Biocide F7 protects against bacterial and fungal growth in residential heating and non-evaporative chilled water systems. Fernox strongly recommends dosing a Fernox Protector, such as Protector F1 or Antifreeze Alphi-11, alongside Biocide F7 to offer full system protection against corrosion and scale, and to maintain energy efficiency levels.
Biocide F7 is also used to clean and prevent the reoccurrence of microbiological fouling producing jelly-like deposits (fungal growths) in feed and expansion cisterns. Gas produced by fermentation within systems will also be eliminated by the addition of Biocide F7.
Prevents the reoccurrence of jelly-like deposits in low temperature heating systems such as underfloor systems and to clean feed and expansions cisterns
Fast, effective action – starts to work within 24 hours
Simple application, add via a radiator, towel rail, filling loop or inline system filter
Compatible with all Fernox Protectors
High performance, dual action biocide – disinfectant and preservation agent provides short term and long term protection
A single 200ml bottle of Biocide F7 treats up to 280m2 of underfloor systems and 150 litres of system volume
One 200ml bottle of Biocide F7 treats up to 150 litres of system volume. Add via the feed and expansion tank or, for sealed systems, add via a radiator, filling loop, or other point of entry such as a towel rail. Fernox strongly recommends also dosing with a Fernox Protector to protect against corrosion in systems treated with biocide.
For heavily fouled systems, you can perform a biocidal clean with Biocide F7 before draining and flushing the system. Then, refill with additional Biocide F7 to ensure long-term preservation of the system. As before, it is highly recommended to use in conjunction with a Fernox Protector, such as Protector F1 or Protector+ Filter Fluid F9.
Fernox Biocide F7 has been granted a Union authorisation to be used as a biocidal product for this application, across the European Union, with authorisation number EU-0031652-0000.
