Central Cooling Water System
The water cooling can be arranged in several con-
figurations, the most common system choice be-
ing a Central cooling water system.

Advantages of the central cooling system:

• Only one heat exchanger cooled by seawater,
and thus, only one exchanger to be overhauled
• All other heat exchangers are freshwater cooled
and can, therefore, be made of a less expensive
material
• Few noncorrosive pipes to be installed
• Reduced maintenance of coolers and compo-
nents
• Increased heat utilisation.

Disadvantages of the central cooling system:

• Three sets of cooling water pumps (seawater,
central water and jacket water.
• Higher first cost.

An arrangement common for the main engine
and MAN Diesel auxiliary engines is available on
request.
