CLACK industrial duplex parallel water softener, 2 × 25 L resin
This industrial water softening unit is designed for industry, tertiary sector and collective housing. It is based on two columns in parallel to absorb very high peak flow rates and on 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 parallel configuration
Two columns in parallel to absorb very high peak flow rates: both columns work together during peak hours, with sequenced regeneration. 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 rate and daily consumption volume. Appropriately sized resin volume guarantees stable soft water without overly frequent regenerations; a correctly sized salt tank spaces out refilling intervals. In duplex or TWIN configuration, continuous availability is assured, which is essential in process, collective or catering applications where any interruption in soft water supply 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 durable 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 unit'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 rate, plan for appropriate refilling and periodic resin cleaner. DIMM supplies salt, hoses, fittings, bypass kits and maintenance parts compatible with associated products.
Assembled and distributed by DIMM, specialist in water treatment for professionals in Belgium and France: sizing, commissioning, spare parts availability and support throughout the installation's lifespan.
