A fin fan cooler is an air-cooled heat exchanger that dissipates heat from process fluids using fans and finned tubes. The fins increase surface area, enhancing heat transfer efficiency through forced air flow. Commonly used in refineries, petrochemical plants, and power stations, it provides effective cooling without water usage. https://www.heatexchanger.co.in/Heat-Exchanger/Fin-Fan-Cooler/
