Emerson Network Power’s Liebert DSE is a room-based precision cooling system designed specifically for medium to large data centers. The Liebert DSE provides 125 kW of net sensible cooling, offering energy savings at full load and partial load conditions. The Liebert DSE incorporates several technologies that improve its overall energy efficiency. They include Copeland tandem digital scroll compressors that optimize part-load energy savings and electronic expansion valves that enable operation at lower condensing temperatures. This reduces compressor power and improves efficiency during lower ambient conditions and partial loads. Variable speed, electronically commutated plug fans automatically adjust unit airflows to match the IT server demands, improving air efficiency and reducing total system power consumption at full speed. Staged evaporator coils provide greater efficiency by enhancing the ability to enable partial free cooling. The Liebert DSE also features the Liebert iCOM control system, which provides advanced diagnostic and maintenance support.
