Kamco SystemSafe KS7 Biocide is a non-oxidising biocide formulated to destroy and prevent the re-growth of slime, algae and bacterial contamination within central heating and low temperature hot water (LTHW) systems. Left unchecked, microbial growth and biofilm formation can reduce circulation, block narrow-bore pipework and underfloor circuits, and accelerate corrosion — KS7 tackles the cause directly, restoring and protecting system efficiency.
Because it is non-oxidising, unlike chlorine or bromine-based biocides, KS7 is suitable for use across all multi-metal systems, including systems containing aluminium components, without the corrosive side-effects associated with oxidising alternatives. It is dosed at a low rate and is particularly well suited to underfloor heating and LTHW circuits where biofilm and microbiological growth are common causes of reduced performance.

Good to Know
KS7 is a non-oxidising formula, unlike oxidising biocides such as chlorine or bromine, making it suitable for all multi-metal systems including LTHW and underfloor heating circuits without the corrosion risk associated with oxidising treatments.
Key Features
Prevents and Treats Biological Growth
Actively combats bacteria, algae and other microbiological contaminants already present in the system.
Controls Biofilm Formation
Prevents the build-up of biofilms, the slimy surface layer that impedes heat transfer and provides a breeding ground for further microbial growth.
Improves System Efficiency
Removing biological contamination helps restore circulation and heat transfer efficiency across the system.
Non-Oxidising Formula
Works differently to oxidising biocides like chlorine or bromine, avoiding their associated corrosion risks.
Suitable for All Multi-Metal Systems
Compatible across mixed-metal heating systems, including underfloor heating and LTHW systems.
Low Dosage Rate
Effective at a standard dosage of 500ml per 100-litre system, keeping treatment straightforward to calculate and apply.
Important Safety Information
KS7 is an acidic formulation (pH 3.0–5.0 concentrate) carrying hazard classifications for skin and eye irritation. Wear protective gloves and eye protection when handling, and consult the safety data sheet before use.

Frequently Asked Questions
What is Kamco KS7 Biocide used for?▼
KS7 is used to destroy and prevent the re-growth of slime, algae and bacterial contamination in central heating and LTHW systems, protecting against biofilm build-up that can restrict circulation and heat transfer.
What is the correct dosage rate for KS7?▼
The standard dosage is 500ml per 100 litres of system water content. Refer to the safety data sheet for full dosing and handling guidance.
Is KS7 suitable for aluminium systems?▼
Yes. As a non-oxidising biocide, KS7 is suitable for all multi-metal systems, unlike oxidising biocides such as chlorine or bromine which carry a greater corrosion risk on mixed-metal circuits.
Can KS7 be used in underfloor heating systems?▼
Yes, KS7 is formulated for use in all systems including under-floor heating and LTHW systems, where biofilm formation is a common cause of reduced circulation and efficiency.
What pack sizes are available?▼
Kamco SystemSafe KS7 Biocide is available in 500ml (BSB001) and 10L (BSB003) pack sizes.
