Compound finned tubes (extruded high fins) are the general standard on
the
AB&CO Process Air Heaters for high temperature applications -
such as steam, thermal fluid (hot oil), hot pressurised water etc. For cooling /
dehumidifying and moderate temperature applications, the fin coils (tubes expanded stack
of fin plates) are the general standard. However other types of finned tubes are avaiable on request - for both heating and cooling applations. These alternatives are used for special circumstances e.g. critical temperatures and corrosive environments, but they are also chosen for economical reasons. Below is listed the most common type of finned tubes that can be offered on AXA Air Heat Exchangers. |

Details of the Design This fin 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. These extruded fin in this particular design offers excellent corrosion protection of the base tube. Maximum operating temperature for this fin type is 290 - 300°C.
