Product Uses
Fernox Alphi-11 Protector is a combined antifreeze and inhibitor, which gives long term protection against internal corrosion and limescale in commercial heating and chilled water systems. Fernox Alphi-11 Protector 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.

Fernox Protector Alphi-11 contains mono-propylene glycol.

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. Alphi-11 Protector 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.

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 IC-20 before treating with Fernox Alphi-11 Protector as existing debris can damage the installation.
