LIEBERT PR22582V2-134416.eps

Liebert Challenger3000 provides complete control of temperature, humidity and air

filtration. The unit offers an extremely compact footprint, ideal for facilities where

space is at a premium. All critical components are front-accessible, so the unit may

be corner-installed or installed flush against other equipment. Liebert

Challenger3000 is available in 10.5 and 17.5 kW (3 and 5 tons) capacities, 60 Hz

and 50 Hz models. Air cooled, water cooled, glycol cooled, GLYCOOL and chilled water

configurations. Upflow and downflow models available.

FEATURES

• Offers two levels of microprocessor control systems

• Provides enhanced temperature control with optional SCR-controlled reheat

• Reduces noise levels within the room unit, when installed as a split system with

remotely located compressor and condenser

• Features reliable refrigeration components, such as a scroll compressor and

A-Frame Evaporator coil, all factory pre-piped, wired, and tested in a rugged,

easy-access tubular-steel frame

• Utilizes scroll compressor for energy efficiency

• Minimizes short cycling and other wasteful operating patterns with fast

response microprocessor controls

LIEBERT PR29209V2-216043.eps

The Liebert CRV installs within a row of data center equipment racks, providing

precision cooling close to the server heat source for the most efficient and effective

operation. The system features Liebert iCOM controls and a digital scroll compressor,

resulting in high reliability and optimized system performance. Liebert CRV is

available in 20 or 35 kW air cooled and water/glycol cooled systems, and 40 kW

chilled water cooled systems. 60 Hz models. Horizontal airflow, suitable for raised or

non-raised floors.

FEATURES

• Horizontal airflow cooling design is suitable for non-raised or raised floors.

• Air, water, glycol and chilled water systems available

• Adjustable airflow baffles maximize cooling to rack equipment, allowing the

system to be positioned within the row or at the end of the row

• Caster mounted for easy placement

• Multiple units communicate with each other to improve system performance

and reduce energy consumption

• Up to 10 racks per cooling unit may be monitored to improve system

performance and report rack temperatures

• The iCOM large graphic display allows easy navigation and clear data display.

• Can be used with SmartAisle containment system

• Self-adapts to changing conditions to provide 24/7 precision environmental

control: cooling, humidity control and air filtration

• Liebert iCOM control provides alerts for preventive maintenance before

issues occur

• Variable capacity Digital Scroll compressor adapts to load and eliminates

compressor cycling, greatly increasing compressor life

• Designed for higher return air temperature to maximize cooling capacity

• Only front and back access required, resulting in minimized installation and

service time

• Digital scroll compressor and variable speed EC fans operate efficiently to

reduce energy consumption
