Kasera Fin Tube 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 metals-to-metal contact of the base of the fin with the tube.
Integral Low Fin Tube has the advantage that it can improve the thermal performance of a Heat Exchanger without the necessity for changing shell size, flow arrangement or the repositioning of piping.
The external surface of the tube is increased by the formation of "low fins" by direct extrusion from the material of the base tube. In general, for a given heat transfers only one half of integral fin tubes are needed as would be required for bare tubes. This effectively saves more than 30 percent on tubes alone.
