Liebert CRV, Self-Contained Row-Based Data Center Cooling Solution, 11-50 kW

A self-contained data center cooling unit that is ideally suited and designed for cooling server rack cabinets in small and medium data centers. Liebert CRV features Liebert iCOM controls and a digital scroll compressor, for high reliability and optimized data center management.


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
  • 38 and 57 kW Chilled Water (CW) cooled systems, available in the 300 mm frame
  • 46 and 58 kW Chilled Water (CW) cooled systems, available in the 600 mm frame
  • 50 or 60 Hz models
  • 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


  • 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.


  • 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.

Liebert APM ​is listed on the Energy Technology List (ETL).etllogo2.jpg

The ETL is a government list of energy saving products. Businesses that purchase products listed on the ETL can claim an​ Enhanced Capital Allowance (ECA) – a first year allowance that lets businesses set 100% of the cost of the equipment against taxable profits in a single tax year, providing accelerated tax relief.
