LL FIN

In LL-type fin, unlike L-type, the two fin feet are overlapped so as to completely enclose the base tube and ensure an excellent resistance to corrosion.

This type of finned tube is often used as an alternative to the more expensive extruded fin in corrosive environments.

Operating temperature: 180°C.
