“Get Your Fix” Part 4 of 10: Trane® RTAC, RTAA and CGAM
Back to our top ten commercial OEM condenser coils that have had issues while in service over the past decade. Coming in fourth is the Trane RTAC, RTAA and CGAM series.
Among the usual suspects of OEM condenser coils seeing frequent operational issues is Trane’s RTAC, RTAA and CGAM series.
Trane introduced their RTAA and RTAC series in 1994, and their CGAM series in 2009. No doubt, these high-performing, commercial-grade chillers were built to last, and we continue to see them supporting air systems in schools, hospitals, retail spaces and office buildings. As the years have gone on, these massive chillers have required more frequent repair.
Additionally, Trane began manufacturing some chillers in their CGAM series with all-aluminum microchannel condenser coils. Combine the general aging of the equipment with lower-grade microchannels, and we get called to build replacement coils for Trane’s RTAC, RTAA and CGAM series all the time. So much so, Trane replacement coils have become our specialty and our experience with them is second to none.

An Extensive OEM Drawing Database
We sold our first replacement condenser coils for Trane’s RTAC, RTAA and CGAM series over ten years ago. Throughout this time, we have perfected the drawings and manufacturing to make ordering and installation of these coils as seamless as possible. Today, our database of Trane coil part numbers (COL numbers) is one of the most comprehensive in the replacement coil industry and it continues to grow daily.
It’s time to #changethechannel
Should you have a Trane chiller that was manufactured with an all-aluminum microchannel, it’s at higher risk for premature MCHX coil failure, which can be caused by unit vibration and excessive refrigerant leaks.
Our #changethechannel program gives you the option to convert the all-aluminum microchannel to a more durable and efficient copper tube microchannel. Upgrading to a copper tube, aluminum fin coil is an efficient, cost-effective way to making your system more reliable and easier to service while maintaining the OEM efficiency.
Microchannel Conversion Tip: From our experience, chillers of this size deserve the uncompromising strength and durability of copper coils. To combat unit vibration and tube sheet leaks, we recommend using the thicker .020” copper tube wall. However, should you need a more economical coil, a .016” copper tube can be used, as well.
