The new system is an oil-and-contact-free drive solution for centrifugal compressors in chillers. Combining a high-speed
permanent magnet motor and active magnetic bearings with integrated controls, the magnetic system can operate with variable
speed drives to deliver energy savings of at least 10% compared to conventional centrifugal compressor designs, LG stated.
The new magnetic bearing centrifugal chiller lineup is suitable for green building application. The chiller boasts
excellent efficiency of COP 7.0 and IPLV of 12.0 at AHRI conditions. Additionally, the lineup offers a capacity range of
260 RT to 1100 RT for single compressor and from 520 RT to 2200 RT for dual compressor based on conditions of the Air
Conditioning and Refrigeration Institute (AHRI) standard.
Yong Geun Choi, president of LG Electronics Gulf, said: “Our next-generation solutions are what the HVAC industry needs
today. With the rise of smart cities and green buildings in the UAE and in the region, the demand for the best solutions
places LG at the forefront of the nation’s most promising residential, commercial and industrial applications. We are
committed to products that are not only cutting edge and durable, but also strictly comply with the nation’s energy
efficiency regulations laid down by government and green building policy makers.”
The innovative LG technology also reduces maintenance costs for the user and provides reliable and cost-effective air
conditioning, the company said.
