    • LIEBERT UNDERSTANDS THE NEED FOR PRECISION AND RELIABILITY… AND WHY THIS IS SO IMPORTANT TO YOU For sensitive electronics, environmental control is more than We Have The Right Solution For Your simple cooling. “Comfort” air conditioning systems are Specific Application Liebert has identified a number of distinct zones or areas of designed to cool people and office space. They simply cannot2 application, found within many business-critical applications, provide the kind of environment required by high which have a requirement for mission-critical cooling performance computer or communication equipment. technologies. Each zone has similarities but with different needs for infrastructure protection — all of which can be met by Liebert solutions. Why You Can’t Take Chances Specific zones where the Liebert DS can be used include: When Cooling Your Critical Space I Data Centers I Telecom/CATV Standard building cooling systems are designed to keep I Computer Rooms I Labs And Testing people comfortable 8-12 hours each day, five days a week I Network Operations Centers I Production Facilities and only during the warmest months. Sensitive electronics must be maintained in a stable environment of 68°F to 77°F (20°C to 25°C) with a relative humidity of 40% to 55%. Because computers and communications equipment generate large quantities of heat in small areas, six to 10 times the heat density of normal office space, the air conditioning system must A Tradition Of Reliability You Can Count On have more than just enough cooling capacity. It must have Liebert Mission Critical Cooling equipment is the standard the precision to react quickly to a drastic change in by which all others are judged. The number of units that are in heat load and prevent wide temperature fluctuations the field far exceeds the combined number of all other brands. — something a large building HVAC system cannot do. 9 out of 10 Fortune 500 Companies use Liebert cooling systems. Liebert Mission-Critical Cooling Systems are used in the most demanding, critical applications in the world.

    • THE LIEBERT DS IS DESIGNED AND BUILT LIKE NO OTHER 3 Designed For Reliability Because electronic system availability is required 24 hours a day, 365 days a year, the environmental control system must meet the same demands. The Liebert DS is designed with the highest quality components selected for their proven reliability. Microprocessor technology adds automatic sequencing of components to even wear and extend service life. An alarm system and self-diagnostics provide rapid troubleshooting and can prevent a problem before it affects the electronic equipment room environment. Year-Round Operation Under Many Climate Conditions Comfort conditioning systems cannotEngineering Excellence Goes be relied upon 24 hours per day 365 daysInto Every Liebert DS per year. They are typically designed to The Liebert DS is based on the proven design and operate 10 hours per day, from spring to autumn. Many comfort systems have notechnology of Liebert Deluxe Systems used in thousands provision for winter operation. A precisionof critical data centers around the world since 1965. environmental control system is designed to operate over a wide range of ambient Full scale analysis and evaluation of the Liebert DS during all temperatures from as low as –30°Fphases of development and production is your assurance of (-34.4°C) up to 120°F (48.9°C).the most advanced performance and highest quality. Units arethoroughly tested under a wide variety of temperature and Precise Temperature Andhumidity conditions. Humidity Control The environmental control system must be able to sense and react to temperature and humidity fluctuations far too small for building HVAC systems to control. The Liebert DS is capable of responding to changes as small as ±1°F (°C) and ±1% RH. By analyzing the rate of change in temperature or the moisture content in the environment, the control system anticipates what is going to happen in the room, not simply respond to what has happened.
    • ENGINEERED FOR STRENGTH AND APPLICATION FLEXIBILITY The Liebert DS is designed to fit room applications requiring Downflow Configurations4 Designed for use in raised floor applications, such as data high level precision control of room environment, including centers, the Liebert DS downflow configuration combines temperature, humidity, filtration and airflow. top air return with bottom air supply to circulate air underneath the floor.

    • AIR DELIVERY SYSTEM DESIGNED FOR OPTIMIZED AIR DISTRIBUTION AND LONG SERVICE LIFE Centrifugal blowers enable performance over High efficiency 5-YEAR DRIVE COMPONENTS a wide range of air motor meets (bearings, belts, shaft, pulleys) volume and static NEMA Premium pressure ranges. motor standard. Computers and other sensitive electronics6 require greater air volumes than comfort air conditioning can provide. The high density heat load in the relatively small space of a data center requires more air changes to remove heat properly. A key to the outstanding performance of the Liebert DS is its optimized air delivery design. It combines high efficiency and effective air handling to deliver reliable, constant cooling under the most demanding conditions.

    • DEPENDABLE, EFFECTIVE COOLING SYSTEM At the heart of the Liebert DS are its cooling system components, each designed to provide maximum reliability.8 Draw through design pulls air evenly through the cooling coil, reheat and humidification systems. A-frame coil design maximizes coil area reduces air velocity, lowers chance of water blowing off coil, results in far less turbulence with superior efficiencies in heat transfer.

Switchover between the two cooling modes is performed automatically by a microprocessor control and temperature sensor. In addition to energy efficiency, this option can provide increased redundancy and flexibility to the environmental control system.
    • CONTROLLING THE CRITICAL ENVIRONMENT A key to the ability of a quality Mission Critical Cooling system to control conditions within the critical space is its high “sensible heat ratio.” Standard Infrared Humidifier Instant humidification on when needed, off when not needed.10 Unlike people, computers generate dry or “sensible” heat, but not humidity. With a large percentage of their total capacity devoted to the removal of moisture, comfort systems can lower room humidity far below acceptable standards for electronic equipment — and they have no provisions for adding moisture. To correct this situation, precision air conditioning systems typically have a high ratio of sensible-to-total cooling capacity to remove heat from the air. This capability is provided through the use of integrated humidification systems to provide the necessary level of moisture control, higher air supply capacity and larger coil size. Humidifier make-up Pure water vapor Does not depend on water quality. High valve controls flow provides most intensity quartz lamps shine on water of water to the effective creating instantaneous moisture using humidifier pan. humidification. almost any water quality. Humidity Control Maintaining the correct humidity level in the room is just as important as maintaining proper temperature. Inadequate humidity control can cause static electricity if it’s too dry — or condensation that can corrode circuitry if the air is too moist. Comfort cooling systems can lower room humidity far below acceptable standards for electronic equipment — and they usually have no Optional Steam Generating provisions for adding moisture. The Liebert DS utilizes an integrated Canister Humidifier humidification system to provide the necessary level of moisture control.

The I Utilizes a drain and refill cycle— precision control of the Liebert DS saves energy by tightly regulating to maintain a current setpoint. compressor operation and avoiding over-dehumidification that causes the humidifier to come on when not needed.
    • Minimum Efficiency Reporting Value (MERV), adopted by ASHRAE in its 52.2 standard. 11 Filtration System The Liebert DS features integral air filtration to protect against airborne contaminants within the critical environment. Without proper air filtration, even small amounts of dust and other particles can damage storage media and charged electronic components. • High efficiency air-filtration — removes damaging particles from air. • Standard filter — 4” deep, Merv 8.
