MARINE
The maritime sector, including commercial vessels, offshore platforms, and naval installations, relies on complex thermal systems. These systems must operate under extreme conditions, with high demands for reliability, corrosion resistance, and compactness for onboard integration. Whether for propulsion, engine cooling, exhaust gas treatment, or auxiliary systems (HVAC, desalination, fuel conditioning), heat exchangers are essential to the performance of modern vessels.

The main challenges in this sector
The main challenges in this sector
Highly corrosive environment (seawater, humidity, salt)
The components are subjected to accelerated corrosion, requiring highly resistant materials.
Limited access & reduced space onboard
Every centimeter counts: systems must be compact, easy to integrate, and accessible for maintenance.
Resistance to vibrations, shocks, and ship movements.
The equipment must withstand significant mechanical stresses during navigation.
Reliable cooling of engines and generators.
Marine engines require constant heat exchange to prevent overheating, even in tropical waters.
Our involvement in the sector
Nexson heat exchangers, fully welded and compact, are perfectly suited for marine environments. Resistant to corrosion, aggressive fluids, and designed for confined spaces, they provide thermal performance, longevity, and ease of maintenance.
Compact, robust thermal solutions for life at sea
Marine-ready heat exchanger technologies
In marine applications, heat exchangers must combine corrosion resistance, compactness, and mechanical reliability. Nexson’s Plate & Shell exchangers, with their fully welded construction, are engineered for harsh offshore and coastal environments. For systems requiring regular access and flexibility, Thermowave gasketed plate exchangers provide an effective alternative, especially when cleaning or inspection is a key consideration.
Performance across critical shipboard systems
These exchangers are widely used for cooling main and auxiliary engines with freshwater or seawater. They are also essential in fuel conditioning systems for heating and stabilizing heavy fuels. In desalination units, they function as condensers or evaporators, and in gas treatment processes like scrubbers or EGR, they support heat recovery and temperature regulation. Their compact format allows easy integration into the limited space of marine installations.
Durable materials for long-term reliability
Depending on exposure to seawater and fluid aggressiveness, Nexson and Thermowave exchangers are offered in marine-grade materials such as 316L stainless steel, Duplex, Super Duplex, or titanium. The welded design of Plate & Shell units ensures long-lasting sealing and minimal maintenance. Thermowave’s gasketed plates, on the other hand, offer ease of maintenance and adaptability where modular servicing is required. Both options provide efficient and reliable operation in demanding marine conditions.
