KalGuard limescale preventer in 22 mm size
Sentinel Commercial now offers its KalGuard system for preventing limescale formation as a 22 mm package suitable for most small commercial buildings. It includes a zinc anode unit, water meter and controller that is set to a 22 mm commissioning mode to create a true plug-and-play solution.
KalGuard permanently conditions water by dosing it with a very low level of stable zinc via an electrolytic process. Calcium-carbonate crystals form as aragonite, which does not form a deposit, rather than a deposit-forming calcite (limescale).
The system is recommended by the UK building-services compliance guide to Part L. Independent tests at Cranfield University have shown its ability to reduce limescale significantly.
