Precision Cooling in less than 7.5 Square Feet of Space The Liebert Challenger 3000 precision air conditioning system provides complete environmental control, including precise temperature, humidity and air filtration. Designed to fit in the crowded confines of an equipment room or laboratory, it offers an extremely compact footprint for facilities where space is at a premium. All of the critical components are accessible from the front, so the unit can be installed in a corner or flush against other equipment. The Liebert Challenger 3000 is available in 10.5 and 17.5 kW (3 and 5 tons) capacities, 60 Hz and 50 Hz models. The Challenger 3000 can be configured to match the needs of a wide variety of site requirements. - Direct Expansion: includes Air cooled, Water cooled, Glycol cooled, and GLYCOOL (see image below)
- Chilled Water: require connection to a chilled water source
- Self-Contained: package all refrigeration components within the cabinet to minimize installation time. (see image below)
- Split System: split the refrigeration components between the room unit and a condensing unit.

Precise Temperature Control The Infrared Humidifier has been a feature on Liebert environmental control systems for over 25 years. Its rapid response and cleanliness has made it an industry standard in applications that demand precise, particle-free humidity control. An Autoflush System reduces the buildup of mineral solids and reduces maintenance time. If your application
calls for a Steam-Generating Humidifier, Liebert can respond. The disposable canister makes maintenance quick and easy. 
A look inside the Liebert Challenger 3000
Local Monitoring And Control Microprocessor-based controls help the Liebert Challenger achieve precise temperature and humidity for your sensitive electronics. Two levels of Liebert microprocessor control systems are available, providing precise control and monitoring of the critical space. The Liebert Advanced Microprocessor is standard, while the Liebert Advanced Microprocessor with Graphics is optional. These controls provide unit control, monitoring, diagnostics, alarms and event logging. Application Example- Computer Room On a square foot basis, computer rooms generate up to five times the heat of normal office space. The Liebert Challenger is designed to handle this load efficiently with a high sensible heat ratio and an air delivery system capable of 1800-3000 C.F.M. Because most computer rooms use a raised floor for air circulation and cable management, the Liebert Challenger can be specified with underfloor air discharge. This reduces the turbulence created by competing warm and cold air streams. Is the Liebert Challenger 3000 the best CRAC solution for your cooling needs?
