YORK YZ Chiller

The YORK 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. Compared to traditional fixed-speed oil-bearing chillers, the YZ delivers up to 35% annual energy savings.
 
The YZ chiller can deliver significant energy savings and lower operating costs by taking advantage of the off-design conditions where chillers operate 99% of the time. The YZ operates with entering condenser water temperature as low as 40°F (4.5°C), providing enhanced performance in every operating condition and the widest operating envelope in the industry. The YORK YZ uses an optimized single stage design to provide industry-leading real-world energy efficiency. The chiller can also operate with condenser temperatures below the evaporator temperatures, eliminating the need for a water-side economizer, which simplifies the system, requires less mechanical room space, and saves money on components, piping, controls, and maintenance.
