Product Data Sheet

Safety Data Sheet

Sentinel X800 Fast Acting Cleaner eliminates magnetite and limescale deposits from heat exchangers, radiators, underflor heating floors and pipework. It restores more uniform distribution of heat in existing installations, for a better heated home and reduced energy bills.

With its unique formulation, combining 3 different chemical technologies, the rapid sludge remover formula penetrates and dissolves corrosion and limescale deposits for rapid and effective removal during cleaning. It acts as a dispersing agent, under neutral pH conditions, eliminating any concerns associated with traditional acidic cleaners. Non-toxic and 100% biodegradable, Sentinel X800 is safe for the environment.

Its formulation also contains agents to ensure the protection of system metals against corrosion during the cleaning as well as preparing the installation for the addition of Sentinel X100 Inhibitor.

Although very effective in manual cleaning, Sentinel X800 reveals its true power and performance in combination with a powerflushing machine such as the Sentinel JetFlush Rapid.

1 litre of Sentinel X800 Fast Acting Cleaner is sufficient to clean a typical system of up to 10 radiators. For larger systems, 2 litres should be used. Where systems are badly fouled, a higher concentration is recommended, i.e. 2 litres for a typical system. This product will not clear a completely blocked pipe.

To clean an older system in accordance with BS 7593 it is recommended that this product is used with powerflushing equipment. In this scenario, administer Sentinel X800 Fast Acting Cleaner via the powerflushing equipment, following the equipment manufacturer's instructions. Alternatively, circulate the product (preferably at normal operating temperature, with all valves open and the pump turned to maximum flow) for a minimum period of 1 hour or until satisfactory performance is restored.

Powerflushing: Follow the instructions supplied with the powerflushing machine.

Open Systems: Dose via F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.

Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.
