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.
