Daikin Industries: Magnetic Bearing ChillerMagnetic Bearing Chiller Technology is now available on chillers up to 1,500 ton in capacity through an expansion of its popular Magnitude centrifugal chiller line. With more than 3,000 installations globally, Magnitude’s oil-free, magnetic bearing compressor technology reduces maintenance costs because there are no conventional bearings or an oil management system. Sustainable efficiency and capacity is assured by the oil-free system design, which maintains “as new” performance by eliminating the heat transfer loss when oil contaminates the refrigerant and builds up in the evaporator. Magnitude also meets Leadership in Energy and Environmental Design (LEED)-certification criteria by using a refrigerant, hydrofluorocarbon (HFC)-134a, with no ozone depletion potential or a phaseout schedule. Also new to the market for mission-critical applications is the exclusive Daikin Applied RideThrough™ feature, which enables the chiller to maintain compressor rotation in the event of momentary power loss. RideThrough makes it possible for the chiller to virtually eliminate the impact of short-duration power failures by “catching” the spinning motor rotor and returning immediately to the original pre-power loss capacity. In addition, the Magnitude chiller includes dual compressors and variable frequency drives (VFDs) for redundancy, allowing it to operate at 60 percent capacity on one compressor. The chiller will be available in a breakdown configuration for retrofit or applications with tight access constraints. The Daikin Magnitude centrifugal chiller line is now available in capacities ranging 100-1,500 ton.
