Liebert Challenger ITR (In-The-Row) Precision Cooling The Liebert Challenger ITR is a horizontal airflow precision cooling unit that fits within a row of equipment racks. It draws hot air in through the extended rear door and supplies chilled conditioned air through a low profile, cold aisle discharge plenum. This CRAC unit is available in nominal 23 kW or 33 kW capacity, 60 Hz. 50 Hz models also available. The Challenger ITR can be placed between cabinets in the row, or at the end of a row, on raised or non-raised floors. This flexibility, along with the multiple cooling configurations, allows the system to easily conform to your application. This precision cooling system supplies the features demanded by electronic equipment in rack applications: Monitoring- Monitoring and control of system operation are available from the unit-mounted control panel. Remote network-based monitoring and control is available through the optional Liebert IntelliSlot Web/485 Card with Adapter. Compatible with the Liebert family of monitoring products. Temperature Control- Controls the environment to the requirements of sensitive electronics to prevent damage caused by temperature extremes. Humidity Control- Rapid response, precise Infrared Humidifier or Steam Generating Humidifier available to control humidity to the levels required by sensitive electronics. Space Considerations- Accommodates low ceilings and overhead cabling. Same depth as standard racks.
Minimal service clearance requirements. Energy efficiency- Scroll compressor and microprocessor control system work together to operate at maximum efficiency. GLYCOOL option offers reduced compressor operation for colder climates. Sound- Operates at 85dBA - the quietest operation of any row-based cooling system. Service/Maintenance- Generous service allowances are built into the cabinet design, speeding service and maintenance. Filter maintenance can be performed by your onsite personnel. Cooling Method- Available in air, water, glycol, GLYCOOL, and chilled water cooling configurations - install the system that meets your needs. 24x7x365 Operation Durable components designed for 24/7 operation.
Convenient filter access through the hinged rear door

Liebert Challenger ITR
Precision Cooling System
The Liebert Challenger ITR offers many benefits: Flexibility: - Designed for flexibility in installation, configuration, operation and maintenance.
- Low profile, cold aisle discharge plenum is easily reconfigured to change supply air direction, and is designed to accommodate overhead IT cabling.
- Adjustable cooling capacity allows you to match the heat load to reduce compressor cycling.
- Split system configurations remove compressor noise from the data center for quieter operation.
- Offers two levels of microprocessor control systems.
- Fits aesthetically in the row - same depth as common server racks (1100mm - 43").
- Offers a full range of configurations - self-contained or split systems; air, water, glycol, GLYCOOL and chilled water cooling.
- Customizable, with two humidifier and four reheat options.
- Provides enhanced temperature control with optional SCR-controlled reheat.
Higher Availability:- Based on a proven cooling platform - Liebert Challenger 3000.
- Compatible with Liebert remote monitoring and
control products. - Requires only front and rear door access, minimizing
the footprint requirements while providing ample room for service. - Features reliable refrigeration components, such as a scroll compressor and V-Frame evaporator coil, all factory pre-piped, wired, and tested in a rugged, easy-access tubular-steel frame.
Low Total Cost Of Ownership: - Utilizes energy efficient scroll compressor.
- Minimizes short cycling and other wasteful operating patterns with fast response microprocessor controls.
- Energy efficient GLYCOOL configuration utilizes low outdoor temperatures to reduce compressor operation.
Ideally Suited For: - Data Centers
- Network Closets
- Raised or non-raised floors
