NWS20 450K Twin Alt System w/3948 BT
The problem
Hard water in your restaurant or commercial kitchen leads to stubborn mineral buildup that clogs pipes, reduces appliance efficiency, and shortens equipment lifespan.
From boilers to dishwashers, scale formation causes higher energy costs and unexpected downtime — directly impacting your operations and customer satisfaction.
How it works — the softening resin that fixes it
The NWS20 Twin Alternating System uses premium softening resin housed within two 450,000-grain tanks that alternate to ensure continuous soft water supply.
A 2" stainless steel electronic meter precisely measures water volume to trigger regeneration only when needed, optimizing salt and water usage while preventing scale-causing hardness ions from entering your plumbing network.
What it handles
Built for restaurant & commercial kitchen
In the high-demand environment of restaurants and commercial kitchens, continuous access to soft water is vital for cleaning, cooking, and equipment longevity.
The NWS20 450K Twin Alternating System is engineered to meet these challenges head-on, providing reliable, high-capacity softening that supports the intensive water usage typical in food service operations. Its twin tanks and automatic valve ensure your kitchen never faces hard water interruptions that could disrupt workflows or damage equipment.
Built on a genuine Nelsen valve — not a disposable clone
This system runs on a Nelsen control valve — the industry-standard brain of the system. Its parts are stocked by water dealers nationwide and stay available for decades, so a worn seal or piston is a quick, low-cost rebuild — never a throwaway. For a restaurant & commercial kitchen where downtime is expensive, that serviceability is the whole point. We never build on unbranded clone heads that strand you when they fail.
Genuine, serviceable, warrantied — a system you keep for 15 years instead of replacing in four.
