Daikin Applied Introduces High-Efficiency Water-Cooled Chiller

Daikin Applied introduced Magnitude WMT, a next-generation magnetic bearing centrifugal chiller able to deliver energy efficiency at all points of operation. WMT is designed for the ultra-low global warming potential refrigerant R-1233zd(E). The chiller features oil-free magnetic bearing technology and a two-stage compressor.

With only one main moving component, the oil-free design reduces friction and potential points of failure, which simplifies maintenance and extends the life of the equipment. A two-stage impeller layout is enhanced by a refrigerant economizer. The dual-stage setup maximizes part-load performance. With full-load efficiency of 0.50 kilowatts per ton and part-load efficiency of 0.30 kW/ton, the WMT is up to 40% more efficient than standard centrifugal chillers.
