An air cooled heat exchanger uses ambient air to cool process fluids flowing through finned tubes. Fans blow air across the fins, enhancing heat transfer without using water. Widely used in refineries, power plants, and petrochemical plants, it offers efficient cooling, low maintenance, and suitability for dry regions. https://www.heatexchanger.co.in/Heat-Exchanger/Air-Cooled-Heat-Exchanger/
