            Maintenance Procedure


            for Heat Exchangers




            Since 1961 Maus Italia’s core business has been developing new
            tools and technologies to facilitate maintenance and production
            of shell and tube heat exchangers. In particular, it has developed
            a complete series of tube bundle pullers and lifters, which fall into
            two categories: aerial and self-propelled, available for on-shore
            and off-shore operations in dangerous area.

                             activities are maintenance. In
                             the past a repair / maintain
                             principle was applied, meaning
            Wwork was only carried out when
            equipment stopped functioning. Such a principle
            increases the risk for equipment and people on a daily
            basis.
            The capacity of heat exchangers - and specifically shell
            and tube heat exchangers - to efficiently perform their
            function has a direct impact on the overall efficiency of
            power plants.
            Fouling is an inherent problem that results in reductions
            in heat transfer and an increase in production costs.
            This requires an ongoing and annual heat exchanger
