Sensitive electronics are best maintained in a stable environment of 72°F ±2°F (22.2°C ±1°C). 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 have more than just enough cooling capacity. It must have the precision to react quickly to a drastic change in heat load and prevent wide temperature fluctuations—something a large building system cannot do. 1.2 Humidity Control The electronic equipment must be protected from both internal condensation and static electricity discharges. Maintaining the correct humidity level in the room is just as important as maintaining proper temperature. When humidity is too high, condensation may form inside electronic equipment and damage it. If humidity is too low, static electricity could disrupt operation or even shut down the electronic system. An ordinary building system cannot normally control the environment within these boundaries. 1.3 Air Volume Computers and other sensitive electronics require greater air volumes than ordinary air conditioning can provide. Typical comfort systems are designed to provide between 300 and 400 CFM (cubic feet per minute), (500–700 CMH) per ton of cooling. Computer systems require between 500 and 600 CFM (850–1020 CMH) per ton. The high density heat load in a relatively small space requires more changes of air than a less dense “comfort” application. While a normal office space requires only two air changes per hour, a room filled with electronic equipment requires up to 30 changes per hour. Without proper air volume, hot spots and temperature fluctuations could develop within the room. Also, greater air volumes provide the higher sensible heat ratios required by electronic computer equipment. 1.4 Air Filtration A clean environment of properly filtered air is essential. Build-up of dust and fibers attracted by operating electronics can cause faults and impair the operation of electromechanical devices, such as switches and disk drives. In short, today’s electronics need the same precision environmental control that mainframe computers need. The difference is that instead of one large computer room there are several small, often crowded rooms, widely dispersed throughout a building, plant or campus. Conditions and requirements can vary widely. 1.5 Year Round Operation Comfort conditioning systems cannot be relied upon 24 hours per day 365 days per year. They are typically designed to operate 10 hours per day, from spring to autumn. Many “comfort” systems have no provision for winter operation. A precision environmental control system is designed for operation at temperatures down to -30°F (-34.4°C). 1.6 Agency Listed Standard 60 Hz units are CSA (NRTL-C) certified. NRTL-C meets both U.S. and Canadian government safety requirements, providing fast, problem-free inspection and building code approvals. The units are also MEA listed for New York City applications. 1 Precision Environmental Control for Industrial, Telecommunications, Medical and Data Processing Equipment 2.0 PRECISION ENVIRONMENTAL CONTROL FOR INDUSTRIAL, TELECOMMUNICATIONS, MEDICAL AND DATA PROCESSING EQUIPMENT Data processing power is moving from the specialized environment of the computer room to the office and the factory floor. At the same time, the applications are growing exponentially. From yesterday’s spreadsheets and word processors, micro- to mid-range computers control LANs and WANs, manage complex telecommunications systems, optimize manufacturing processes and facilitate sophisticated testing and laboratory functions. Computers and sensitive electronics tend to be grouped, often in specialized rooms. This makes operation and service easier, but it also creates the need for precision environmental control—the coordinated management of temperature, humidity and air filtration. 2.1 Liebert Challenger ITR Liebert Challenger ITR provides the precision and flexibility required by a broad range of applications. • Microprocessor-based controls (with a choice of monitoring systems based on your needs) allow you to select temperature and humidity ranges. • A-frame coil (oriented to airflow) provides a large cooling surface area, and more precise control of temperature and humidity. 2.2 Multiple Configurations to Fit a Variety of Spaces Though electronic equipment rooms share some common protection requirements, their application requirements can vary greatly. The room may or may not have a raised floor or an existing heat rejection loop. Budget and space requirements may limit the options a contractor has. 2.3 Efficiency in Economic Terms The Liebert Challenger ITR occupies 9.8 square feet (.91 square meters) of floor space. It can be located either between equipment racks or at the end of a row of racks. With room floor space valued at a premium per square foot, the small footprint of the Liebert Challenger ITR makes economic good sense. 