LIEBERT® CRV

SELF-CONTAINED ROW-BASED DATA CENTER COOLING, 11-50 KW

DESIGNED FOR COOLING ROWS OF RACKS IN SMALL AND MEDIUM DATA CENTERS

The Liebert CRV is a multi-option, precision data center cooling solution providing temperature and humidity control. It integrates within a row of data center racks, providing cooling close to the server heat source, for efficient and effective data center management. The system features Liebert iCOM controls and a variable capacity scroll compressor, resulting in high reliability and optimized system performance. The horizontal airflow is suitable for raised or non-raised floors.

Liebert CRV uses environmentally-friendly R410A refrigerant, and is available in different versions, depending on data center design requirements:

• 11 and 20 kW Direct Expansion (DX) air cooled version, available in the 300 mm frame
• 23 and 36 kW Direct Expansion (DX) air/water cooled version, available in the 600 mm frame
• 30 and 34 kW Chilled Water (CW) cooled systems, available in the 300 mm frame
• 40 and 50 kW Chilled Water (CW) cooled systems, available in the 600 mm frame
• 50 or 60 Hz models

Features:

• New space saving frame: 300 mm.
• Enlarged range available from 11 to 50 kW.
• Thermal management and humidity control
• Installs within the row of racks
• Low energy consumption
• Features variable speed EC plug fans and variable capacity scroll compressor
• Efficient operation with the iCOM control

Benefits:

Flexibility

• 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.

Availability

• 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 scroll compressor adapts to load and eliminates compressor cycling, greatly increasing compressor life.

Lowest Total Cost of Ownership

• Designed for higher return air temperature to maximize cooling capacity.
• Only front and back access required, resulting in minimized installation and service time.
• Variable capacity scroll compressor and variable speed EC fans operate efficiently to reduce energy consumption.

Ideally Suited For

• Small to medium-sized data centers cold/hot aisle configurations.
• Heat density up to 10 kW/rack without containment.
• Raised and non-raised floors.
• Rooms with a low ceiling where air cannot be ducted.
• Spot cooling in large data centers.
