Emerson Network Power has introduced three new models of the Liebert DSE, room-based data centre cooling systems. The 80kW, 85kW and 150kW units will join the current 125kW unit, will be available across North America.
The Liebert DSE features the EconoPhase pumped refrigerant economiser that cools without the cost of water consumption or air contamination thus lowering operational costs.
The unit also features compressors to make the most of part-load efficiency, electronic expansion valves to support lower condensing temperatures, and variable speed electrically commutated plug fans that adjust the unit airflow to demand based on usage.
“The Liebert DSE represents the state-of-the-art in data centre room cooling and demonstrates that major increases in cooling efficiency can be achieved without compromising data centre reliability and performance,” said Steve Madara, Vice President, global cooling, Emerson Network Power. “These new models give data centre designers and managers more options to configure data centre cooling that is scalable, reliable and economical.”
