Liebert Economizer Solutions
Liebert Economizer Solutions

Lower Cooling Energy Consumption by up to 50%. Fluid and air-side economizers take advantage of cold outside temperatures to provide “free-cooling” cycles that reduce or eliminate the operation of data center precision cooling system compressors and pumps. Using economizers, you can lower cooling energy usage by up to 50%, depending on the average ambient temperature and humidity of your site.

Liebert GLYCOOL economization is available on Liebert DS and Liebert Challenger 3000 precision cooling systems. Liebert CW and Liebert Challenger 3000 are compatible with Chiller Plant economization. Liebert CW and Liebert DS downflow models are compatible with Liebert Air Economizer.
