There are two types of cooling systems direct and two phase (indirect) cooling. Direct cooling is free of problems, and suitable for engines that are originally designed as sea engines. Cylinder blocks and other equipments having circulating water in it, are protected by compounds and zinc. All external sea engines and small powerful internal engines are made in this way. A sea pump triggered by engine absorbs and circulates the water in the engine so cooling is achieved. This pump is designed in the way of being able to make cooling in such situations that the engine operates hard. SHIP-COOLING-SYSTEMSThat is why in normal usage, the engine never reaches ideal operating temperature and works cold. Because of this, with a by-pass line and a thermostat, there are some appliances are developed to provide enough engine heating and control the flow rate of water sent to the engine. In two stages cooling systems, utility water circulates in the engine (just like in land vehicles and stationary industry engines) so internal parts of the engine are protected from the effect of the sea water. The sea water pump triggered by the engine, transfers sea water to the New Roc Plate Heat Exchanger. The hot utility water coming from the engine, circulates in the plates and gets cold with the help of sea water and turns back to engine.
