Fleck 3150 Commercial Water Softener β 210K to 900K Grain
Protect your equipment and boost efficiency with the Fleck 3150 Commercial Water Softener β scalable soft water solutions up to 900K grains.

The challenge
Hard water scale deposits cause costly damage and efficiency loss in commercial equipment like boilers, water heaters, dishwashers, and chillers. Scale buildup can reduce heat exchanger efficiency by up to 20% in just 18 months and increase energy consumption by nearly 50%, driving up operational costs.
For facilities such as hotels, laundromats, restaurants, and manufacturing plants, untreated hard water leads to premature equipment failure, increased maintenance expenses, and potential downtime β all impacting your bottom line and compliance requirements.
How it works β the technology
The Fleck 3150 Commercial Water Softener removes calcium and magnesium ions responsible for hard water scale through a proven ion-exchange process. As water passes through the resin media, hardness ions are exchanged for sodium ions, effectively softening the water on a large commercial scale.
This continuous treatment protects your water-using equipment and surfaces from scale buildup, ensuring consistently soft water with minimal maintenance and reliable performance suited for high-demand commercial applications.
Capacity & what it handles
- calcium and magnesium hardness ions up to 900,000 grains capacity
- scale buildup that degrades heat exchangers and boilers
- spotting and residue on glassware and dishware
- premature wear and corrosion in plumbing and appliances
- hardness that reduces detergent effectiveness and wastes chemicals
