elfin finned tube technology
   Elfin Technology      
Elfin is a patented 'extended-surface tube' design which has been developed by Applied Cooling Technology for today's demanding air-blast heat exchanger applications.

The Elfin range of products, which is available in a wide variety of single-tube and multi-tube configurations, has been designed to offer outstanding levels of performance, durability and flexibility.
Elfin consists of individual fins which are swaged onto the tubes with great precision using the Patented ElfinMaster finning machine, with each fin having a positional accuracy of just a few microns.

The fins, which can be 'collared' or 'collarless' (exposing the primary surface to the airflow), have holes formed to be a precise interference fit with the tube, the resultant mechanical bond negating the need for any further bonding method such as tube-expansion or brazing.

This process imparts a level of flexibility not generally associated with finned heat exchanger tubes.  Almost every aspect of the design can be optimised for the target application and environment.
Elfin is probably the best extended surface technology in the world.
