The York YZ magnetic bearing centrifugal chiller won the 2019 AHR Expo Innovation Award in the Cooling category. Manufactured by Johnson Controls, the fully-optimized chiller is built with low-global warming potential (GWP) refrigerant to increase energy efficiency.

The York YZ provides centrifugal-chiller energy efficiencies as low as 0.1 kW/ton and has the potential to reduce annual electricity consumption by an average of 35 percent. Designed with engineering optimization for every component around R-1233zd, it combines technologies including a variable-speed magnetic bearing compressor, high-speed hermetic induction motor, falling film evaporator, adaptive capacity control logic and cloud-based analytics.
