Economical Duplex Water Softener 40 to 200 Liters
Duplex Water Softeners
Introducing the Duplex Water Softener
This range of commercial duplex water softeners covers all needs from 800 to 3,500 liters of water per hour, with resin volumes from 2x20 to 2x100 liters.
The major advantage of a Duplex model is that when one resin vessel needs to regenerate, the other takes over. This keeps your water softener operational 24/7. Your water supply is never interrupted, and your water is always perfectly softened.

Economical Countercurrent Operation
We chose countercurrent water circulation for these models. This means water flows upward through the resin to be softened instead of flowing downward as in a conventional water softener. This saves 45% on salt and water with each regeneration. A significant saving for a competitive business.
