Johnson Controls Inc. has enhanced its portfolio of commercial and residential HVAC/R products with the expansion to 1,000 tons of cooling for its magnetic-bearing centrifugal chiller line, the YORK YMC. The larger cooling capacity units address the need for reduced sound, high efficiency and low maintenance while advancing the future of chillers through magnetic bearing and oil free technology. The chiller uses magnetic levitation technology in its driveline to spin without friction, offering a quieter, more efficient operation.

The YMC2 also has a standard variable speed drive to further increase the efficiency of the chiller. Sound levels as low as 70 dBA for quiet operation, the same sound level as a vacuum cleaner. YORK chillers are known for utilizing low entering condenser water temperature to reduce energy usage.

The YMC2 chiller is capable of achieving values below 0.1 kW/ton at part load, resulting in a significantly lower utility bill. The oil-free design delivers reliable operation and low maintenance, providing a lower total cost of ownership over the life of the chiller. The complete YMC2 line now offers units from 165 - 1,000 tons (580 kW to 3,500 kW).
