Most cooling systems are made as central cooling systems, meaning that only one or two bigger plate heat exchangers are equipped with titanium plates. Titanium is the only material that can withstand the aggressive seawater without corrosion damages on the plates in the heat exchanger. This means that the central cooler can operate without problems using seawater as the cooling media for the internal freshwater cooling system.

The advantage of a central cooler is that the use of the corrosive seawater is limited to one or two plate heat exchangers, and thereby the use of exotic material for the plate heat exchanger and the seawater pipeline is limited to a minimum, which will reduce the corrosion damage in the cooling system.

The rest of the plate heat exchangers are normally equipped with stainless steel plates. There is no corrosion risk as the heat exchangers work with freshwater
