Trane 3-D® Scroll Compressor

Simple Design with 70% Fewer Parts
Fewer parts than an equal capacity reciprocating compressor means significant
reliability and efficiency benefits. The single
orbiting scroll eliminates the need for pistons,
connecting rods, wrist pins and valves. Fewer parts lead to increased reliability. Fewer moving parts, less rotating mass and
less internal friction means greater efficiency than
reciprocating compressors.
Patented 3-D Scroll Compliance
Trane 3-D Scroll compliance provides important reliability and efficiency benefits. 3-D compliance allows the orbiting
scrolls to touch in all three dimensions, forming a
completely enclosed compressor chamber which leads to increased efficiency. In addition,
3-D compliance means the orbiting scrolls only touch
with enough force to create a seal so there is no
wear between the scroll plates. The fixed and orbiting scrolls are made of high
strength cast iron which results in less thermal
distortion, less leakage, and higher efficiencies. The
most outstanding feature of the scroll compressor 3-D compliance is that slugging
will not cause failure. In a reciprocating compressor,
however, the liquid or dirt can cause serious damage.
Low Torque Variation
The 3-D Scroll compressor has a very smooth compression cycle with torque variations that are only 30 percent of that
produced by a reciprocating compressor. This means the
scroll compressor imposes very little stress on the motor for greater reliability. Low torque variation means reduced noise and
vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and reliability is further optimized with this design.
Cool suction gas keeps the motor cooler for longer life
and better efficiency.
Proven Design Through Testing and Research
With over twenty years of development and testing, Trane 3-D Scroll compressors
have undergone more than 400,000 hours of laboratory
testing and field operation. This work combined with over 25 patents makes Trane the worldwide leader in air conditioning scroll
compressor technology.
