Nelsen 18" x 65" Filter Unit

The Nelsen 18" x 65" Filter Unit from Water Softener Plus delivers substantial commercial filtration capacity, anchored by the proven Nelsen WS1.5EE 1-1/2" control valve. With its larger 18" tank, this system is built for commercial and industrial applications that demand greater media volume and the extended contact time that comes with it, supporting both higher flow and longer service runs between regenerations.

Intelligent, Adjustable Control

The Nelsen WS1.5EE valve combines high-flow capability with sophisticated, easy-to-use control. It supports a 60 gpm service flow rate and 50 gpm backwash, managed by a solid-state microprocessor with accessible front-panel settings. Six fully adjustable cycles provide controlled backwash, down-flow brining and slow rinse, a second backwash, fast rinse, refill, and down-flow service, and an optional double backwash feature can be enabled for optimum regeneration and cleaning efficiency when the application calls for it.

Operators stay informed through a front-panel display showing time of day, days until next regeneration, volume remaining, current flow rate, and total volume used via the built-in totalizer. This comprehensive readout makes it simple to monitor the system at a glance and schedule maintenance proactively. Regeneration can be set as meter immediate, meter delayed, or time-clock delayed, with post-treated water used for the regenerant refill to keep regenerations clean and effective.
