Features and Benefits

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 compression chamber that 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—resulting 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, 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 are further optimized with this design. Cool suction gas keeps the motor cooler for longer life and better efficiency.

Proven DesignThroughTesting 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 makesTrane the worldwide leader in air conditioning scroll compressor technology.
