Introducing the Liebert

DSE™ from

Emerson Network Power

In today’s data center, minimizing annual energy usage

while maintaining reliability is increasingly important. While

chilled-water loops operating at elevated temperatures

supported by water-side economizers have helped to

decrease energy usage, new innovations are changing how

the data center industry thinks about direct expansion (DX)

cooling infrastructures with respect to efciency, scalability

and reliability.

One such next generation DX system, the Liebert DSE

from Emerson Network Power, provides the following

key benets:

Industry-leading energy efciency among

DX systems

Hassle-free economization with Liebert EconoPhase™

Precise control and enhanced efciency through

intelligent controls

Uncompromising reliability and 24/7 support

This product brief will provide a thorough overview of

the Liebert DSE system and compare its unique design to

comparable DX and chilled-water cooling solutions you

may be considering for your data center. It also provides a

detailed explanation of the Liebert EconoPhase pumped

refrigerant economizer solution and share specic examples

for how cooling efciency can be maximized intelligently in

accordance with your data center’s ambient climate.

The Liebert DSE direct expansion cooling system comprises

four primary components: the Liebert DSE indoor computer

room air conditioning (CRAC) unit, the Liebert MC™

micro-channel outdoor condenser, the Liebert EconoPhase

pumped refrigerant economizer, and Liebert iCOM™

thermal system controls. The components operate in

harmony to provide the industry’s most energy efcient

operation for a room-based cooling system.

It is important to note that the Liebert DSE is a

complete, integrated system— not a collection

of disparate components.

The Liebert DSE direct expansion cooling system comprises four primary components: the Liebert DSE indoor computer room air

conditioning (CRAC) unit, the Liebert MC micro-channel outdoor condenser, the Liebert EconoPhase pumped refrigerant economizer

and Liebert iCOM control with thermal system manager.

Liebert MC: Intelligent, high

efficiency condensers

Liebert EconoPhase: First ever

pumped refrigerant economizer
