LG Raises the Bar with its Revolutionary Oil Free Inverter Centrifugal Chiller
2016/11/27
Air-bearing technology is used in a number of other high-tech devices such as industrial gas compressors, compact gas turbines and airplane refrigerant circulation systems. By including this cutting edge technology in its oil free inverter centrifugal chiller for the first time, LG is able to offer a unit with exceptional performance, incredible efficiency, and low operational costs. Utilizing refrigerant instead of an electromagnetic field, the LG oil free inverter centrifugal chiller features a simple structure and is easier to operate than conventional magnetic bearing units.
 
The new LG oil free inverter centrifugal chiller achieves the industry’s highest energy efficiency rating thanks to its effective three-level inverter and two-stage compression cycle. This allows the LG oil free inverter centrifugal chiller to register an integrated part load value (IPLV) of 11.3 while simultaneously recording a 6.4 coefficient of performance (COP). The use of LG’s oil free inverter technology results in operating costs that are 29% lower than traditional screw chillers. LG oil free inverter centrifugal chiller also boasts a high speed direct connection, a closed impeller and variable diffusers which allow for it to operate at just 74dB.
