Fleck 2850 AiQ 350 L industrial water softener - ref. FL-2850-AIQ-350

Fleck 2850 AIQ industrial water softener — 350 L resin

The Fleck 2850 AIQ industrial water softener (dual-tank configuration (separate bottle and brine tank)) is designed for municipalities, tertiary sector, hospitality, industry and process applications (boiler rooms, cooling towers, laundries, food processing). It removes hardness (calcium and magnesium) responsible for scaling in heat exchangers, boilers, pipework and equipment, to protect installations, reduce energy consumption and secure processes. It is based on quality ion-exchange resin and a Fleck 2850 AIQ valve with AIQ electronic interface featuring intuitive programming and precise cycle control.

Configuration

In dual-tank configuration, the resin bottle and brine tank are separate, allowing flexible integration in the plant room and easy maintenance.

Operation

Hard water passes through the resin bed which captures calcium and magnesium and exchanges them for sodium: water exits softened. When the resin is saturated, the valve initiates brine regeneration (water + salt), counter-current to the softened water on the relevant models, to fully restore exchange capacity whilst optimising salt and water consumption.

Technical specifications

Why soften water in professional settings?

Hard water scales heat exchangers, boilers, cooling towers and production machinery: energy efficiency drops, maintenance shutdowns multiply and equipment lifespan reduces. By removing hardness, the industrial water softener protects production equipment, stabilises processes, reduces energy bills and lowers maintenance and descaling costs.

The Fleck 2850 valve

A world reference in water treatment, the Fleck 2850 valve combines robustness, reliability and complete cycle programming. AIQ electronic interface with intuitive programming and precise cycle control. Corrosion-resistant body, controlled regeneration and availability of spare parts make it a proven solution for continuous service and economical long-term operation.

Installation & sizing

The unit is installed on the main water inlet, after the meter, with isolation bypass for maintenance. Sizing depends on inlet hardness (°TH), peak flow and daily volume to be treated: our technicians help you select the appropriate model and resin volume, as well as options (meter, mixing valve, brine tank, floor support, gravel bed).

Quality & durability

High-pressure composite bottle (PPO / reinforced fibre) resistant to corrosion, valve body in lead-free brass compliant with ROHS and REACH on brass models, selected ion-exchange resin. Counter-current regeneration to softened water on the relevant ranges, for a clean system and reduced maintenance. Design proven for intensive industrial service.

Application areas

This industrial water softener is intended for high-consumption networks: collective hot water production, steam boiler and heating circuit supply, cooling towers, laundries and laundry services, food processing, cosmetics, surface treatment and pre-treatment before reverse osmosis or demineralisation. By protecting heat exchangers and membranes from scaling, it ensures process reliability and reduces operating costs.

Maintenance & service

Routine maintenance is limited to salt replenishment, residual hardness monitoring and periodic valve inspection. The Fleck design, widely deployed, guarantees long-term spare parts availability and responsive after-sales service. DIMM provides technical support, troubleshooting and consumables supply throughout the installation's lifespan, in Belgium and France.

Salt, gravel & consumables

The water softener operates with regeneration salt (pellets) held in the brine tank. A gravel bed (support layer) is provided on large bottles for flow distribution. DIMM supplies salt, gravel, ACS stainless steel hoses, meters, mixing valves, cartridges and maintenance parts compatible with associated products.
