Features and
Benefits
Superior Full Load Efficiency
Precise Rotor Tip Clearances
Higher energy efficiency in a helical
rotary compressor is obtained by
reducing the rotor tip clearances. This
reduces the leakage between high and
low pressure cavities during
compression. Precise rotor tip clearance
is achieved with the latest manufacturing
and machining technology. Trane is the
first helical rotary compressor
manufacturer to electronically check
compressor parts machining accuracy as
part of the standard production process.
Optimized Compressor Parts Profiles
Rotor and slide valves are unique
designs, optimized for the air
conditioning application. The rotors are
designed for the pressure ranges in the
air conditioning application. The unloader
valve has a unique profile that resulted
from computer performance modeling in
typical part-load situations.
Advanced Heat Transfer Surfaces
Condenser and evaporator tubes use the
latest heat transfer technology for
increased efficiency.
Great Part Load Efficiency

Screw Compressors and
Electronic Expansion Valve
Trane Helical Rotary Screw Compressor
Means Superior Part Load Performance
The air-cooled Series R
™
chiller has great
part-load performance. The combination
patented unloading system on the
“general purpose” compressor utilizes
the variable unloading valve for the
majority of the unloading function
similar to that of the slide valve. The
“general purpose” compressor also
uses a step unloader valve which is a
single unloading step to achieve the
minimum unloading point of the
compressor. The result of both of these
designs is optimized part-load
performance far superior to single
reciprocating compressors.
