JOHNSON CONTROLS LAUNCHES YORK^® YVAM MAGNETIC BEARING CHILLER

Johnson Controls announced the launch of the YORK^® YVAM air-cooled magnetic bearing centrifugal chiller operating with the ultra-low global warming potential (GWP) refrigerant, R-1234ze, for hyperscale and colocation data centre cooling.

The YORK^® YVAM chiller is one of the most efficient options for data center applications, because its magnetic-bearing technology allows the system to operate very efficiently at low lift conditions. This means the chiller doesn’t need free cooling coils to deliver performance comparable to air-cooled chillers with integral water-side economizers. Compared to traditional air-cooled screw chillers, the YVAM can improve efficiency by 49% in non-standard part load value (NPLV) in typical data centre conditions.

The YORK^® YVAM chiller uses a variable-speed drive with an active front-end to lower energy consumption and total harmonic distortion. This means the magnetic driveline is significantly quieter than traditional air-cooled chiller drivelines that use screw compressors. 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.

Data centres and other mission-critical facilities require non-stop cooling. A power failure could jeopardize operations and lead to costly downtime and performance penalties. To maximize uptime, the YORK^® 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.
