Alfa Laval Finned tube air heat exchangers

The hot medium (e.g. hot water or lube oil) flows through the heat exchanger within the large number of externally finned tubes. One or more fans force air across the tubes and the heat from the hot medium is transferred to the air. To maximize heat transfer, the tubes are equipped with fins that increase the area in contact with the air.
