The VDL Klima box cooler, with its compact design and large cooling capacity, is used on board ships to cool main engines, auxiliary engines and generator sets. The engine's cooling water flows through a highly efficient V-shaped copper alloy tube bundle built into the vessel's box cooler. Raw water flows over the tube bundle via slots at the top and bottom. The heat from the ship's engine can thus be transferred into the open water.
Water circulation is caused by the physical phenomenon of thermal siphoning: hot water rises and cold water falls.
Impressed Current Anti-Fouling system (ICAF)
Although the Klima box cooler requires little maintenance, the constant exposure to seawater will cause a build-up of algae and shellfish. Such biological growth has a negative effect on heat transfer. The highly effective ICAF system can prevent this.
