The Liebert CRV, row-based cooling unit is optimized to ensure maximum cooling capacity in a minimal footprint. Targeted for small and medium data centers, as well as edge computing locations the unit provides cooling at the server rack level.

The Liebert CRV has been designed to deliver the highest eff iciency and availability, by removing heated air from the data center hot aisles, using it to return cooled air to the servers (cold aisle). The Liebert CRV is available in Direct Expansion, as well as Chilled Water versions and in two frame widths - 600 mm and a compact 300 mm. Providing full capacity and airflow modulation to match the servers' load, the unit is able to deliver energy savings via its compressor with capacity modulation, Electronic Expansion Valve and variable speed EC Fans. All this leads to very low operating costs with maximum availability. The

Designed to Optimize IT Performance

The Vertiv™ Liebert® CRV in-row cooling unit is ideal for the cooling of data center rows.

The Liebert CRV is a multi-option, precision air conditioner that delivers temperature and humidity control, as well as filtration and notification management, ensuring that data center temperatures are maintained at an optimum level.

The unit is designed to continuously monitor variations in heat loads and instantly deliver the most eff icient and eff ective cooling necessary.

Liebert CRV: Simple, Safe, Adaptable

The Liebert CRV is a plug-and-play unit with the capability of addressing the needs of both open and contained applications.

Cooling is provided at the server rack level rather than the room level. The Liebert CRV removes and filters hot air from the data center aisles, using it to return cooled air to the servers.

The integrated air diff users accurately direct the airflow towards the necessary direction of the heat load.

Furthermore, Liebert CRV is designed to comply with mission-critical requirements and ensure that servers are maintained at the correct temperature and humidity levels.

For low operational costs, the Liebert CRV provides the exact level of cooling required by servers, modulating the airflow and cooling capacity.

The unit is available in two versions to meet various installation demands:

y A stand-alone, direct expansion system with variable capacity up to 36 kW, available in both 300 mm and 600 mm versions, complete with roof or wall-mounted condenser y A chilled water system with up to 46 kW of capacity available in both 300 mm and 600 mm versions y Units ranging from 10 to 46 kW with chilled water and direct expansion versions y Industry's highest energy saving levels achieved -increase of up to 50% when the Liebert CRV is combined with Vertiv™ SmartAisle™ cold aisle containment y Best-in-class Thermal Management unit for row-based applications y On-site adjustment capability of air diff user distribution direction maximizes cooling results y Integrated Vertiv ICOM™ Control for management of capacity and airflow through EC Fans and variable capacity Compressor y Ideal for scalable IT infrastructure - increased cooling capacity, reduced noise levels and enhanced eff iciency when compared with similar chilled water and direct expansion configurations.

Features and Performance

The integrated compressors with cooling capacity modulation are designed to avoid peaks in absorbed power, thus reducing the stress placed on components. The Liebert CRV uses a dedicated control that also enables the compressor to operate when the external air temperature increases above standard limits.

Meeting Primary IT Requirements

The Liebert CRV's ability to modulate capacity allows for constant, accurate room temperature and humidity levels to be maintained.

The variable capacity capability of the Liebert CRV, contributes to increasing data center availability during both standard operations and in the event of load variations.

A reduction in its start/stop cycling function further contributes to increasing data center availability, as well as lengthening the life of critical components.

Extreme Flexibility for Open and Closed Architectures

Suitable For a Wide Range of Installations

The Liebert CRV addresses the cooling needs of both new and existing data center space, regardless of raised floor availability. It is ideally suited to data centers with up to 50 racks, irrespective of heat load.

Configuration Flexibility

The Liebert CRV can be configured to perform temperature as well as humidity control.

The Liebert CRV 300 mm and 600 mm width versions have been designed to specifically meet the requirements of data centers in need of optimizing space occupancy, as well as capital and running costs.

The Ideal Airflow

EC Fans and compressors with variable cooling capacity, managed through integrated Vertiv ICOM Control, achieve flexible capacity and airflow for the ideal operating conditions of IT equipment.

The Liebert CRV, designed using advanced, computer-aided dynamic fluid technology, delivers optimum air distribution across rack installations. The exceptional levels of air distribution have been proven as a result of wide-scale laboratory and field testing

Ensuring Availability Under All Working Conditions

Maintaining IT Infrastructure Availability

With integrated Vertiv™ ICOM™ Control, the Liebert® CRV is able to monitor variations in temperature and humidity, instantly adapting its performance to meet variations in load conditions.

This furthermore ensures increased availability and safety of protected IT equipment.

The Liebert CRV's constant temperature monitoring and control capabilities ensure the availability of servers in all working conditions.

Furthermore, its parallel load sharing functionality enables the management of N+1 configurations.

Customer Monitoring Interfaces

Monitoring and Control Through Existing Network Via your Web Browser

The Liebert® CRV system can be fitted with a Vertiv monitoring card allowing full advantage to be taken of the Ethernet network and remote monitoring from your computer desktop, network operations center or any network access simply utilizing a standard web browser. A standard web browser, via HTTP protocol or Network Management System software via SNMP protocol, can be used to access the unit information.

Monitoring Integration with Existing Building Management System

If required, by installing the optional monitoring card, the Liebert CRV can be monitored and controlled by an existing Building Management System.

The monitoring card provides Modbus, Bacnet and SNMP protocol support.
