Magnetic-Bearing Centrifugal Chillers include low-capacity units.

Press Release Summary:

Available in low-range capacity versions extending to 165 tons, YORK magnetic-bearing centrifugal chillers (YMC2) are designed for efficiency with integrated part load value (IPLV) as low as 0.304 kW/ton at AHRI conditions. Sustainability is supported via use of R-134a refrigerant, and noise due to operation never exceeds 73 dBA. Additionally, flexible operation enables chiller to adapt to system condition changes of each facility and exceed cooling needs.

Original Press Release:

Johnson Controls Extends Capacity of YORK Magnetic-Bearing Centrifugal Chillers to 165 tons/580 kW

MILWAUKEE – Johnson Controls continues to expand its YORK magnetic-bearing centrifugal chillers (YMC2) offering with new, low-range capacities that extend to 165 tons/580 kW. With the addition of these lower capacities, the complete range of the YMC2 encompasses units from 165 – 600 tons (580kW to 2,110 kW).

This new capacity range is the result of extensive testing and software enhancements. The YMC2 continues to offer these important benefits:

Market-leading efficiency, with an integrated part load value (IPLV) as low as 0.304 kW/ton at AHRI conditions and 10 percent better efficiency than conventional variable-speed centrifugal chillers

Superior sustainability supported by R-134a refrigerant, an efficient, safe and affordable refrigerant that will continue to be available for the life of all YORK chillers

Quietest chiller in its class, never louder than  73 dBA

Flexible operation, enabling the chiller to adapt to system condition changes of each unique facility and exceed cooling needs, even when other system components fall short

Maximized uptime, with 250,000 tons of chiller capacity installed, a fast re-start (can return to 100 percent capacity from a power loss in 3.5 minutes) and low maintenance (no gear or oil system)
