Trane’s proprietary coil design, Spine Fin, has proven to be superior to any other technology. The Spine Fin is the amazingly efficient outdoor coil in a Trane air conditioner. It incorporates thousands of tiny spines bonded to continuous aluminum refrigerant tubing for more efficient coil. By using all aluminum in the tubes as well as the fins, it have more corrosion resistant, longer lasting outdoor coil. It is durable even in coastal and industrial locations where corrosion might mean a coil replacement in less than three years. Features  Unique configuration requires no end turns.  Internal grooves of Spine Fin stir the refrigerant, enhancing    heat transfer.  Patented transition joints reduce leaks.    (leak rate of less than .05 % on Spine Fin).  Four side configuration presents a large surface area    to the outdoor airstream.  Spine Fin has 90% fewer brazed joints.  Spine Fin is manufactured on patent high speed machines.       back Home | Small Business / Retail | Restaurant | Hospital | Hotel | Education | Life Science
