Fernox Antifreeze Protector Alphi-11 is a combined antifreeze and inhibitor, which gives long term protection of domestic central heating systems against internal corrosion and limescale formation. It prevents corrosion of all metals found in these systems, i.e. ferrous metals, copper and copper alloys and aluminium.

Fernox Antifreeze Protector Alphi-11 is compatible with all metals and materials commonly used in central heating systems. For continued protection we recommend Protector levels are checked regularly (annually). The concentration of the product can be easily measured on site using a water test kit or by using a refractometer.
