Very High-Flow Duplex Water Softener with No Interruption

Two tanks for a continuous supply of softened water

There are two main types of professional water softeners: single-tank softeners and Duplex softeners.

Duplex models combine two resin tanks to treat hard water continuously, even during regeneration cycles.

How Does a Duplex Water Softener Work?

Single-tank high-flow softeners work on the same principle as a household model, but with a much larger volume of resin.

On a professional Duplex water softener, when the first resin tank goes into regeneration, the second automatically takes over to continue softening the water.

The main advantage: a supply of softened water with no interruption, especially valuable for professional and industrial installations that run continuously.

Why Use a Duplex Water Softener?

Continuous service and treatment of large volumes

A water softener reduces the effects of limescale and can help limit scale buildup in equipment, the need for cleaning products, and certain efficiency losses caused by deposits.

  • Continuous treatment even during regeneration
  • Suited to high flow rates
  • Suitable for installations running 24/7
  • Fewer interruptions for resin maintenance

Different Duplex Water Softener Models

Duplex systems are available in several capacities and configurations to match the volume of water to be treated.

A high-capacity water softener

The difference between a duplex water softener and a simplex model mainly comes down to the number of resin tanks. This water softener has two, while a simplex model has only one. This affects the unit's performance.

As a result, a duplex water softener has twice the soft water production capacity of a simplex water softener. This is why businesses install Duplex water softeners. They provide a continuous supply of soft water even when one of the resin tanks is being rinsed.

For on-demand soft water production

In a restaurant or a professional setting, soft water is constantly needed. With the ability to produce 43 liters of soft water per hour, the duplex water softener perfectly meets the needs of industrial users.

Likewise, for a large family, the Fleck duplex water softener is recommended. To meet the needs of a bathroom or an adjoining swimming pool, there is nothing better than installing a duplex water softener. This improves your family's comfort and well-being.

Duplex water softener with or without electricity?

The benefits of a non-electric Duplex water softener mainly lie in its low consumption. You will no longer need large amounts of salt and water for regeneration.

You will no longer have to worry about a power source either, because the equipment uses the water supply pressure to operate. As a result, your electricity bill will decrease significantly.

As for a water softener with an electric valve, a simple adjustment lets you program water treatment in your home or business premises. This model is designed for low-pressure water supplies.
