Emerson Network Power has introduced the Liebert® HPC-S Chiller in the United States and Canada, now making it available around the globe. The unique, freecooling chiller enables small to medium size data centers to achieve breakthrough efficiency by creating an end-to-end chilled water system with integrated controls that can help dramatically lower the facility’s power usage effectiveness (PUE) rating.
Optimized to supply chilled water to indoor data center thermal management equipment, the Liebert HPC-S Chiller features integrated freecooling technology that is more effective than air economizers and mitigates the operational limitations and concerns commonly associated with the technology. The unit’s freecooling mode allows it to cool water utilizing dramatically less energy by reducing compressor usage when the external ambient temperatures are below the chilled water return temperature.
The Liebert HPC-S Chiller has the additional advantage in data center applications of reliable operation below 0°F (minus 18°C). The freecooling chiller employs an optimized design with over-sized components that enable it to operate at higher outdoor ambient temperatures (as high as 78°F / 26°C), thereby maximizing time available for economizing operation.
“At a time when data centers are becoming more complex, companies are looking for more efficient real-time environmental control that helps improve operational efficiency and reduce operational expenditures,” said John Schneider, vice president and general manager, thermal management, Emerson Network Power. “Equipped with the leading technology —such as the Liebert iCOM™ control system, EC condenser fans, and Copeland Scroll™ compressors — the Liebert HPC-S Chiller delivers up to 40% annual energy savings in data center applications over traditional products.”
The integrated Liebert iCOM control system adds intelligent control capabilities that allow the unit to adapt quickly to changing environmental conditions and instantaneously move to free cooling mode whenever conditions are appropriate. The system is easily networked to provide efficient control of the chiller or group of chillers without the need for a separate building automation system.
Additionally, the Liebert HPC-S is compatible with the Liebert CRV row-based chilled water-based cooling unit. Coupling the Liebert CRV Optimized Aisle Controlfeature with cold aisle containment and the Liebert HPC-S chiller enables an end-to-end chilled water solution that offers increased energy efficiency and more control for the end user. The configuration is capable of achieving a mechanical PUE of 1.20, delivering maximum availability by ensuring that each watt of power is used to cool the servers.
