Clack 40-115 gpm Systems

Features Clack WS2EE 2″ Control Valves

Nelsen Water Solutions’ point-of-entry water softening systems are engineered to remove hardness efficiently. They are designed for mid-size commercial/industrial applications ranging from 96,000 to 600,000 grains of hardness removal capacity at flow rates up to 115 gpm per tank with the 2″ valve. They can be network configured from 1-6 systems to accommodate demanding, large water volume requirements. We manufacture single and multiple tank systems with full documentation and O&M manuals.
