Duplex alternating softener Clack WS1 1/4" 2 x 25 L - ref. CLACK-WS1.25-DP-ALT-25

CLACK industrial duplex alternating softener, 2 × 25 L resin

This industrial water softener is designed for industry, tertiary sector and collective housing. It is based on two independent columns operating in alternation for continuous soft water and a Clack WS1 1/4" valve, world reference for regeneration valve, recognised for its robustness and longevity. By removing hardness (limescale), it protects heat exchangers, boilers, cooling towers, laundries and processes against scaling, secures energy efficiency and reduces maintenance costs.

Duplex alternating configuration

Two independent columns operating in alternation for continuous soft water: one column treats whilst the other regenerates: maximum flow and availability. Volumetric control triggers salt regeneration according to actual consumption, to use only the salt and water necessary.

Why soften in professional environments?

Limescale is the silent enemy of installations: a few millimetres of deposit on a heating element or heat exchanger is enough to reduce efficiency and multiply breakdowns. Softened water extends equipment lifespan, stabilises processes, reduces energy and detergent consumption, and limits production downtime. On hot water networks and heating circuits, softening is the first anti-scaling barrier.

Sizing your softener correctly

Correct sizing depends on water hardness (°TH), peak flow and daily volume consumed. Appropriate resin volume guarantees stable soft water without overly frequent regenerations; a correctly sized salt tank spaces refills. In duplex or TWIN configuration, availability is continuous, which is essential in process, collective or catering environments where any soft water interruption is costly. Our technicians help you choose the most suitable model for your installation.

Clack WS technology

Clack valves in the WS series (WS1 to WS2) equip millions of installations worldwide. Robust, precise and simple to maintain, they control regeneration by volume or electronically, with a wide choice of connections. Combined with composite bottles and selected resins, they form a reliable and lasting technical foundation for professional softening.

Installation & maintenance

The unit connects to the main inlet, after the meter, with an isolation bypass for maintenance. Commissioning consists of setting the inlet hardness, treated volume and regeneration cycles. Routine maintenance is limited to filling the salt tank and periodic outlet hardness checks. DIMM handles assembly, commissioning, spare parts availability and technical support throughout the installation's lifespan.

Quality & compliance

High-pressure FRP composite bottles, food-grade ion exchange resin, proven Clack valve, water-contact materials compliant, CE design. Each softener is assembled and tested by DIMM, with warranty and after-sales service network in Belgium and France.

Salt & consumables

The softener operates with regeneration salt in pellet form, to be maintained in the salt tank. Depending on hardness and flow, plan appropriate refilling and periodic resin cleaner. DIMM supplies salt, hoses, fittings, bypass kits and maintenance parts compatible with associated products.
