A ruthlessly efficient way to eliminate the build-up of magnetite sludge, X400 is the quick and easy way to eliminate cold spots and restore full heat emission.
"The GASTEC research document is particularly useful to us as we specialise in replacement boilers rather than in new build installations. It helps us to explain to our customers, in black and white, what the problems associated with sludge build-up are and what Sentinel chemicals can do to eliminate these problems and restore optimum efficiency to their heating system. Sentinel products and the back up service they provide are second to none and, as a company, we've always been pleased to work with them but this report helps us promote the fact that we work with a manufacturer which has carried out independent research to prove that its products live up to their claims."
