Pumped Refrigerant Economization Eliminates California Data Center Water Usage

Higher Efficiency Without Using A Drop

The Liebert DSE freecooling system with pumped refrigerant economizer maximizes annual economization hours – and uses no water. With this system, data centers in California can:

  • Cut annual water usage by 4.3 million gallons for a typical 1MW data center
  • Reduce Time Dependent Value of energy by 8 percent to 10 percent
  • Eliminate water treatment costs and hazards
  • Eliminate the risk of outside air contamination
  • Maximize protection and efficiency through integrated advanced controls

Vertiv has published a full report showing the analysis of pumped refrigerant economization compared to water-side and air-side economization.
