Finned Tube Heat Exchanger are used to enhance the heat transfer area to compensate for the low heat transfer coefficient of the fluid in whose contact the extended surface area is provided. This is done to increase the overall heat transfer coefficient since it is determined by the controlling side fluid film co-efficient.

Finned tubes are of two types :

  • Integral finned tubes and externally wrapped finned tubes.
    • Integral low finned tubes are formed by extruding the metal surface thereby increasing the surface area in contact with the fluid on fin side. The diameter over the fin is lower than the tube OD at the ends. Such low finned tubes in copper/CS/SS material of construction are used in shell and tube type heat exchangers for vapor condensing/oil cooling applications.
    • Externally finned tubes are generally used in heating/cooling of atmospheric/compressed air/gas in exchange for cooling/heating of the fluid on the other side. The method of attachment of fin to tube is tension winding /G-groove/L-footed depending upon the criticality of application/temperature to be dealt with by the finned surface. Generally the material of construction of externally finned surface is aluminum and in some cases it is copper too.


Ammus Engineers (Formerly Airfrige) has the capability to design and manufacture all these types of finned tube heat exchangers for various applications as are described herein above
