Limescale System Applications with HydroFLOW®

HydroFLOW® provides an effective, chemical-free solution for treating limescale in water systems by altering mineral crystallisation, so calcium forms as crystals in suspension. It helps maintain efficient operation, reduces energy consumption, and extends the lifespan of equipment across a wide range of industries.

The Challenge of Limescale in Water Systems

Limescale (calcium carbonate) is a widespread issue that often occurs in water systems, particularly where hard water is present. It primarily occurs when water is heated, when there is a pressure drop or turbulence.  It accumulates on heating elements, heat exchange surfaces, pipes, valves, and other equipment, causing energy inefficiency, blockages, and increased wear on equipment. Traditional methods of treatment involve chemical softeners or antiscalants, acid descalers, or physical replacement—often costly, time-consuming, or environmentally harmful. 

HydroFLOW® uses a unique electric field to treat the water non-invasively. This changes how minerals behave, encouraging suspended crystallisation and preventing the formation of hard scale on internal surfaces. The result: cleaner systems, reduced maintenance, and improved performance.
