Freecooling Chiller Lowers PUE for Smaller Data Centers


by | Feb 11, 2014

Chiller Energy ManageEmerson Network Power is now offering its Liebert HPC-S chiller in the United States and Canada. The freecooling chiller enables small to medium size data centers to achieve better efficiency by creating an end-to-end chilled water system with integrated controls that lower the facility’s power usage effectiveness (PUE).

Emerson says the chiller is optimized to supply chilled water to indoor data center thermal management equipment and is more effective than air economizers. The unit’s freecooling mode allows it to cool water using less energy by reducing compressor usage when the external ambient temperatures are below the chilled water return temperature.

The chiller can operate in conditions below 0 degrees Fahrenheit (minus 18 degrees Celsius) as well as at higher outdoor ambient temperatures (as high as 78 degrees Fahrenheit/26 degrees Celsius).

The integrated Liebert iCOM control system adds intelligent control capabilities that allow the unit to adapt to changing environmental conditions and move to freecooling mode whenever conditions are appropriate. The system is networked to provide control of the chiller or group of chillers without the need for a separate building automation system.
