A Marine Heat Exchanger is designed to cool engine and machinery fluids on ships using seawater as the cooling medium. It typically uses a shell-and-tube design where seawater flows through the tubes while engine coolant or oil flows around them. These heat exchangers are built to resist corrosion and operate efficiently in harsh marine environments. https://www.heatexchanger.co.in/Heat-Exchanger/Marine-Heat-Exchanger/
