A Fin Fan Cooler (or Air Cooled Heat Exchanger) is an industrial cooling device that removes heat from process fluids using ambient air instead of water. It uses finned tubes and fans to increase heat transfer efficiency, making it ideal for refineries, petrochemicals, power plants, and industries where water is scarce. https://www.unitedheatexchangers.com/heat-exchanger/Fin-fan-cooler/
