1.1System Descriptions

Challenger 3000™ Liebert environmental control systems are available in several configurations. Each configuration can operate with either Advanced Microprocessor Controls (A), or Advanced Microprocessor Controls with Graphics (G). A brief description of each, including operational differ- ences, are listed below. Check model numbers to see what is supplied with your unit.

1.1.1Compressorized Systems

NOTE

Compressorized systems may be a self-contained system – with the compressor in the Challenger 3000 unit, or a split system – with the compressor in the separate condensing unit.

These systems may be air, water, or glycol cooled, depending on the heat rejection method selected. Cooling—One stage standard; two stages of mechanical refrigeration with optional split coil.

Heating—Two stages of electric reheat standard; SCR controlled electric reheat, hot water reheat, hot gas reheat on water and glycol cooled systems optional.

Humidification—Infrared standard; steam generating optional. Dehumidification—Hot gas bypass locked out standard; part coil operation optional

1.1.2GLYCOOL™ (Chilled Glycol Cooling) Systems

GLYCOOL™ systems have all of the features of a compressorized water or glycol system, plus a sec- ond cooling coil that is connected into the water circuit. When fluid temperature is sufficiently low (below room temperature), cooling is provided by circulating the fluid through the second cooling coil (flow is controlled by a motorized valve.) This is then the primary cooling source and it greatly reduces the compressor operation.

Cooling—Modulated cooling valve opens proportionally to match room needs (primary), one or two stages of mechanical refrigeration (secondary)

Heating—Two stages of electric reheat standard Humidification—Infrared standard; steam generating optional Dehumidification—Hot gas bypass locked out standard

1.1.3Chilled Water Systems

These systems utilize a central chiller and control cooling by modulating a control valve in the chilled water line.

Cooling—Proportional in response to room needs Heating—Two stages of electric reheat standard Humidification—Infrared standard; steam generating optional

Dehumidification—Chilled water valve opens proportionally in response to room needs

3000 specifications

The Liebert 3000 is a cutting-edge power protection solution designed to provide reliable and efficient backup power for critical applications. This uninterruptible power supply (UPS) system is engineered to safeguard sensitive electronic equipment from power disturbances, ensuring uninterrupted operations in data centers, telecommunications, and industrial environments.

One of the standout features of the Liebert 3000 is its high-efficiency design. With an efficiency rating of up to 94%, the system minimizes energy loss, resulting in lower operational costs and a reduced carbon footprint. This is particularly important in today's environmentally conscious climate, as organizations strive to meet sustainability goals while maintaining top-tier performance.

The Liebert 3000 employs advanced technologies to enhance its functionality. It incorporates online double-conversion technology, which provides a continuous supply of clean and regulated power.
