International. Johnson Controls announced that it has expanded its line of magnetic bearing centrifugal chillers, the YMC2 York, to 1,000 tons of cooling (3,500 kW). Larger cooling capacity units address the need for sound reduction, high efficiency and low maintenance, as well as feature magnetic bearings and oil-free technology.
The chiller uses magnetic levitation technology in its transmission to rotate frictionlessly, offering quiet and efficient operation. The YMC2 also has a standard variable speed unit to further increase efficiency.
The chiller is capable of reaching values below 0.1 kW/ton at part load, resulting in a significantly lower utility bill. The oil-free design provides reliable, low-maintenance operation, delivering a lower total cost of ownership over the life of the chiller.
The complete YMC2 line now offers units from 165 to 1,000 tons (580 kW to 3,500 kW).
