Sentinel X400 Sludge Remover 300mL

Sentinel X400 sludge remover, 300mL
High performance cleaner for central heating systems. To remove built-up magnetite sludge, to restore circulation to radiators and pipework and to prepare for the installation of new components, major boiler manufacturers recommended that older systems should be cleaned with Sentinel X400 High Performance Cleaner.

1 litre of Sentinel X400 is sufficient to treat a typical domestic system of 8 to 10 radiator panels. Larger systems should be dosed with 2 litres. Sentinel X400 should be circulated, preferably at normal operating temperature, with all valves open and the pump turned to maximum flow for a minimum period of 2 hours or until satisfactory performance is restored.
