    603070 Fernox Detail

    Description Fernox Antifreeze & Protector Combined Alphi-11 5Ltr Renders water non-corrosive to steel cast iron copper brass and aluminium Combined antifreeze and inhibitor Prevents limescale build-up Compatible with all metals and materials commonly used in heating systems Prevents bacterial contamination Product Uses Fernox Protector Alphi-11 is a combined antifreeze and inhibitor which gives long term protection against internal corrosion and limescale in commercial heating and chilled water systems. It is especially recommended for use in solar systems. Fernox Protector Alphi-11 is compatible with all metals and materials commonly used in central heating systems including aluminium. For continued protection we recommend Protector levels are checked regularly (annually). The concentration of the product can be easily measured on site using a Fernox Protector test kit. Physical Properties Fernox Protector Alphi-11 contains mono-propylene glycol. Colour: Colourless Odour: Mild Form: Clear liquid pH (conc) 5.7 – 6.1 pH (soln 25%): 7.0 – 7.5 SG: 1.04 at 20°C Application and Dosage The minimum recommended “in-use” concentration of the product is 25% in order to ensure adequate corrosion protection. This concentration will protect down to -11°C. A concentration of 40% will protect down to -22°C. Protector Alphi-11 can be introduced via the feed and expansion tank or injected directly into the system via a suitable point (e.g. dosing pot). Introduce into the system after having drained a quantity of water at least equal to the amount of Alphi-11 to be added. Engage the circulating pump and have the system online for a few hours in order to achieve an even distribution. Concentration 25% 30% 35% 40% Protection -11°C -15°C -18°C -22°C In single feed indirect cylinders e.g. "Primatic" or similar potable water chemicals must be used. We recommend untreated systems are thoroughly cleansed and flushed using Fernox Restorer IC-20 before treating with Fernox Protector Alphi-11 as existing debris can damage the installation. Packaging Handling and Storage Fernox Protector Alphi-11 is supplied in 5 and 25 litre containers. Fernox Protector Alphi-11 is classified as non-hazardous and non-irritant but as with all chemicals keep out of reach of children. Do not mix with other chemicals with the exception of Fernox products. No not take internally. In case of contact with eyes or skin rinse immediately with plenty of water.
