Nelsen 300K WS2 Mtr Min Tnk
Maximize uptime and protect your equipment with the Nelsen 300K WS2 commercial water softener.

The challenge
Hard water scale buildup leads to costly equipment failures, reduced energy efficiency, and increased maintenance expenses in commercial operations.
Without effective water treatment, boilers, water heaters, and heat exchangers suffer up to 20% efficiency loss and shortened lifespans, driving up operational costs and risking downtime.
How it works — the technology
The Nelsen 300K WS2 uses high-capacity ion-exchange resin media to remove hardness minerals from water at a commercial scale, preventing scale formation.
Its advanced meter-controlled regeneration ensures continuous soft water supply with minimal downtime, optimizing performance and operational efficiency.
Capacity & what it handles
- hard water scale and minerals that cause buildup
- up to 300,000 grains of hardness per regeneration cycle
- scale-related inefficiencies in boilers and heat exchangers
- detergent overuse by up to 30% in laundry operations
- scale damage to dishwashers, ice machines, and steamers
