Heat exchangers and coolers are two equipment pieces that play a critical role in enhancing the efficiency of marine vessels by facilitating the exchange of heat between different fluids.

Marine vessels often rely on heat-generating systems like engines, generators, and auxiliary machinery to produce significant amounts of heat during their operation. To ensure their performance, reliability, and fuel efficiency will be optimised, ship owners have to maintain efficient heat management on their marine vessels. And the only way to do this is to invest in the right heat exchangers and coolers.

Here are some ways heat exchangers and coolers help maintain marine vessel efficiency.

Cool the Engines

One way heat exchangers and coolers help maintain the efficiency of marine vessels is to cool the engines. The main propulsion engines of marine vessels release tons of heat during combustion. Once heat exchangers and coolers are installed, they can help regulate the engine temperature by transferring excess heat to seawater or freshwater. In the long run, these components can improve engine efficiency, prevent overheating, and extend engine life.

Recover Exhaust Gas Heat

Heat exchangers can also help optimise marine vessel efficiency by capturing the heat from the exhaust gases. As they capture the heat, they transfer it to a working fluid like water or oil. The recovered heat can be used to preheat combustion air, heat fuel, or generate more power through steam turbines or waste heat recovery systems. Aside from improving marine vessel efficiency, heat exchangers help in reducing fuel consumption as they harness wasted heat.

Cool Fuel Oil

Marine vessels take advantage of various components to ensure they can work optimally. One of these components is fuel oil. For this component to be helpful, it should maintain the right operating temperatures. Heat exchangers and coolers can, fortunately, be utilised to cool and maintain the optimal temperature of the fuel oil before it enters and goes to the engine. These components help reduce the risk of fuel degradation due to temperature discrepancies.

Cool Lubricating Oil

Similar to fuel oil, lubricating oil should also maintain the right temperature before it enters varying parts of a marine vessel. With the integration of heat exchangers and coolers, this type of oil can be cooled to maintain its optimum temperature range. These components work by removing excess heat from the lubrication system, which helps in preventing oil degradation and maintaining the viscosity of the lubricant.

Regulate HVAC Systems

The heating, ventilation, and air conditioning (HVAC) systems of marine vessels should be optimised and regulated to ensure they can work optimally. Heat exchangers and coolers can be added to carry out these functions as they can maintain the temperature and humidity levels inside the vessel, making sure passengers and crew will be comfortable throughout the trip. Heat exchangers work by transferring heat between the circulating air and a cooling medium like chilled water or refrigerant, allowing for effective cooling and dehumidification.

Generate Freshwater

Marine vessels need a reliable supply of fresh water so passengers and crew can use it for drinking, cooking, and sanitation. Heat exchangers can be added and integrated into freshwater generation systems like reverse osmosis or evaporators to desalinate seawater or produce freshwater from other resources. They work by evaporating seawater and condensing the vapour into freshwater, making sure a sustainable source of freshwater exists onboard.
