LG developed its unique LeviTech chiller technology by starting with the smallest individual components and treating each constituent part as the centerpiece of the entire project. This unrivaled attention to detail makes LeviTech an oil-free chiller technology like nothing that has come before. LG manufactures both magnetic-bearing and air-bearing centrifugal chillers, the first in the world to produce the latter. Both types of chillers are equipped with advanced technologies that eliminate friction, greatly increasing their energy efficiency. In the more common magnetic-bearing chillers, powerful magnets keep the shaft afloat to create a completely frictionless state, whereas air-bearing chillers rely on increased pressure in the refrigerant gas-filled housing of the compressor to open the leaf foil wider. This creates an air gap between the shaft and leaf foil assembly, allowing for frictionless operation. LG’s LeviTech oil-free line-up boasts a wide capacity range as its air-bearing chillers are ideally designed for smaller spaces while its magnetic-bearing chillers excel in larger settings.
LG’s lineup of LeviTech oil-free VSD Centrifugal Chillers also achieves world-class energy efficiency ratings thanks to its innovative VSD compressor technology. The use of LG’s oil-free LeviTech VSD technology results in lower operating costs while significantly reducing maintenance expenses by eliminating the oil management system. Furthermore, the new oil-free VSD Centrifugal Chillers employ a high speed direct connection that allow for operation at a mere 73dB(A).
In keeping with LG’s record of technological innovation, the UPS supplies constant power to the magnetic bearings and controller regardless of input fluctuations or power shortages, protecting them against potential damage during power failure. The solution’s black box records performance issues as they occur, making service tune-ups simple and straight forward. These and other tangible benefits separate LG’s lineup from the competition, opening up the chiller market like never before.
In addition, LG’s oil-free LeviTech-equipped VSD Centrifugal Chiller lineup offers capacities ranging from 100RT to 1,100RT that can be installed to serve not only small to large sized buildings but also to provide specialized climate control in demanding projects ranging from ice storage to district cooling.
