Liebert DSE with EconoPhase — Delivering Highest Efficiency DX Cooling with Pumped Refrigerant Economizer

April 20, 2021

In today’s data center, minimizing annual energy usage while maintaining reliability is increasingly important. Chilled water loops supported by water-side economizers have helped to decrease energy usage.

This product brief will provide an overview of the Liebert® DSE™ system and compare its unique design to comparable DX and chilled water cooling solutions. The Liebert DSE achieves industry-leading efficiency by offering a modular, end-to-end cooling infrastructure, complete with a high-efficiency indoor cooling unit, a pumped-refrigerant economizer, micro-channel outdoor condensers with variable-speed fan technology and a comprehensive management system built-in.

Key Takeaways

  • Hassle-free economization with Liebert EconoPhase™.
  • Precise control and enhanced efficiency through intelligent controls.
  • Variable-speed, direct-drive electronically commutated (EC) plug fans match airflow to server needs.
  • Variable-capacity digital scroll compressors match cooling to IT load.
  • Liebert MC™ condenser’s highly efficient micro-channel design integrated into the Liebert DSE system enables the system to achieve higher efficiency, reduced sound levels, reduced refrigerant charge and an overall decreased footprint.
