These finned tubes have fins made of wire instead of strips. Continuous loops of wire are formed and are continuously soldered to the circumference of the tube to ensure 100% contact. Loops per turn and turns per foot can be altered as per surface area requirements. Due to continuous soldering of wire loops these finned tubes offer a very high heat transfer efficiency with less air pressure drop.
