Nelsen 210K WS2 Mtr Min Tnk
Maximize uptime and protect your equipment with the Nelsen 210K WS2 industrial water softener.

The challenge
Hard water scale buildup in commercial facilities leads to decreased equipment efficiency, increased energy consumption, and costly maintenance downtime.
For example, scale can reduce heat exchanger efficiency by up to 20% within 18 months and increase energy costs by nearly 50%, while also drastically shortening water heater lifespan. These issues translate to higher operating expenses and potential compliance risks.
How it works — the technology
The Nelsen 210K WS2 utilizes advanced ion-exchange resin media to remove hardness-causing minerals such as calcium and magnesium from your water supply at commercial scale.
This process protects your equipment by preventing scale formation, ensuring continuous operation and maintaining optimal efficiency throughout your facility.
Capacity & what it handles
- hardness minerals causing scale buildup
- calcium and magnesium ions
- scale deposits on heat exchangers and boilers
- water spots on glassware and surfaces
- excessive detergent residue in laundries
- potential compliance issues related to water quality
