YZ Magnetic Bearing Centrifugal Chiller
150-1,550 TR (530-5,450 kW)
The YORK® YZ challenges conventional, water-cooled chiller design to deliver superior performance, lower cost of ownership and a new definition of sustainability.
- Innovative design with magnetic-bearing driveline
- Variable-speed drive centrifugal compressor
- Low global warming potential (GWP) refrigerant R-1233zd(E)
Fully Optimized for Ultimate Performance
The YORK® YZ Magnetic Bearing Centrifugal Chiller is a revolutionary advancement that challenges everything about conventional chiller design. Built upon decades of industry-leading chiller expertise, our engineers questioned every component and challenged every assumption. The result is the first chiller fully optimized for ultimate performance with a next-generation, low-GWP refrigerant, delivering exceptional efficiency and operation. It’s the first chiller built to exceed every expectation.
Features
- With variable-speed drive, a variable-geometry diffuser and magnetic-bearing technology YORK® YZ delivers up to 35% annual energy savings versus traditional, fixed-speed, oil-bearing chillers
- Robust and reliable high-speed, hermetic induction motor reduces maintenance
- This low-pressure chiller has been fully optimized around R-1233zd(E), which has a GWP of 1 and an A1 ASHRAE safety classification
- Data can be securely connected to analytics platform for remote monitoring and predictive diagnostics
- Patented capacity control technology provides rapid response to the load on the building, ensuring the YZ does not waste energy or work harder than needed
- Magnetic-bearing driveline offers outstanding reliability and 80% fewer moving parts than traditional oil- or refrigerant-lubricated drivelines
- Optimized, single-stage compressor design provides best real-world energy efficiency and the widest operating range at off-design conditions
- OptiView™ Control Panel with connected service offers 100 set points, readouts, alerts, trending reports and more
- Patented falling-film evaporator design reduces refrigerant charge up to 60%, and reduces evaporator shell size up to 20%
