Liebert Custom Air Handling Units
Mechanical PUE less than 1.2 as part of a system
Our mission-critical air handlers with Liebert iCOM™ controls deliver efficient,
reliable and cost-effective management of heat in large data centers.
Multiple economization options available
We offer the largest selection of air handling solutions, combined with the expert
guidance to help you select, implement and maintain the right technology to ensure
delivered performance for the lifetime of your data center.
Self-optimizing controls reduce over-cooling and
under-cooling
Liebert Chilled Water Air Handler
The Liebert Chilled Water Air Handler Unit is the industry’s most advanced
chilled water cooling system, providing you with maximum thermal control in
your data center.
Economical Deployment. It maintains conditions at a wide range of return air
temperatures and is easy to commission and service, helping to boost productivity
and reduce installation and maintenance costs.
Industry-Leading Efficiency. The Liebert Chilled Water Air Handler Unit can deliver
higher-than-average temperatures (65-70°F), with industry-leading efficiency
through the use of for water- or air-side economization and high-efficiency EC fans.
Simplified Maintenance. Maintenance can be performed easily and quickly, as a
result of features such as full-coil cleaning access, front access to V-Bank filters and
single side-piping.
Intelligent Controls. The Liebert Chilled Water Air Handling Unit features
integrated Liebert iCOM unit controls to maximize data center protection,
efficiency and insight. The controls prevent over-cooling and under-cooling through
machine-to-machine communications and advanced algorithms. Teamwork modes
harmonize the multiple cooling units for higher efficiency and protection.
Local Service and Support. All of our solutions are backed by local customer
engineers with decades of data center experience and a network of factory-trained
service technicians.

Liebert Chilled Water Air Handlers are best used with Liebert iCOM™
unit controls, wired or wireless rack sensors, and a Liebert iCOM-S™
system control to ensure that the entire data center system is optimized
with the other components of the chilled water system. Liebert iCOM
control algorithms continuously process readings from the rack inlet
sensors to ensure optimal air flow through the system while supply

air sensors are used to control the unit cooling capacity. Dampers
or exhaust fans are automatically adjusted by the Liebert iCOM unit
control, which also harmonizes the operation of multiple air handling
units to eliminate conflicts in temperature, airflow, and humidity.
