Fin Tubes

Fin tubes are used for the following applications:

- heating up clean air or waste gas
- cooling or de-heating of clean air or waste gas
- air cooled plants


Agetherma heat exchangers are always equipped with spirally finned tubes.

 

The core tube can either be made of stainless or carbon steel. The fin is either stainless steel, carbon steel or aluminium.

 

The choice of the type of fin and the material of the core tubes depends on the requirements of the customer and the application of the heat exchanger.

 

Agetherma GmbH uses the following types of fin tubes for the most of applications.


Type LF-Fin
is a type of spirally finned tube which consists of a circumferential stainless steel or aluminium fin which is welded spirally on a stainless steel core tube by means of a laser.

Type E-Fin
is a type of spirally finned tube where the fin is rolled from a hollow blank aluminium tube slid over the core tube by a process using pressure to create a rolled "pressure bond" between the core tube and fins.

Type G-Fin
is a type of spirally finned tube where the fin is mechanically embedded into a groove that is ploughed into the tube and locked into place by rolls that force the groove to tightly close around the fin base.

Type S-Fin
is a type of spirally finned tube where the fin is welded circumferentially on a core tube by high-frequency welding.

Type W-Fin
is a type of spirally finned tube with a fin which has a corrugated shape at the foot of the fin. It is coiled around the core tube with a certain pre-tension to ensure an ideal fin-to-tube contact. The ends of the _n are tackwelded on the tube.

Additionally there a few further types of fin tubes:


Type I-Fin
is a type of spirally finned tube where the fin is coiled around the core tube with to ensure the fin-to-tube contact. The ends of the fin are tackwelded on the tube.

Type L-Fin
is a type of spirally finned tube where the fin is coiled around the core tube with to ensure the fin-to-tube contact. The ends of the fin are tackwelded on the tube. To achieve a better contact with core tube the fin has the shape of a L.
