liquid cooling for reliable performance

Marine transformers regulate voltage for various onboard systems, operating continuously under fluctuating electrical loads. In compact electrical rooms, the thermal load can become considerable. 

Efficient cooling extends transformer life, improves performance, and prevents insulation breakdown due to heat buildup. 

Liquid-cooled transformers are well-suited to marine environments, offering high power density and efficient thermal management in limited spaces. Compared to air-cooled units, they provide quieter operation, improved reliability, and better performance in enclosed or high-temperature compartments. 

Cooling requirements

Transformers generate significant internal heat during continuous operation, especially under fluctuating or high electrical loads. If not effectively cooled, this heat can degrade winding insulation, reduce efficiency, and shorten equipment lifespan. Direct thermal management of the transformer is essential to ensure reliable performance and minimize the risk of overheating or failure.

Closed-loop liquid cooling application:

A dedicated liquid coolant loop absorbs heat from the transformer and transfers it to the vessel’s technical water system via a water-to-water heat exchanger. In isolated locations, dry coolers can serve as a standalone solution.
