Production Technique & Applications

‘G’ Fin ( Also Called “Embedded Fin” Or “Edge Grooved Fin”)
The Fin Strip Is Wound Into A Machined Groove And Securely Locked Into Place By Back Filling With Base Tube Material Under Pressure. This Ensures That Maximum Heat Transfer Is Maintained At High Tube Metal Temperatures. Maximum Operating Temperatures For This Fin Type Is 450°C.

‘L’ Fin ( Also Called “Shoulder Tension Fins”, “Wrap On Fins”)Br />The Strip Material Is Subjected To Controlled Deformation Under Tension Giving The Optimum Contact Pressure At The Foot Of The Fin Onto The Base Tube Thus Maximizing The Heat Transfer Properties. The Foot Of The Fin Considerably Enhances The Corrosion Protection Of The Base Tube. Maximum Operating Temperature For This Fin Type Is 150°C.

‘KL’ Fin (also Called Knurled “L” Fin )
Manufactured Exactly As The ‘ L’ Fin Except That The Base Tube Is Knurled Before Application Of The Fin Foot. After Application The Fin Foot Is Knurled Into The Corresponding Knurling On The Base Tube Thereby Enhancing The Bond Between The Fin And Tube Resulting In Improved Heat Transfer Characteristics. Maximum Operating Temperature For This Fin Type Is 260°C.

Extruded Fin ( Bimetallic Fin )
The Main Tube (mother Tube) Is Covered With An Aluminum Muff And The Fins Are Formed Using The Forming Force . This Results Into Very Good Mechanical Bonding Of The Aluminum Muff With The Mother Tube To Have A Very Good Heat Transfer Properties. The Fins Cover The Whole Tube & Have A Very Good Anti-Corrosive Properties. Maximum Operating Temperature For This Type Of Fin Is 350°C.
