The Importance of the Right
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.

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