2.4 GLYCOOL GLYCOOL is a patented Liebert process that can significantly reduce energy costs during periods of low outdoor temperatures. The GLYCOOL system is a normal glycol system with the addition of a second cooling coil, known as an Econ-O-Coil, in the air handling unit and a three-way valve. During colder months, the glycol solution returning from the outdoor drycooler is routed to the Econ-O-Coil and becomes the primary source of cooling for the room. At ambient temperatures below 35°F (1.6°C), the cooling capacity is sufficient to handle the total cooling needs of the room. Because the compressor is responsible for the majority of the power consumption of the air conditioning unit, a GLYCOOL system can substantially reduce energy costs. 2 Precision Environmental Control for Industrial, Telecommunications, Medical and Data Processing Equipment Figure 1 Unit configurations IMAGES ARE ILLUSTRATIVE ONLY Chilled Water, Self-Contained System Water-Cooled, Self-Contained System Plenum Available in two-way, three-way and four-way Free Discharge Grilles, Solid Plenum for ducting or low-profile, cold-aisle discharge plenum Condenser Water Pipes V-Frame Coil V-Frame Coil Scroll Compressor Condenser Air-Cooled, Self-Contained System With Matching Condensers Glycol-Cooled, Self-Contained System With Matching Drycooler and Pump Expansion Tank Air-Cooled Condenser Drycooler V-Frame Coil Scroll Compressor Glycol Pump Condenser V-Frame Coil Glycol Piping Scroll Compressor GLYCOOL-Cooled System V-Frame Coil Expansion Tank Drycooler Integrated GLYCOOL Coil Scroll Compressor Remote Condenser Water Source (not supplied by Liebert) Condenser Glycol Pump 3 Glycol Piping Precision Environmental Control for Industrial, Telecommunications, Medical and Data Processing Equipment Figure 2 Unit configurations, continued IMAGE IS ILLUSTRATIVE ONLY Split Systems Available Indoor Glycol-Cooled Condensing Unit Scroll Compressor Outdoor Prop-Fan Air-Cooled Condensing Unit Indoor Centrifugal Fan Air-Cooled Condensing Unit Remote Condenser Water Source (not supplied by Liebert) Expansion Tank Indoor Water-Cooled Condensing Unit V-Frame Coil Coaxial Condenser Scroll Compressor 4 Drycooler Glycol Pump Glycol Piping Local Monitoring Systems 3.0 LOCAL MONITORING SYSTEMS Two levels of microprocessor control systems are available providing precise control and monitoring of the critical space.

(.68 kg) insulation protect and quiet the system. The front door can be opened for service without shutting off the system. All components are accessible for service/maintenance through the front and rear of the unit. The Liebert Challenger ITR’s resistance to corrosion is enhanced by the black, powder-coat finish to all frame components. Exterior panels are similarly protected with durable powder-coating. 4.2 Electrical Panel The high voltage compartment contains the contactors, transformers and overloads and all other high-voltage components. Each high voltage component is protected by a separate overcurrent protective device. The entire high voltage panel is enclosed by a safety lock dead front panel. When the front door is opened by operating personnel, the high voltage components remain enclosed for operator safety. 4.3 Fan Section The Liebert Challenger ITR features a quiet, low speed fan assembly with double inlet blower, lifetime lubrication and self-aligning ball bearings. The motor and variable pitch drive are mounted on an adjustable base. The entire blower/ motor assembly is mounted on vibration isolators for smoother operation. The draw-through design of the fan section provides even air distribution across the coil, controlled air for bypass humidification, elimination of air bypass around the filters and low internal cabinet pressure drop. 4.4 Infrared Humidifier High-intensity quartz lamps over the stainless steel humidifier pan permit clean, particle-free vapor to be added to the air within 5 to 6 seconds of the electronic call from the microprocessor control. The quartz lamps provide radiant energy that evaporates water in a pure state, without solids. The Infrared Humidifier is equipped with an automatic water supply system that significantly reduces cleaning maintenance. This system has an adjustable water over-feed to prevent mineral precipitation. A drain valve is provided to easily empty the humidifier pan prior to inspection or servicing. A control valve regulates flow at water pressures between 5 and 150 psig (34.5 and 1034 kPa) and includes a Y-strainer. 4.5 Electric Reheat The two-stage 304 stainless steel reheat elements are a rigid, fin-tubular design that have extended operation life. The reheat has ample capacity to maintain room dry-bulb conditions during a system call for dehumidification. The two stages give an accurate, controlled response to the requirements of the computer room. The low watt density, electrically enclosed elements are surrounded by the tube and fins, reducing sheath temperatures and eliminating ionization. 4.6 Filters The standard pleated 2" (51mm) filter with an efficiency of 20% (based on ASHRAE 52.1) can be changed quickly and easily through the front of the unit. 7 Standard Features—All Systems 4.6.1 Condensate Pump The condensate pump, mounted in the bottom of most units, is used for unit drain water only. The condensate pump is complete with sump, motor and pump assembly and automatic control. The standard model has single float. A dual-float condensate pump, which includes connections to unit, common alarm, unit shutdown and one customer N/O contact is also available.

