Elfin Finned Tubes
In many heat exchanger applications it is necessary to extend the surface of the tube to create an enhanced heat transfer capability. Some methods of manufacture, such as vacuum brazing, do not support the use of dissimilar materials and other methods such as bullet expansion are not always suitable for certain metals (such as titanium due to their elastic cold forming properties) or tube types (such as internally finned tubes). It is also sometimes unacceptable to change the specification of the base tube through deformation (increasing its size to create the mechanical bond with the fins). Wire wound fins have limitations of material choice and the contact characteristics of glued fins can impair heat transfer capabilities. Elfin is a Patented extended surface tube technology which utilises a cold manufacturing process to mechanically bond the fins to the tubes with great precision, effectively overcoming all of these drawbacks. This process imparts certain unique advantages over conventional construction methods, enabling the heat exchanger design engineer to “think outside the box” and gain a significant competitive advantage. One of the main attributes of ‘Elfin’ is the virtually limitless choice of tube and fin materials that can be combined including copper-alloys, aluminium, stainless steel, titanium etc. There is no other product on the market today that can match the unique attributes and exceptional versatility of Elfin at such an affordable cost. With successes in the marine, power generation, rail, compressor and chemical processing industries, 'Elfin' has gained an enviable reputation for quality and flexibility. Return to Finned Products.
