Lowest Total Cost Of Ownership

Exceptional efficiency means the YMC² uses less energy, lowering operating costs. And fewer moving parts means lower maintenance costs.


An unequaled range of operation allows for continuous performance under conditions that would normally shut down other chillers.


The full chiller design results in very low sound levels.

Reduced Footprint

YMC² chiller offers compact design with a shell option of 8 feet.


  • Stable operation with entering condenser water temperatures 30°F (16.7°C) below leaving chilled water set point
  • Offers exceptional efficiency with below 0.100 kW/ton at part load
  • Less complex magnetic-bearing technology for superior reliability and performance compared to refrigerant-lubricated, ceramic ball bearings
  • Fully integrated, lubrication-free and oil-free design
  • Lower total cost of ownership, competitive first cost, low maintenance and operating costs thanks to fewer moving parts
  • YMC² is OSPHP seismic certified to meet seismic safety requirements

More control – More protection – Better records
