Water circuits
Heavy 2 stroke engines - Specific features and fields of application

Cooling is necessarily provided by 3 circuits: seawater, low-temperature freshwater and high-temperature freshwater.

• The seawater circuit provides all engine cooling indirectly, using a range of fluids that are easier to operate. To minimize the maintenance requirements associated with seawater, the circuits are very short and require a minimum of equipment. A typical circuit consists of a seawater intake and shut-off valve, a seawater pump, a centralized seawater/freshwater...
