Precision cooling system
Emerson Network Power's Liebert DSE is a room-based precision cooling system designed specifically for medium to large data centers.
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.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
