Ocean-going vessels, crossing the seven seas and covering distances between five continents, require advanced refrigeration and air conditioning systems for reliable and efficient operation. The extreme and constantly changing conditions on oceanic routes necessitate the use of high-precision and durable technologies that maintain stable pressures and temperatures. Moisture removal, proper maintenance of refrigerants, and leak prevention are key factors ensuring the equipment’s resilience, protecting the mechanical systems from corrosion and wear. These refrigeration and air conditioning systems enhance efficiency while complying with modern environmental standards, meeting the needs of the global shipping industry.
