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

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.

Optimizing Total Cost of Ownership

Delivering Optimized Results

Ideally suited for rack-level cooling and specifically designed for high return air temperatures, the Liebert CRV optimizes air distribution and maximizes eiciency, delivering both cost and energy-related savings.

Eiciency is further enhanced through the use of the environmentally friendly R410A refrigerant which ensures constant operation at the highest eiciency levels.

The Liebert CRV is also designed to optimize installation and minimize start up, connection and labor investments. The unit is available for integration with existing racks or as a bundled solution combined with racks, UPS and monitoring capabilities.

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.

Energy Eicient Cooling

The integrated Vertiv ICOM Control, equipped with up to 10 rack temperature sensors, continuously monitors the heat load of the racks and regulates the Liebert CRV, ensuring it provides the most eective level of cooling while at the same time delivering energy savings. Variable capacity compressors modulate the cooling capacity, thus reducing input power with partial loads. EC Fan technology regulates airflow and reduces fan input power.

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.

Vertiv™ Liebert® CRV from 10 to 60 kW

Data Center Rooms and Edge Locations With Up to 10 Racks

The Liebert® CRV is installed in close proximity to servers for installations relating to network access cabinets and small computer rooms, regardless of the presence of a raised floor. The cooling unit, equipped with ten temperature sensors, modulates the airflow to match the real-time cooling requirements of the server.

Direct Expansion Solution

When a chilled water system and physical building limitations restrict the installation of chillers, a direct expansion solution is the ideal choice.

In the event that internal and external units are installed in close proximity, direct expansion units are able to deliver significant reductions in installationrelated time and costs. One of the
