Johnson Controls has extended the capacity range of its YORK YZ Magnetic Bearing Centrifugal Chiller to include chillers beyond 1,000 tons (3,516 kW), now up to 1,350 tons (4747 kW) of refrigeration.
First introduced in early 2018, the YZ Chiller, fully optimized for next generation low-global warming potential (GWP) refrigerant—R-1233zd(E), was launched with a capacity range of 165 to 1,000 tons (580 to 3516 kW).
The extended capacity YZ Chiller uses an integral, variable speed drive and advanced magnetic bearing technology that features a single moving assembly suspended in a magnetic field that does not require lubrication. This technology requires 80% fewer moving parts than traditional oil or refrigerant-lubricated drivelines. The result is enhanced reliability, reduced maintenance and improved efficiency.
