Efficiency
Heat transfer is one of the most important factors in achieving heating and cooling efficiencies. Trane’s proprietary coil design, Spine Fin,® has proven to be superior to any other technology.
Extensive research and development have lead to the innovative heat transfer characteristics of radiating finned, all-aluminum Spine Fin® coil heat exchangers. And, more than 40 years of realworld application experience have confirmed Spine Fin’s long-lasting effectiveness and work-horse durability. Trane continues its tradition of excellence in heat transfer by focusing on the basics of success: always using modern and innovative technologies; only using similar metals and proven materials; and, maintaining our notably high standards in the manufacturing process.

In a typical year, Trane will produce more than 26,000 miles of Spine Fin® coil – that’s enough Spine Fin® to go around the world.
We Continue To Push The Envelope.
Trane began full-scale production of Spine Fin® coils for use in outdoor products in 1968. After years of success, Spine Fin® has reached a legendary status in the industry. In fact, 
today it ranks as the most efficient heat exchanger currently being manufactured.
But at Trane, we’re not known for resting on our laurels. Our engineers and product specialists continue to push the envelope in heat transfer technology, constantly looking for greater efficiencies and more durable processes. For example, our new woven coil technology has proven to provide ultra levels of efficiency in our high-end air conditioners and heat pumps, clearly paving the way for even
greater consumer acceptance and a further reduction in the use of fossil fuels. In fact, Trane again made history, by rolling out an air conditioner with a SEER level of 19.50 in the first quarter of 2003.
Consumers Expect Efficiency From Trane.
Why is maintaining long term efficiency important? When replacing an air conditioning or heat pump system, consumers can significantly save on their cooling bills by purchasing a more efficient system than they currently have. However, the unfortunate reality is the efficiency of their new system will decline over time, as will their savings. That’s why Spine Fin’s ability to retain a system’s efficiency over the course of its lifetime is so significant. Not onlyis a Trane system efficient to operate today – but it maintains that efficiency during its years of service to the homeowner. And, that’s the Spine Fin® difference. Consumers have come to expect a higher standard of efficiency and durability from Trane products. Spine Fin® helps us fulfill this expectation.
