L Fin:
L- shaped strip gives optimum contact pressure of the fin footonto the base tube thus improving the theat transfer efficiency.
This also gives considerable corrosion protection to the basetube.
* Maximum Working Temperature: 270 °F(130°C)
* Fin Materials: Aluminium, Copper
LL Fin:
Same as L Fin except the fin foot is overlapped giving morecorrosion protection. This type of finned tube is often used as
an alternative to the more expensive extruded type fin incorrosive environments.
* Maximum Working Temperature:330 °F(165°C)
* Fin Materials: Aluminium, Copper
KL Fin:
Same as L Fin except that the base tube is knurled before ap-plication of the fin foot.
After application, the fin foot is knurledinto the corresponding knurling on the base tube thereby enhancing the bond
between the fin and tube, resulting in improved teat transfer characteristics.
* Maximum Working Temperature: 500 °F(260°C)
* Fin Materials: Aluminium, copper
