Areas of Use / Maritime

Ships are isolated vehicles that sail for long periods using their own resources, making self-sufficiency and efficient operation of all systems crucial. We operate in the maritime industry with our plate heat exchangers and complementary products in the following areas:

Cooling Systems on Ships
Engine cooling systems are divided into direct and indirect, two-circuit (indirect) cooling. Direct cooling is smooth and suitable for engines designed specifically as marine engines. Cylinder blocks and other equipment with circulating water are protected with alloys and coatings resistant to seawater. Most outboard marine engines and small but powerful internal combustion engines are built this way. A seawater pump driven by the engine draws water and circulates it within the engine for cooling. This pump is adjusted to provide sufficient cooling even under the most demanding conditions, ensuring the engine operates at the ideal temperature during normal use. For such ship engines, additional devices such as a bypass line and thermostat adjust the flow rate of water sent to the engine, ensuring it reaches the required temperature.

In two-circuit cooling systems, fresh water circulates within the engine, similar to land vehicles or stationary industrial engines, protecting the internal components from the effects of seawater. A seawater pump driven by the engine (which can also supply water to exhaust systems and sleeve bearings) sends seawater to a MIT Plate Heat Exchanger. The heated fresh water from the engine circulates through the plates inside the MIT Plate Heat Exchanger, transferring its heat to the seawater before returning to the engine.

Central Cooling Systems
Central cooling systems use seawater to cool the secondary freshwater circulation line. The cooled freshwater in this circulation line serves as a cooling fluid for systems requiring cooling, such as engine coolant and jacket water cooling systems. Using fresh water in the secondary circuit reduces corrosion and wear on circuit components in machine lines, minimizing backup and maintenance costs. MIT Plate Heat Exchangers offer optimal solutions for all capacities, keeping initial investment costs to a minimum. Our heat exchangers come standard with stainless steel, titanium plates, and other materials tailored to your needs. In the maritime sector, standard bodies can be used, or specially designed lightweight aluminum and aluminum alloy bodies can be used where weight is critical.

Corrosion-Resistant Heat Exchangers
One of the most significant issues in the maritime sector is the highly corrosive nature of seawater. MIT Plate Heat Exchangers provide a definitive solution to this problem with fully corrosion-resistant titanium and titanium alloy 316 plates. MIT Plate Heat Exchangers are the industry’s sole solution with plate, gasket, and body options suitable for any process required on a ship.
