High Efficiency Magnetic Bearing Centrifugal Chiller

Technology / Service Summary

Magnetic bearing centrifugal chiller is designed with oil free system, resulting in eliminating oil contamination in the refrigerant and heat transfer surfaces to provide outstanding efficiency.


Daikin’s High Efficiency Magnetic Bearing Centrifugal Chillers have been
installed in Hotels, Shopping malls and district cooling of Smart City.


1.Low Noise
The chiller sound pressure level is as low as 77.5 dB. This quiet operation makes this ideal option for sound sensitive environments such as schools, concert halls and museums.
2.Compact Design
The compact size of the chiller makes it available for replacement, retrofit and energy upgrade projects. In addition, the smaller footprint saves the chiller plant room space.


1.Energy Cost
Reduced annual energy costs due to outstanding part-load efficiency since chillers spend about 99% of their operating hours at part-load conditions.
2.Operational Cost
Magnetic bearing chiller is oil free system without any need for oil charge, oil replacement, oil
filter replacement, etc. The results are reduced operational costs and maintenance savings every year.
