Nelsen 24" x 72" Filter Unit

The Nelsen 24" x 72" Filter Unit from Water Softener Plus is the largest in this commercial filtration lineup, delivering maximum media capacity for the most demanding commercial and industrial water-treatment applications. At its core is the proven Nelsen WS1.5EE 1-1/2" control valve, providing intelligent, fully automated operation for high-volume sites that cannot afford downtime or inconsistent performance.

Maximum Capacity Filtration

The expansive 24" x 72" tank holds a very large media bed, supplying the capacity and extended contact time that big facilities need to treat high volumes effectively while stretching the interval between regenerations. The Nelsen WS1.5EE valve drives the system with a 60 gpm service flow rate and 50 gpm backwash, controlled by a solid-state microprocessor with accessible front-panel settings. Six fully adjustable cycles manage controlled backwash, down-flow brining and slow rinse, a second backwash, fast rinse, refill, and down-flow service, and an optional double backwash feature provides optimum regeneration and cleaning efficiency for challenging water.

Comprehensive monitoring keeps operators firmly in command of this large system. The front-panel display shows time of day, days until next regeneration, volume remaining, current flow rate, and total volume used through the built-in totalizer, while regeneration can be configured as meter immediate, meter delayed, or time-clock delayed to match the facility's demand profile.
