KL-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.

Fin material: Aluminium or copper.

Tube materials: No theoretical limits.
