Overview

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 heat management. The system features Liebert iCOM™ controls and a digital 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. For maximum application flexibility the row-based cooling system is available in multiple capacities and configurations:

  • 600mm wide: 20kW or 35kW air or water/glycol based,
    or 40kW chilled water-based cooling units.
  • 300mm wide: 19.6kW air cooled, or 30kW chilled water-based cooling units
Features
  • Precision cooling and humidity control
  • Installs within the row of racks
  • Features variable speed EC plug fans and variable capacity digital scroll compressor
  • Operates efficiently with Liebert iCOM controls
Benefits

Flexibility

  • Available in nominal capacities from 19.6kW to 40kW.
  • Automatically balances the airflow and cooling capacity independently based on the needs of the IT equipment.
  • Horizontal airflow cooling design is suitable for non-raised or raised floors.
  • Air, water, glycol and chilled water systems available.
  • Adjustable supply air baffles maximize cooling to rack equipment by avoiding the need to provide extra air that is lost to the room.
  • Caster mounted for easy placement.
  • Up to 10 racks with 20 sensors per cooling unit may be monitored to improve system performance and report rack temperatures.
  • Compatible with both Emerson Network Power SmartAisle™ infrastructure, and Aisle Containment system.

Availability

  • Wellness monitor alerts users in advance of potential issues.
  • Self-adapts to changing conditions to provide 24/7 precision environmental control: cooling, humidity control and air filtration.
  • Built for both ease of installation and speed of maintenance. All components are easily accessible from the front and rear of unit, eliminating side access.

Lowest Total Cost of Ownership

  • Designed for higher return air temperature to maximize cooling capacity.
  • Easy to install and maintain – only front and back access required.
  • Digital scroll compressor and variable speed EC fans operate efficiently and provide a long service life.

Ideally Suited For

  • Small to medium-sized data centers.
  • Rows of racks in hot aisle / cold aisle configuration.
  • Supporting capacity of existing raised floor cooling units.
  • Rooms with a low ceiling where air cannot be ducted.
  • Rack equipment with high heat density, or a mix of densities.
  • Spot cooling in large data centers.
