What’s New
The RTAC offers the same high reliability of Trane’s previous air-cooled helical rotary design coupled with lowered sound levels, increased energy efficiency, reduced physical footprint due to itsadvanced design, low speed/direct drive compressor and proven Series R performance. Some of the major advantages of the Model RTAC are: • Over 99% reliable • Lower sound levels • Higher energy efficiency • Smaller physical footprint • HFC-134a optimized design The Series R Model RTAC is an industrial grade design built for both the industrial and commercial markets. It is ideal for schools, hospitals,retailers, office buildings, Internet service providers and industrials.

ASHRAE Standard 90.1 andRTAC World Class Energy Efficiency…
The importance of energy efficiency cannot be understated. Fortunately, ASHRAE has created a guideline emphasizing its importance. Nonetheless, energy is often dismissed as an operational cost over which the owner has little control. That perception results in missed opportunities for energy efficiency, reduced utility bills, and higher profits. Lower utilitybills directly affect profitability. Every dollar saved in energy goes directly to the bottom line. Trane’s RTAC is one way to maximize your profits. ASHRAE Standard 90.1 & Executive Order - New technology applied to the design, controls, and manufacturing have created excellent efficiency levels in the RTAC that are helping to push industry minimums to new heights.
