3 Air-cooled scroll chiller
Balancing energy effi ciency
and quiet operation
Energy effi ciency, sound, reliability, controls and
service are all vitally important to the effective
operation of a building. Trane engineers know
how important all these factors are to you—so
we designed them all into our new 20-130 ton
model CGAM chiller. Using the best elements of
each design we created an extremely quiet and
highly effi cient chiller.
High effi ciency and quiet operation
Most air-cooled chillers require you to choose
between a highly-effi cient unit or a low-noise
unit. A quieter fan often produces less air fl ow,
reducing effi ciency. With the Trane CGAM chiller,
we have designed these two very important
benefi ts into one chiller.
Our design team compiled the best approaches
from around the globe to optimize the CGAM
chiller so that it meets global green initiatives
and ASHRAE energy effi ciency standards.
The Trane CGAM chiller is one of the most
effi cient air-cooled chillers, even among screw
compressor equipment. Low sound levels are
standard, with a 5–8db reduction compared to
previous Trane air-cooled chiller models. And,
with factory-installed attenuation, Trane further
reduces sound levels—up to an additional 3db.
Reliability you can count on
Energy effi ciency and quiet operation are
increasingly critical. As a result, we perform
extensive testing on the compressors and units,
confi rming their robust design and durability
while ensuring our high standards for reliability.
Our testing includes:
• Extreme testing includes cold ambient starts,
hot water starts and high ambient operation
• Compressor accelerated life cycle testing,
including high pressure ratio, high load test,
fl ooded starts/stops, start/stop testing
and phase reversal
