Spine Fin™ Coil

All aluminum outdoor coil that features the patented Spine Fin™ design. Spine Fin™ consists of thousands of tiny spines bonded to continuous aluminum refrigerant tubing. The tiny spines create a greater surface area, helping it to transfer more heat from your home, more efficiently. It provides greater heat exchanging capabilities (meaning higher efficiencies) and is more resistant to corrosion than traditional copper/aluminum.
