Since ships are isolated vehicles navigating for long periods on their own resources, their self-sufficiency and efficient operation of all systems are vital. Some of the areas in which we operate in the maritime field with our plate heat exchangers and complementary products are as follows.
Cooling Systems on Ships
Engine cooling systems are divided into two. Direct (direct) and indirect, two-circuit (indirect) cooling. Direct cooling is trouble-free and suitable for engines designed from the ground up as marine engines. Cylinder blocks and other equipment with circulating water are protected with seawater resistant alloys and anodes. All outboards and most small powerful inboards are built this way.
A seawater pump driven by the engine absorbs the water, circulates it inside the engine and provides cooling. Since this pump is adjusted to provide sufficient cooling even in the most difficult conditions of the engine, in normal use the engine does not reach the required ideal operating temperature and runs cold. For this reason, this type of ship engine has a by-pass line and additional equipment that regulates the flow of water sent to the engine with a thermostat and ensures sufficient heating of the engine.
In two-circuit cooling systems, fresh water circulates inside the engine, as in land vehicles or stationary industrial engines. Thus, the inner part of the engine is protected from the effects of sea water. Driven by the engine, a seawater pump (which can also water the exhaust system and shell bearings) sends seawater to an MIT Plate Heat Exchanger. As the warmed fresh water coming from the engine circulates through the plates inside the MIT Plate Heat Exchanger, it cools down by transferring its heat to the sea water and returns to the engine.
Central Cooling Systems
In central cooling systems, the fresh water circulation line on the secondary side is cooled by using sea water. The cold water in this chilled fresh water circulation line acts as a refrigerant for the heat exchangers in systems that require cooling such as engine water cooling, jacket water cooling. The use of fresh water in the second circuit reduces the corrosion and wear of the circuit elements in the machine lines, as well as minimizing the backup and maintenance costs.
With MIT Plate Heat Exchangers, which offer the most suitable solutions for all capacities, initial investment costs are kept at minimum levels. Plates such as stainless steel and titanium are offered as standard in our heat exchangers, which can work in full harmony with all systems with different plate angles and types, and different plate materials can be used according to your needs. Standard hulls can be used in the maritime industry, as well as light hulls made of aluminum and aluminum alloy, specially designed for the industry, in cases where weight is important.
Corrosion Resistant Heat Exchangers
The most important problem of the maritime industry is the extremely corrosive effect of sea water. MIT Plate Heat Exchangers offer a definitive solution to this problem with their corrosion resistant complete titanium and titanium alloy 316 plates. MIT Plate Heat Exchangers are the only solution point of the sector with plate, gasket and body types suitable for every process that may be needed on a ship.
