Liebert® CRV Row-Based Cooling
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 e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 Liebert CRV is a omprehensive row-based solution that includes all of the main functions fundamental to cooling units, such as cooling, humidification, dehumidification, re-heating, air filtration, condensation management, temperature and humidity control, alarm functions and data communications.
Furthermore, the unit enhances its performances and energy eiciency through the Vertiv™ ICOM™ Control, capable of optimizing unit operations by leveraging on its intelligent management of system components. All components are easily accessible from the front and the rear of the unit, granting simplified service intervention.
The unit also allows ease of installation, through simplified cable and pipes routing from top and bottom of the unit.

Designed to Optimize IT Performance
The Liebert® CRV, row cooling unit Thermal Management unit is ideal for the cooling of data center rack 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 eicient and e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 di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
y A chilled water system with up to 60
system with variable capacity up to 36kW, available in both 300 mm and 600 mm versions, complete with roof or wall-mounted condenser
kW of capacity available in both 300 mm and 600 mm versions.
Features and Performance
y Units ranging from 10 to 60
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 row­based applications
y On-site adjustment capability
of air di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 eiciency when compared with similar chilled water and direct expansion configurations.

Vertiv™ Liebert® CRV from 10 to 60 kW
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.
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
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.
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.
