WinterTech offers our standard Edge-Tension fin tubes available in similar or dissimilar metals. Edge tension finned tubing is recommended for moderate duty in normal ambient air applications and on most low-temperature air cooled heat exchangers.

During the manufacturing process, fin material is tightly wound around the outside of the tube to secure metal-to-metal contact of the base of  he fin with the tube. The Edge Tension Fin can also be supplied with the WinterTech-I solder or WinterTech-IB brazed fin bond.

WinterTech offers two distinct types of soldered finned tubing: root solder and solder-coated. Root soldering involves a special WinterTech technique that uses enough solder to create the bond between the tube and the base of the fin thus avoiding bridging.

Solder-coated finned tubing covers the entire fin and tube surface with the alloy.

Lead-free Tin alloys are available for all soldered products

Highly efficient yet cost effective WinterTech L-footed finned tubing offers maximum heat transfer at lower temperatures.The unique L-shape d de sign holds fins rigidly to with stand heat cycling and high velocity air vibration.

The L-Foot Finned Tube can also be offered in following variations to the Fin: Knurled Fin, Double Overlap Fin, Perforated Fin.

The Wrinkle Fin attachment is a surface variation to the Edge Tension fintube. This enhancements breaks up the air to enhance heat transfer. It uses symmetrical waves in the radial surface of the fin as it contacts the tube.

The fins are tack welded to the tube at each end of the fin section to ensure contact. The fins are also thicker sheet m etal, typically 0.030″ to 0.060″ thick, which m akes them very robust. W rinkle Fin enhancement is commonly used in heavy duty applications and rough environments.

WinterTech Low Fin (Integral) tubing is a type of extruded tubing that consist of shorrt low fins. The low fins. The low fin tube has the adventage of adding surfce area to a smooth tube while maintaining the same outside diameter.

Low fin enhanced tubes can be used in standard shell and tube baffles and tube sheets.

The WinterTech Medium-High Finned Tube is made from mono extruded copper alloys. The WinterTech-M height is within 0.140” (3.5mm). Extruded fin tube are formed helically out of a mono-metal tube.

The result is an integrally formed finned tube wiith an excellent fin-to-tube uniformity providing exceptional efficiency and longevity.
