Features & Benefits
Core Technology
Performance
Improved Suction Path
The simple structure of the suction path reduces the heat transfer and
discharges temperature, boosting both volumetric efficiency and performance.
Optimized Wrap Design
A wrap design minimizes dead volume
and Reduces compression loss.
Better Alignment
The new scroll alignment design reduces tilting and friction loss at low load,
resulting in efficiency improvement compared to the conventional model.
Improved Motor Design
New core design, load & torque optimized motor.
Bearing
New PTFE bearing improves reliability.
Smooth Starting
New design reduces starting load by equalizing pressure inside the compressor.
Oil Management
Oil Drain channels lead the oil away from the turbulence and
along the shell, reduce oil circulation ratio.
Low GWP Refrigerant
Keeping up with the latest eco-friendly standards,
LG Gen 3 series of Scroll Compressors are compatible
with low GWP refrigerants like R32 and R454B.

US Business History
As a dominant player in the USA market since 2006,
LG’s Scroll Compressors have consistently stayed
ahead of market regulations. Top-of-the-line signature models
ensure ongoing compliance and optimum performance.
Technical Support Center in US
Located in the Dallas metropolitan area, our technical support center has an advanced technological
testing chamber and innovative processes that are used for breaking down compressors into individual parts.
This allows for the physical inspection that is necessary to diagnose and improve our designs.
At LG, we are proud of our industry-leading tear-down analysis capabilities and numerous function tests.
In order to support quality assurance throughout North America, we run tests such as circuit resistance,
insulation resistance/HiPOT, and no load/load.
Functional Testing
Tear Down Analysis
- Electrical Test
- Start-up Test at Actual Load
- Voltage Fluctuation
- Run Test at Various Conditions
- Protection Device Evaluation
- Scroll and Rotary
Applications
Designed for both residential and commercial use, the Gen 3 Scroll Compressor
is a great choice for multifamily, mixed use, and other spaces.
Dimensions
The Gen 3 frame size is nearly identical to the previous model.
Its similar size and design makes it easy for users to upgrade, as OEMs won’t need to redesign
their conventional systems and installers will find compatibility when replacing existing compressors.
