Cooling systems

Heat from diesel engine and auxiliary units is directly or indirectly dissipated to sea water. Exceptions are exhaust gas and radiation.

Temperature control is important

• Wide variation of the cooling energy demand.

• Wide variation of sea water temperature

• Engine sensitivity to temperature deviations

• Preferably independent systems for ME’s (2x) and AE’s for simple adjustment

Water flow can be prevented by air pockets, ice slush or entered material.

Chemical purity is important
