The Fernox F7 Biocide provides effective control of bacteria, fungi, and algae in central heating systems. These microorganisms can create slime and biofilm, which restrict water flow and accelerate corrosion. Therefore, regular treatment with Fernox F7 helps maintain clean and efficient systems.
Biological contamination often develops in low-temperature or underfloor heating circuits. As a result, Fernox F7 Biocide plays a key role in protecting modern heating installations.
What Is Fernox F7 Biocide?
Fernox Biocide is a specialist heating system treatment formulated to kill bacteria and algae. It targets biological growth that standard inhibitors do not control.
Unlike general disinfectants, Fernox F7 is designed specifically for closed heating systems. Consequently, it delivers effective microbial control without harming system materials.
How Fernox F7 Biocide Works
Once added to the system, Fernox F7 circulates with the heating water. It breaks down biofilm and prevents microorganisms from multiplying. Therefore, the system remains free from sludge-forming biological growth.
Because the biocide works throughout the circuit, it protects pipework, radiators, pumps, and underfloor heating loops.
Controls Bacteria and Algae
Fernox Biocide eliminates bacteria, fungi, and algae that cause slime and contamination. As a result, it reduces the risk of blockages and efficiency loss.
Prevents Slime and System Blockages
Biological growth can trap debris and restrict circulation. Therefore, Fernox F7 helps keep systems clean and flowing freely.
