Trane’s Spine Fin line or products are the preferred choice for shore home and business owners!

Corrosion resistance begins with
the manufacturing process.
Trane manufactures Spine Fin on patented high-speed machines that cut, form and wrap aluminum fin stock around aluminum tubing. The tubing rises through a colored adhesive bath in the center of the machine, which coats the tube. Tension rollers wrap the ribbons tightly to the tube using the bonding adhesive. A seam of the adhesive extrudes between the fin wraps, which not only locks the fin stock on the tube, but also forms a protective barrier against moisture and

US Navy research testimony
In a corrosive environment (coastal or urban), heat exchanger performance can degrade quite rapidly. According to an unbiased study performed by the United States Navy Civil Engineering Laboratory, Naval Construction Battalion Center in Port Hueneme, California, evidence of the fact, and support of all aluminum coils in such environments is presented. Technical Report #N-1560 observes that after 24 months, aluminum tube/ aluminum fin, heat exchangers are performing 32% better than copper tube/aluminum fin units.

A protective cabinet prevents damage.
The outdoor coil in an air conditioner or heat pump can easily get damaged in a backyard environment. Lawn equipment, damaging hail, even baseballs, sticks and tree limbs can all add years of wear and tear to a heat exchanger. Trane’s protective cabinet design prevents coil damage by encasing the heat exchanger in heavy gauge steel louvered panels. These panels allow air to pass through the cabinet, but seal out dangerous external elements.
