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