Manufacture: A core tube is fitted into an aluminium primary tube. This assembly is then fed into the triple-spindle finning machine. Three special multi-disc packs extrude the aluminium tube into helical high fins while reducing the inner diameter to give firm pressure contact with the core tube.

G-Fin Tube is an aluminium fin stripped tube, which is wounded 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
