Liebert Indirect Evaporative Free Cooling Unit, 150-400+kW

The Liebert Indirect Evaporative Free Cooling Unit improves energy efficiency with potential PUEs under 1.2 with minimal water usage. It includes supplemental DX (direct expansion) or chilled water options for trim cooling requirements.


Highly efficient aluminum air-to-air heat exchanger offers up to 66% efficiency dry and 78% efficiency wet. Supplemental DX or chilled water options available for trim cooling requirements. Advanced monitoring and event notification. Finely tuned controls for balanced operation and cooling.


Highly efficient - mechanical PUE less than 1.2 Lower installation and maintenance costs No outside air into the data center Balanced capacity utilization and efficiency Greater protection Extended dry mode range Less water usage and treatment Downsized electrical infrastructure Controls require little if any customization
