Aluminum fin tube contains Type L, LL, KL, Type G and extruded fin Tube
Manufactured in the same way as the 'L' aluminum fin tube type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of aluminum fin tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.

Manufactured exactly as the 'L' aluminum fin tube 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.

The aluminium fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures.

Extruded Fin Tube
This aluminium fin tube type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube.
