Description:

A keel cooler is a closed circuit cooling system mounted externally on the vessel’s hull below the waterline. The concept of keel cooling is similar to the application of a radiator on a car. Engine coolant is circulated through the keel cooler, which transfers heat from the coolant before it returns to the engine. The keel cooler is in constant contact with seawater allowing the cooling system to efficiently transfer heat between the coolant and seawater
