The LG UniRotary™ Compressor, featuring innovative technology, is designed to deliver reliable performance in unitary systems.
LG's UniRotary™ compressor in black with metallic accents is highlighted under lighting.
Our UniRotary™ Compressors feature a design with check valves and solenoid valves, providing reliable restarts and outstanding durability.

LG UniRotary™ Compressor is engineered to withstand harsh restarts, significantly enhancing motor durability and ensuring long-lasting performance in unitary applications.
The UniRotary™ Compressor features a check valve that prevents high pressure from entering when off, helping to maintain stable pressure and allowing a gradual rise in temperature. This design enhances overall stability and boosts the SEER rating.
Our UniRotary™ Compressor's solenoid valve quickly adjusts the pressure between the main unit (A) and accumulator (B), enabling rapid restarts and instant cooling. Unlike conventional systems, this ensures faster and smoother system reactivation.

What is benefit of UniRotary™ Compressor?
The UniRotary™ Compressor uses a check valve and solenoid valve to enhance reliability. Designed for unitary products, it improves SEER rating and ensures high reliability for all applications.
How does the SEER rating improve?
UniRotary™ Compressor prevents high or low pressure equalization when set to "compressor off" by taking advantage of residual cooling.
Why is a solenoid attached to the pipe connecting the body and accumulator in a UniRotary™ Compressor?
The solenoid valve in a UniRotary™ Compressor rapidly adjusts the pressure between the accumulator and the body, minimizing restart time and enabling quick operation.
