Finned tubular heaters outperform tubular heaters because fins enhance the surface area, allow for faster heat transfer to air, and allow for greater power to be placed in tighter places such as forced air ducts, dryers, ovens, and load bank resistors, resulting in lower element surface temperature. They are comprised of tubular heating elements and have electro-galvanized steel fins. ​

 

Mechanically bonded continuous fins assure excellent heat transfer and helps prevent fin vibration at high air velocities. As the surface area is increased and heat transfer is improved due to fins, it results in lower sheath temperature and maximizing of element life.
