Economical Duplex Water Softener, 450 to 1,000 Liters

Water softener overview

This range of professional water softeners can soften up to 10 m3 of water per hour, with resin volumes from 2x225 to 2x500 liters to treat very high hardness levels.

The main advantage of a Duplex model is that when one resin tank needs to regenerate, the other takes over. This keeps your water softener operating 24/7. Your water supply is never interrupted, and your water is always perfectly softened.

Water softener specifications

- Fiberglass-reinforced polyester tank

- Polyethylene brine tank with top lid

- Highly uniform bead-size cation exchange resin for food-grade use

TM73 valve specifications

- Made of noryl - Inlet / outlet diameter : 1"1/2 - Operating pressure : 2 to 6 bars - Operating temperature : 4 to 35°C - Power supply : 230V - 12V / 50Hz - Upflow regeneration - Maximum flow rate : 10 m3/h

Caution : This valve's flow rate is limited to 10 m3/h despite the large resin volume. This range of water softeners is therefore designed for high hardness levels : 300°f (for the 2x500-liter model) at a flow rate of 10 m3/h or 600°f at 5 m3/h.

Cost-saving upflow operation

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

The largest Duplex models operate with 2 valves connected in parallel to optimize flow rate by using both tanks at the same time when neither is regenerating its resin. The 2 valves are connected by a supplied interlock cable to ensure they never regenerate at the same time.
