Helical Serrated Fin
Our serrated fin is a metal strip which has been cut and performed to provide a base flange which is then helically formed under tension around the specified tube. The flange is fused to the tubular base by resistance welding. The fused fin flange and tube contact area exceeds the cross section area of the fin stock assuring a conducting heat path with a higher heat transfer coefficient with strength and durability.
