Features & Information

Upgraded performance, inclusion of the industry renowned Fleck valve, high capacities and a backup resin tank to eliminate downtime during regeneration sets the SPECTRUM PWS Duplex apart in industrial softening applications.


What is water softening, and why is it necessary?

Water softening is the process of removing minerals like calcium and magnesium from hard water. It’s necessary because hard water can cause limescale buildup in pipes and appliances, reduce soap’s effectiveness, and lead to other issues like dry skin and dull hair.

Is softened water safe to drink?

Softened water is safe to drink, but it may have a slightly elevated sodium or potassium content due to the ion exchange process. If you’re on a sodium-restricted diet, please take this into consideration.

What is the significance of the Fleck valve in these softeners?

The Fleck valve is renowned for its reliability and efficiency in water treatment applications. It plays a crucial role in controlling the regeneration process, ensuring efficient operation and minimal maintenance.

What is the capacity of the PWS range of duplex softeners?

These duplex softeners can handle high capacities, with the ability to soften water up to 12.5 million milligrams (mg) of total hardness between regeneration cycles. This makes them suitable for even the most demanding soft water requirements.
