Emerson Network Power Announces Water and Energy-Saving Liebert® DSE with Liebert EconoPhase Economizer Approved for California Data Centers
Designed to save millions of gallons of water and increase energy efficiency by up to 50 percent
Columbus, Ohio [September 16, 2015] – Emerson Network Power, a business of Emerson, (NYSE: EMR) and the world’s leading provider of critical infrastructure for information and communications technology systems, today announced that the California Energy Commission (CEC) has approved the use in California data centers of the Liebert® DSE thermal management system with the Liebert EconoPhase Pumped Refrigerant Economizer. The Liebert DSE system represents a break-through technology that uses no water and saves up to 50 percent of thermal energy, through its patented design and advanced Liebert iCOM™ controls.
“The Liebert DSE system is a great environmental steward. When used in a typical mid-sized data center of one megawatt load, the Liebert DSE is significantly more efficient than current cooling systems, and eliminate the use of around four million gallons of water each year. If deployed broadly in California data centers, the Liebert DSE with EconoPhase could save hundreds of million gallons of water every year,” said John Peter Valiulis, vice president North America marketing, thermal management, Emerson Network Power.
The CEC has approved theLiebert DSE system with Liebert EconoPhase as a prescriptive economization option, as part of Title 24 of the the CEC’s 2103 Building Energy Efficiency Standards For Residential and Non Residential Buildings, meeting the code’s requirements for energy efficiency and its prescriptive requirements for economizers.
The Liebert DSE system eliminates the need for any water in the heat rejection process and associated chemical water treatment, and it eliminates the risk of exposure to harmful waterbound bacteria. In addition, the Emerson modeling for the CEC compliance program demonstrated an 8 to 10 percent reduction in the data center Time Dependent Valuation measure, compared to the water economizer prescriptive option. The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers. In actual usage, the entire Liebert DSE system has demonstrated thermal system energy savings of up to 50 percent over older legacy systems.
