Sentinel X400 System Restorer (Sludge Remover)

Sentinel X400 has been formulated for the effective cleaning of existing central heating systems where there is a significant amount of magnetite corrosion debris and sludge.

Sentinel X400 disperses old corrosion deposits and sludge. It is ideal for use where a new boiler or pump is to be fitted to an existing system, or where radiators have cold areas or are partly blocked due to sludge build up.

Sentinel X400 is a non-acid formulation which can be used in all types of indirect heating systems including those containing aluminium components.