It is mounted in a vented, weatherproof enclosure. Optional Equipment—See page 16. 14 GLYCOOL Systems—Standard and Optional Features 9.0 GLYCOOL SYSTEMS—STANDARD AND OPTIONAL FEATURES 9.1 GLYCOOL—Self-Contained Models Only The Liebert GLYCOOL free-cooling system is integrated with a glycol-cooled Liebert Challenger ITR. At outdoor temperatures below 35°F (1.6°C), the Econ-O-Coil is capable of providing total system capacity. At outdoor temperatures between 35° and 65°F (1.6° and 18.3°C), the unique modulating valve permits partial cooling of the space by the Econ-O-Coil with the DX system picking up the rest of the load. Above 65°F (18.3°C) the unit functions as a glycol unit and all the cooling is accomplished by the DX system. When cooling is required, the three-way modulating valve and water regulating valve direct glycol (from the heat rejection loop) to the Econ-O-Coil located upstream of the evaporator coil, to the condenser, or to both. The GLYCOOL system contains all the standard features of a glycol-cooled system plus the following. 9.2 GLYCOOL System—Standard Features 9.2.1 Comparative Temperature Monitor A solid-state temperature monitor compares the room air temperature and entering glycol temperature. When air temperature is higher than glycol temperature, the monitor communicates to the microprocessor control that “free-cooling” is available. 9.2.2 Econ-O-Coil The Econ-O-Coil is strategically located in the return air stream of the environmental control system. This coil is designed for closed-loop applications using properly treated glycol solutions. Applications using a cooling tower loop or other open water system must specify a 70/30 Cu-Ni Econ-O-Coil for improved corrosion resistance. The air is first filtered before entering the coil and then is either precooled or totally cooled before entering the refrigeration coil. The glycol flow to the coil is controlled by a pre-piped modulating three-way valve. When supplied with a 45°F (7.2°C) glycol solution, the coil is sufficiently sized to offer the identical cooling capacity as is obtained during the refrigeration cycle of the compressor. 9.2.3 GLYCOOL Three-Way Control Valve The GLYCOOL Three-Way Control Valve opens full anytime the temperature of the glycol solution is below room temperature, to take full advantage of all possible free cooling. As the outdoor ambient drops, the three-way control valve modulates the flow to the Econ-O-Coil. It maintains constant temperature in the room and includes operating linkage and electronic motor. Unlike other valves of this nature, there is no over travel linkage or end switches to be adjusted. 9.2.4 Glycol-Regulating Valve A head pressure operated glycol regulating valve accurately controls the condensing temperature and system capacity for various entering glycol temperatures. The valve has three-way action. 15 GLYCOOL Systems—Standard and Optional Features 9.2.5 Drycooler The Liebert manufactured drycooler is constructed of aluminum with a copper tube aluminum fin coil. The low profile design features multiple direct drive propeller type fans, balanced to the heat rejection load. An integral, factory wired and tested control panel reduces installation time. Figure 7 Liebert Challenger ITR unit core Evaporator Coil Three-way GLYCOOL Control Valve Econ-O-Coil 9.3 Glycol and GLYCOOL-Cooled—Optional Equipment High Pressure For high pressure applications, the GLYCOOL system can be equipped with components rated at 300 psig (2069 kPa). 9.3.1 Dual Pump Package The dual pump package features two full size glycol pumps, each capable of providing sufficient flow for system operation. A flow switch will sense the loss of flow, should the lead pump fail, and automatically command the standby pump to start. The complete system includes dual pump housing, pumps, lead-lag switch and flow switch (for field installation). The dual pump package provides redundancy, protecting against costly downtime in the computer room.
