The Wrinkle Fin attachment is a surface variation to the Edge Tension fin tube. 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 metal, typically 0.030″ to 0.060″ thick, which makes them very robust. Wrinkle Fin enhancement is commonly used in heavy duty applications and rough environments.
