The compressor features improvements influenced by feedback from OEMs and leading service technicians looking for performance and reliability. The R1 compressor will be launching exclusively with a manufacturer in late spring.

The R1 compressor, jointly designed by the LG Component Solutions Engineering and Quality center in Farmers Branch, Texas, and LG’s R&D Center in South Korea, is engineered for energy-efficient operation in residential and light commercial applications such as single-family homes, apartments and multi-family residential units. It has evolved from LG’s traditional scroll compressor and rotary compressor, providing efficiency improvements including a hybrid scroll wrap and a mid-bearing scroll assembly that reduces tilting movement thereby reducing energy use.

Suited for a variety of demanding environments, the R1 family of compressors (from 2- to 5-ton models) offers temperature and humidity control across and can be paired with VFDs from various OEMs and LG. The compressors provide longer run cycles, which allows opportunity for improved air quality. The structure also provides a shorter oil path to the upper bearing surface, decreasing the likelihood of oil loss.

Designed for the North American residential market, the compressor has an operation range of 10-150HZ, offering a 15:1 turn-down ratio. With LG’s mechanical efficiency, it features an overload protector that prevents damage in abnormal conditions, copper stubs for brazing, and precision-calibrated bypass valves that facilitate start-up ease by relieving pressure and protecting against over-compression.
