Hydro Flow S38

Limescale build-up in heating systems can cause blockages, necessitating the replacement of equipment, decreasing heating efficiency and thereby increasing costs. Just 0.8 mm of limescale can decrease heating efficiency by as much as 10%.

The HydroFLOW s38 is the solution for hard limescale deposits in your small business premises. More powerful than the domestic version, the hs38, the Hydroflow s38 is designed to protect commercial heating systems, as well as appliances such as dishwashers, washing machines to make limescale-stained taps, sinks and surfaces easier to clean.

Unlike a water softener, the Hydroflow s38 does not chemically alter the water or remove minerals. Instead, it applies an electric field so that scale forms in suspension in the water, rather than as a hard encrustation on heating elements and pipe surfaces.
