INTEGRATED SYSTEM OPTIMIZES EFFICIENCY
Cooling equipment accounts for as much
as 40% of data center operating costs. 1
The Liebert DSE direct expansion cooling system -
A chilled water cooling system for a 1MW data center
each component operates at the industry's highest
uses around 4 million gallons of water annually.2
efficiency, and the lowest total cost of ownership.
Medium and large data centers need to
conserve energy and water
while preserving availability.

The Liebert DSE
indoor computer room air
conditioning (CRAC) unit
World's most efficient DX
cooling system
The Liebert® DSE™ is the world’s most energy-efficient
DX cooling system, and uses no water.
Up to 50% more efficient than legacy cooling
systems alternative technologies, the Liebert DSE
improves thermal management and control, while
cutting energy costs and saving water.

The result? A 23% reduction in power consumption
without economization.
