Nelsen 120,000 Grain Twin-Tank Commercial (NWS20) Water Softener

For applications that can never run out of soft water, the Nelsen Water Solutions NWS20 120K Twin Alternating System delivers true around-the-clock capacity. Two complete 120,000-grain NWS20 systems work in tandem so that while one tank is in service, the other stays in reserve or regenerates, then the Nelsen 2" MAV (Motorized Alternating Valve) seamlessly switches duty between them. The result is uninterrupted softened water with no downtime during regeneration, a critical advantage over single-tank designs that briefly bypass hard water while they recharge.

A 2" stainless steel electronic meter precisely measures flow and directs regeneration based on real demand, while the lead-free brass 2" valves handle the higher flow rates expected in commercial and high-volume residential settings. The package also includes a 24x41 commercial brine tank fitted with a Nelsen 484 commercial safety valve, air check, overflow elbow, and a 5" brine well with cap, so the salt-storage side of the system arrives complete and ready to plumb.

Twin-alternating designs are the gold standard wherever soft water must be available even during peak overnight or production hours, such as laundries, food service operations, salons, and multi-unit dwellings. Because one tank is always online, the system also keeps each unit's resin freshly regenerated rather than letting it sit exhausted between cycles. Removing hardness before it reaches the building protects boilers, heat exchangers, water heaters, and every fixture downstream from costly scale. With commercial-grade Nelsen and Nelsen components throughout, this NWS20 120K system from Water Softener Plus is built for dependable, continuous hardness control in demanding environments.

Plan for adequate floor space, drain access, and electrical for the meter and MAV when installing this twin system, and confirm your hardness figure so each tank's regeneration is programmed for peak efficiency. Set up correctly, the NWS20 120K Twin Alt runs hands-free, automatically alternating and regenerating to keep your operation in soft water every hour of the day. Built from proven commercial parts, it is a dependable choice for any operation that simply cannot afford to be without soft water.
