Air Cooled Aluminum L-Foot Tension Wound Finned Tubes
Tex-Fin Aluminum L-Foot Tension Wound Finned Tubes are an
economical solution for applications requiring greater resistance
to vibration and heat cycling typical of air cooled heat
exchangers. The L-Foot design mechanically locks the fins and
provides broader contact surface between tube and fin.
Tube Sizes: | 1/2" O.D. to 2" O.D. |
Fin Heights: | 1/4" to 5/8" |
Fin Pitch: | 4 to 13 fins per inch |
Air Cooled Embedded Finned Tubes
Tex-Fin Embedded Fin Tubes offer solutions where higher
temperatures, continuous thermal cycling and tube vibration due to
high velocity air streams can cause failures. The fin is
mechanically embedded into a groove that is plowed in the tube O.D.
and is locked into place by rolls that force the groove to tightly
close around the fin base.
Tube Sizes: | 9/16" O.D. to 2" O.D. |
Fin Heights: | 1/4" to 5/8" |
Fin Pitch: | 5 to 13 fins per inch |
Air Cooled Extruded Finned Tubes
Tex-Fin Extruded Finned Tubes provide the greatest resistance to
atmospheric corrosion. The aluminum fin material completely
encloses the tube, except at the ends where a tube coating can be
applied. Where atmospheric corrosion is present and when operated
within design temperature limits, extruded finned tubes provide the
most stable performance over time as compared to the other fin
types. The fin is rolled from an outer aluminum tube by a process
using pressure to create a rolled "pressure bond" between the liner
tube and fins.
Extruded Finned Tubes are commonly used in applications with
temperatures up to 550 degrees Fahrenheit.
Tube Sizes: | 1" O.D. to 1 1/4" O.D. |
Fin Heights: | 1/2" to 5/8" |
Fin Pitch: | 8 to 11 fins per inch |
