Continuous Helical "KL" Form


        The Knurked Footed fin is locked mechanically on the tube by our Finning Machine.


         Advantages and Disadvantages of KL Form Finned Tubes;

  • The connection of knurled footed fin and tube strengthen the mechanical bond.
  • It improves the heat conductivity efficiently.
  • There is no turbulence. For this reason, the noise of air is in low level.
  • Retaining dust and similar things is not available.
  • It is expensive than Crimped, L, LL and G Forms.
