Efficiency And Reliability In A Compact Package

1 liebert PeX with Digital ScrollEfficiency And Reliability In A Compact PackagePrecision Cooling for Business-Critical ContinuityWe Invented Precision CoolingEmerson Network Power knows precision cooling. After all, we invented it back in 1965! Over the years, our cooling systems have been proven as the world's standard for reliable operation. In fact, there are liebert precision cooling systems in the field that have been in constant use for over 30 years. Installed in thousands of critical data centers around the world, our latest precision cooling portfolio offers the highest Efficiency without compromising the 3 R's of Precision CoolingDespite the claims of different vendors promoting their own, specialized solutions, there is no silver bullet when it comes to precision cooling for every application.

2 There is only the most appropriate cooling solution for your infrastructure, which may or may not be appropriate for another. An understanding of each cooling design can help determine which cooling approach and solution can best meet your business goals and infrastructure CoolingWhile densities are climbing steadily, low density facilities remain the norm. Traditional room cooling uses precision computer room air conditioners (CRAC) and is the most appropriate solution for these low density environments. The low complexity, ease of deployment and precision humidity and filtration control of these systems has seen hundreds of thousands of units deployed in critical facilities across Asia, with more added every day.

3 Combined with a raised floor, CRACs deliver the best value for money and represents significant increased Efficiency over building or comfort room cooling meets the specific needs of a broad market there are times when an alternative approach is required by your business and CoolingIf energy Efficiency is top concern, row cooling can improve Efficiency over the standard room approach by more than 30 percent. It supports high density applications by the utilization of cold aisle containment. Row cooling with SmartAisle can further improve Efficiency and provide uniform and predictable temperature and humidity control to equipment with or without raised CoolingOne of the proven best practice approaches to dealing high density heat issues is by bringing cooling technologies closer to the source of heat.

4 Specialized precision cooling solutions for racks can support ultra-high-density applications, up to and above 30kW per rack. This dedicated cooling approach specifically cools a rack by providing the best direct air flow intake of the critical of the dimensions of the challenge be it lowering energy usage, reducing space, high densities, or any number of issues in the network and data center environment, trust on Emerson Network Power to match it up with a solution! We have the right cooling approach, technology and product to match your cooling needs. Our full range of cooling solutions are suitable to room, rack and now cooling approaches and can work together to create the most dynamic ultra efficient network Efficiency , Density and Availability withEmerson's Precision Cooling ProfolioRoomRackRowRoom + (Rack) + (Row)Rack0kW5kW10kW>30kWHeat DensityLiebert PEXL iebert CRVTMS mart AisleLiebert XDUltraEfficiencyCompressorsControlsCond enserFansEvaporatorFans200VA1,850 Watts2,360 Watts10,290 WattsCompressors Evaporator Fan Condenser Fans ControlsThe liebert PEX: More Than A Single Energy Efficient componentThe Efficiency of the liebert PEX is engineered into the product.
