Fernox Antifreeze Protector Alphi-11 can be used alongside any circulating pump and can be introduced via the feed and expansion tank or injected directly into the system. The non-toxic, environmentally friendly, clear liquid is EDTA, nitrate and phosphate-free and is accredited with KIWA, Belgaqua, BuildCert and DWTA approvals.
The minimum recommended ‘in-use’ concentration of Antifreeze Protector Alphi-11 is 25 per cent, which can ensure a system is protected down to -11°. However, a concentration of 40 per cent can achieve protection levels down to temperatures as far as -22°. For continued protection Fernox recommends protector levels are checked annually.
