Application

Alphi-11 Antifreeze 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 draining off 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.
