenerates or holds in reserve. There is never a moment when the facility receives untreated hard water.

Continuous high-volume softening

A 2" stainless steel electronic meter tracks gallons treated and initiates regeneration on actual demand, an essential efficiency feature at this scale where unnecessary cycles waste significant salt and water. The 2" lead-free brass valves are sized to deliver the high flow rates that large facilities require without creating pressure loss across the system, keeping every point of use supplied even under simultaneous heavy demand.

• Two 450,000 grain NWS20 systems for true uninterrupted service
• Nelsen 2" MAV automating tank-to-tank switching
• 2" stainless steel electronic meter for precise demand control
• 2" lead-free brass high-flow control valves
• 39x48 commercial brine tank with Nelsen 484 safety valve, air check, overflow elbow, and 5" brine well with cap
• Approximately 2,710 lbs total weight

This system is at home in manufacturing plants, large hospitality operations, institutional laundries, and process-water settings where scale control protects expensive boilers, heat exchangers, and production equipment. Hard water that reaches a boiler or heat exchanger forms an insulating scale layer that wastes fuel and can lead to costly failures, so removing it upstream is a sound long-term investment. The oversized 39x48 brine tank supports the frequent, high-volume regenerations such capacity demands and arrives complete with its safety valve, air check, overflow elbow, and brine well. Assembled from trusted Nelsen and Nelsen commercial components, the NWS20 450K Twin Alt from Water Softener Plus is built to perform reliably under continuous heavy use, delivering soft water that safeguards an entire operation.

An installation of this magnitude warrants careful planning for floor loading, drainage, brine handling, and service access, ideally with an experienced commercial installer. Once commissioned and programmed for your water, the NWS20 450K Twin Alt operates automatically, alternating and regenerating on demand to keep a large facility reliably supplied with soft water.
