Nelsen 150K WS2 Mtr Min Tnk
Ensure continuous, high-capacity water softening with the Nelsen 150K WS2 — protect your equipment and cut operating costs effortlessly.

The challenge
Hard water scale buildup drastically reduces the efficiency of boilers, heat exchangers, and water heaters, leading to increased energy consumption and costly equipment repairs or replacements.
For facilities like hotels, laundromats, and manufacturing plants, untreated hard water can shorten equipment lifespan by up to 50% and spike detergent and maintenance expenses, directly impacting your bottom line.
How it works — the technology
The Nelsen 150K WS2 employs advanced ion-exchange resin technology to effectively remove hardness minerals such as calcium and magnesium at a commercial scale.
As hard water passes through the resin media, ions causing scale are exchanged for sodium ions, delivering softened water continuously without interruption to support your facility's high demand.
Capacity & what it handles
- hardness minerals causing scale buildup
- minerals that reduce heat exchanger efficiency
- calcium and magnesium ions
- scale deposits that increase energy usage
- contaminants that shorten equipment life
- water hardness that raises detergent consumption
