SEA WATER COIL
At KRN Heat Exchanger & Refrigeration Ltd., our Sea Water Coils are engineered to withstand the most demanding marine and coastal environments. Designed to operate with seawater as the cooling medium, these coils ensure efficient heat transfer, durability, and long service life in highly corrosive conditions.
Ideal for marine HVAC systems, offshore platforms, coastal industries, and shipboard cooling applications, KRN Sea Water Coils provide reliable temperature management while reducing maintenance requirements and ensuring compliance with international marine standards.
Design & Construction
