​Nelsen Commercial Water Softeners with Fleck Controls – Whether your project is a low or high-rise office building, shopping mall, hospital, hotel, college lab, restaurant, casino… Nelsen can assist you with job specifications, submittals, sales and engineering drawings, sizing, and equipment selection. Nelsen Fleck Commercial water softeners are designed for commercial applications ranging from 168,000 to 1,950,000 grains of hardness removal capacity at flow rates up to 250 gpm per tank. We manufacture pre-engineered single and multiple tank systems with full documentation and O&M manuals.

Many water supplies, municipal and groundwater, con­­tain hardness minerals (calcium and magnesium), iron, rust, and sediment. Hardness forms scale on pipes, boilers, heat exchangers, and cooling towers, reducing the heat transfer capabilities of a system as well as in­creasing the cost of operating the system. Nelsen Commercial water conditioners are designed to elim­i­nate unwanted contaminants and to increase process efficiency, saving money now and in the years ahead.
