Duplex alternating water softener Clack WS1 1/4" 2 x 125 L - ref. CLACK-WS1.25-DP-ALT-125

CLACK duplex alternating industrial water softener, 2 × 125 L resin

This industrial water softening unit 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, the worldwide reference for regeneration valves, 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 while the other regenerates: maximum flow and availability. Volumetric control triggers salt regeneration according to actual consumption, using only the salt and water needed.

Why soften water in professional settings?

Limescale is the silent enemy of installations: just 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, water softening is the first anti-scaling barrier.

Sizing your water softener correctly

Correct sizing depends on water hardness (°TH), peak flow and daily consumption volume. Appropriately sized resin volume ensures stable soft water without overly frequent regenerations; a correctly sized salt tank spaces out refilling intervals. In duplex or TWIN configuration, availability is continuous, which is essential in process, collective or catering applications 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 water softening.

Installation & maintenance

The unit connects to the main water 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 refilling the salt tank and periodic checks of outlet hardness. DIMM handles assembly, commissioning, spare parts availability and technical support throughout the system's lifespan.

Quality & compliance

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

Salt & consumables

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