Replace the Liebert Challenger 3000 compact cooling system
Integrated Liebert iCOM unit control
Available in upflow and downflow configurations
The Liebert PDX and Liebert PCW compact perimeter cooling systems are designed to replace the Liebert Challenger 3000 compact cooling system. The Liebert PDX exceeds new U.S. Department of Energy minimum efficiency standards for data center equipment, which apply to certain direct expansion systems shipped after Jan. 1, 2016. The thermal management systems include an integrated Liebert iCOM unit control, which features machine-to-machine communication to eliminate conflicts in temperature, airflow, and humidity. Both models are available in upflow and downflow configurations, with the direct expansion system having nominal ratings of 18kW (5 tons), 23kW (6.5 tons), and 29kW (8 tons), and the chilled water system having nominal ratings of 17kW (5 tons) and 29kW (8 tons).
