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 eiciency 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 eiciency
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 eicient and
eective 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 diusers 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
36kW, 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.

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.
