The new Trane Model RTAC Air-Cooled
Helical-Rotary Chiller is the result of a
search for higher reliability, higher
energy efficiency, and lower sound
levels for today’s environment.
In an effort to reduce energy consumed
by HVAC equipment and to continually
produce chilled water, Trane has
developed the Model RTAC chiller with
higher efficiencies and a more reliable
design than any other air cooled chiller
available on the market today.
The Model RTAC chiller uses the proven
design of the Trane helical-rotary
compressor, which embraces all of the
design features that have made the
Trane helical-rotary compressor liquid
chillers such a success since 1987.

What Is New
The RTAC offers the same high
reliability coupled with greatly improved
energy efficiency, vastly reduced
physical footprint, and improved
acoustical performance, due to its
advanced design, low-speed, direct-
drive compressor, and proven
Series R™ performance.
The major differences between the
Series R, Model RTAC and Model RTAA
are:
• Smaller physical footprint
• Lower sound levels
• Higher energy efficiency
• Designed specifically for operating
with environmentally-safe HFC-134a.
The Series R Model RTAC helical-rotary
chiller is an industrial-grade design, built
for both the industrial and commercial
markets. It is ideal for schools, hospitals,
retailers, office buildings, and industrial
applications.
