1 Precision Cooling For Business-Critical ContinuityLiebert DS Designed To A Higher Standard Of Performance And ReliabilityDATA CENTER SOLUTIONSFor More Information:(866) Understands The Need For Precision And Why This Is So Important To YouFor sensitive electronics, environmental control is more than simple cooling. Comfort air conditioning systems are designedto cool people and office space. They simply cannot provide the kind of environment required by high performance computer orcommunication equipment. Why You Can t Take Chances When Cooling Your Critical SpaceStandard building cooling systems are designed to keeppeople comfortable 8-12 hours each day from spring toautumn with no provision for winter operation. A precisioncooling system is designed to operate over a wide range ofambient temperatures from as low as -30 F ( C) up to120 F ( C).Sensitive electronics must be maintained in a stableenvironment of 68 F to 77 F (20 C to 25 C) with a relativehumidity of 40% to 55%.

2 Computers and communicationsequipment generate six to ten times the heat density of normal office space, the air conditioning system must have more than just enough cooling must have the precision to react quickly to a drastic changein heat load and prevent wide temperaturefluctuations something a large building HVAC system cannot do. A Tradition Of Reliability You Can Count OnLiebert Mission Critical Cooling equipment is the standardby which all others are judged. The number of units that arein the field far exceeds the combined number of all otherbrands. Nine out of ten Fortune 500 Companies use Liebertcooling systems. Liebert Mission-Critical Cooling Systems are used in themost demanding, critical applications in the world.

5 Modular frame construction allows even more flexibilityin meeting specific needs for installation frame can befield-separated into three sections. Built-in humidity control and reheat function. Liebert iCOM control system brings high-levelsupervision to multiple units allowing them to worktogether as a single system to optimize roomperformance. Available with R-407C environmentally friendlyrefrigerant or R-22 standard Total Cost Of Ownership: Energy efficiency options and configurations can savemoney and even pay back part of your investment overthe life of the product. Built for serviceability, with many components such asthe Paradenser cleanable condenser designed to bemaintained rather than replaced. Specifically designed for the demanding requirements ofyear-round operation, the Liebert DS is actually lessexpensive to operate over its life cycle compared to bothcomfort cooling equipment and competitive precision airconditioning Liebert DS Is Designed And Built Like No Other4 The Liebert DS is designed to fit room applications requiringhigh level precision control of the room environment,including temperature, humidity, filtration and airflow.

6 Designed For Energy EfficiencyLiebert is dedicated to providing maximum energyefficiency in its precision cooling systems withoutcompromising the accuracy and reliability demanded bysensitive electronics. All enhancements to energy efficiencyare designed to reduce operating time of key componentsand increase the Mean Time Between Failure. This isaccomplished by taking advantage of alternate sources of cooling by minimizing compressor operation when heat loads in the conditioned space are lower. Energysavings is also gained through the use of high efficiencycomponents such as advanced digital scroll and 4-stepsemi-hermetic compressors. Quality, Rugged ConstructionThe durable design of the Liebert DS provides a stable, virtually vibrationless platform for compressor and fan operation:Autophoretic frame coating protects frame againstcorrosion for years of reliable frame 14 gauge steel provides ruggedconstruction, proven to withstand shipping and handlingthrough ISTA (International Safe Transit Association)certified ship powder coated exterior panels look good and stay that and tab sheet metal for consistent, double-skin panels eliminate insulation in theair stream.

7 This allows for easy panel floorstands Adjustable standard and seismic-rated floorstands allow for installation and connection ofthe system prior to the installation of the raised in heights from 6 to 36 , a field installed turningvane may be specified. Precise Temperature And Humidity ControlThe environmental control system must be able to senseand react to temperature and humidity fluctuations fartoo small for building HVAC systems to control. TheLiebert DS is capable of control to within 1 F ( C) and 1% RH. By analyzing the rate of change in temperatureor the moisture content in the environment, the controlsystem anticipates what is going to happen in the room,not simply responding to what has For Precision, Efficiency And Strength 5 Front Access And ServiceabilitySave Valuable Floor SpaceTotal front access provides space andserviceability benefits not found onprevious models or competitive units. The Liebert DS can be placed adjacent to or in back of other equipment oragainst a wall or key components visible and accessible from the front of the unit for easy maintenance and removable from front isolated from air stream for FrameConstructionThe unit s modular frameconstruction allows even moreflexibility in meeting specific needsfor installation, energy efficiency andother special can be field-separated intothree sections enables unit to fitinto small elevators or through othertight DS Units Can Be Configured ForOptimum Cooling Of Any Type Of SpaceDownflowconfigurations are designed for use in raisedfloor applications such as data centers and other facilitieshousing sensitive electronic equipment.
