Johnson Controls announced the launch of the York YVAM air-cooled magnetic-bearing centrifugal chiller operating with the low global warming potential (GWP) refrigerant, R-1234ze, for hyperscale and colocation data center cooling. To maximize uptime, the YVAM features Quick Start technology with integral uninterruptible power supply (UPS) backup, allowing the chiller to return to full load in as little as three minutes after power is restored. The chiller uses a variable-speed drive with active front-end to lower energy consumption and total harmonic distortion. The full-load sound is only 65 dBA at a distance of 10 meters. The machine’s lubrication-free design also eliminates the complexity of subsystems and reduces the costs of routine maintenance and system checks, the company says.
