The S RANGE is designed specifically to deal with limescale in high pressure steam boilers. The S RANGE enables the use of untreated water for the steam boiler – straight from the mains or the bore hole. Preventing hard scaling on boiler tubes and gradually clearing up existing scale can lead to huge savings due to reduced maintenance costs and improved efficiency. The S RANGE is designed to address the effects of new and existing hard limescale encrustation and is suitable for high pressure steam boilers. Standard units are available up to 120mm in diameter.
