A Marine Heat Exchanger is used on ships to cool engine and machinery fluids using seawater as the cooling medium. Typically designed as a shell-and-tube exchanger, seawater flows through the tubes while engine coolant or oil circulates around them. It is built with corrosion-resistant materials to withstand harsh marine environments. https://www.heatexchanger.co.in/Heat-Exchanger/Marine-Heat-Exchanger/
