Abstract

In order to optimise the performance of boiler exchangers, avoiding the precipitation of calcium and magnesium carbonates, in addition to the fouling of the circuits caused by residual working products or by other foreign matters existing in the water network, while keeping drinkable the sanitary water produced according to the WRC standards, IABER S.p.A. has developed a treatment with particular fluorurated resins for the exchange surfaces. Such resins adhere to metallic surfaces thus creating a few microns thick coating limiting the adhesion of limestone and of the deposits existing in heating circuits. <IMAGE>
