Reduce costs and increase economization hours with the highly efficient Liebert DSE Packaged Free-Cooling Solution. The Liebert DSE is the world’s most widely deployed pumped refrigerant economization system for data centers, with over 6,000 installations.

Features

High Energy Efficiency
  • Refrigerant economizer pumps take over for compressors during cooler hours, using one-tenth the power
  • Operational PUE under 1.2Highly efficient at low load or part load conditions
  • Advanced Liebert iCOM controls optimize individual component operations for higher efficiency
  • Even in full compressor mode, the unit is more efficient than heat wheels and other DX systems Built-in optimized control and monitoring
  • Advanced algorithms and protection routines keep units operating within safe thresholds
  • Automated and smooth economizer transitions
  • Multi-unit teamwork mode eliminates unit fighting and increases efficiency
  • Lead/lag settings allow easy standby unit startup
  • Onboard protocols simplify integration with building management systems Easy Servicing, Reduced Maintenance
  • EconoPhase and condenser components can be serviced from the end of the unit, and evaporator components can be accessed via side entry, allowing units to be placed closely together
  • Liebert economization pumps are virtually maintenance free
  • No dampers to service or outside air filters to replace
  • Only standard DX servicing required; no special maintenance needed  Reduced Air Leakage
  • Less than 0.5% air leakage, reducing need for extra capacity for makeup air
  • No volumetric displacement  Easy Fit Up to Building
  • Perimeter configuration  

Benefits

  • Highly Flexible. The system is available as a single unit for perimeter locations, integrating all key cooling components for fast deployment. Its pumped refrigerant platform separates outside air from data center air to eliminate cross-contamination or humidity transfer.
  • Finely Tuned Controls. The system’s industry-leading Liebert iCOM controls capture every available economization hour, with smooth, automated transitions. Advanced protection routines keep the system operating safely within thresholds. Automatic, multi-unit teamwork modes harmonize thermal management across the data center. Optimization routines reduce energy usage. Onboard protocols make integration with building management systems easy.
  • Minimal Air Leakage. The solution operates at less than 0.5% leakage at normal operating pressures with no volumetric displacement commonly associated with heat wheels.
  • Easy Servicing. The Liebert DSE has fewer moving parts than other economizer systems, reducing the likelihood of component downtime and maintenance. EconoPhase and condenser components can be serviced from the end of the unit, and evaporator components can be serviced via side entry, allowing units to be placed closely together.
