Sentinel X400 High Performance Cleaner Rapid-Dose 300ml

The Sentinel X400 High Performance Cleaner Rapid-Dose has been created for cleaning central heating systems that are older than six months. It works by removing the build-up of sludge and to eliminate radiator cold spots, restoring even heat distribution. With the Rapid-Dose it makes cleaning the system even quicker as you don’t need to drain or depressurise the system, and it includes an adaptor to fit directly into the radiator or boiler filling loop. The Rapid-Dose adaptor features Sentinel’s visible bullet, which will stop water from escaping the system and shows you when dosing is taking place as the bullet will move down the tube.
