Fernox Biocide F7 200ml is a high-performance biocide designed to prevent bacterial contamination and fungal growth in underfloor heating, low-temperature heating and chilled systems.
It also helps clean and prevent the recurrence of microbiological fouling, including jelly-like deposits caused by fungal growth in feed and expansion cisterns. Biocide F7 starts working within 24 hours and provides both short-term disinfectant action and longer-term preservation.
One 200ml bottle treats up to 150 litres of system volume or up to 280m² of underfloor heating. Fernox recommends using Biocide F7 alongside a Fernox Protector, such as Protector F1, to provide protection against corrosion and scale.
