Finned tubes are used wherever electricity is generated or raw material is refined and efficient cooling is required. Finned tubes are used in condensers, coolers and furnaces. The larger surface area means that fewer tubes are needed compared to the use of plain tubes. The higher efficiency of finned tubes thus enables significant space and cost savings.
| Surface expanded tubes are available in various materials and designs: | |
|---|---|
| „G“ (Embedded) | „I“ |
| „L“ (L-Fin) | „N“ (Low Fin) |
| „KL“ (KL-Fin) | „M“ (Medium Fin) |
| „DL“ / „LL“ (DL/KL-Fin) | „LFW“ (Longitudinal Channel Fin) |
| „HY“ (Extruded) | „LFS“ (for Boiler wall constructions) |
| „HYS“ (Extruded Serrated) | „S“ (Square Fin) |
| „WO“ (Welded On) | „Double S“ (Rectangular Fin on 2 tubes) |
| „WOS“ (Welded On Serrated) | Studded Tubes |
