Marine heat exchangers play an important role of removing the heat produced by a running machinery to ensure smooth functioning of the equipment. It is also necessary to enhance the heat exchanging ability which would reduce after certain amount of time of operation.
The cooling medium used in the heat exchanger depends on the medium used, including other factors.
Along with mediums such as fresh water, air and oil, sea water is also used abundantly in marine heat exchangers as an important cooling source. However, because of the presence of dissolved salts in sea water, corrosion and scale deposits is a common condition in heat exchangers. Maintenance of marine heat exchangers is therefore necessary at regular intervals of time to prevent reduction of heat transfer or failure of equipment
