Liebert EconoPhase Pumped Refrigerant Economizer
The Liebert Econophase Pumped Refrigerant Economizer works with the Liebert DSE cooling unit and Liebert MC Outdoor Condenser to significantly improve data center efficiency – without bringing in outside air and without using water. The EconoPhase unit automatically switches to economizer operation during periods of lower outdoor temperature to reduce or eliminate compressor run time. The EconoPhase is an option for a Liebert DSE™ air-cooled system.
Note: Liebert is now Vertiv
