Fin Type: Laser Welded Finned coil Tube: copper, steel or stainless steel Fins: aluminium, copper, steel or stainless steel Fin Tube Length: No Limit Product description：Finned tube coil are available in many products like air heaters, air coolers, condensers, heat exchangers and evaporators for HVAC and various other industrial applications. What is finned tube coil Finned tube coils are commonly used for gas-liquid exchange. Heat transfer on the gas side is usually much lower than on the liquid side, and heat sinks are required on the gas side. The outer fins of the tube may be normal on a single tube, or maybe transverse, spiral, or longitudinal. Longitudinal fins are commonly used in a double tube or shell heat exchangers without baffles. A fluid may be a gas or a viscous liquid. Our finned tube coil products range from small applications to large commercial and industrial projects.
