Cooling for smaller spaces

Suitable for small and medium IT spaces and telecomms switching offices, the thermal management systems replace the industry-standard Liebert Challenger 3000 compact cooling system. The efficiency of the Liebert PDX perimeter cooling system exceeds new U.S. Department of Energy minimum efficiency standards for data centre equipment, which apply to certain direct expansion systems shipped after 1st January 2016. For instance, the system in 18kW capacity is 13% more efficient than the efficiency standards. As a family, they offer the industry’s highest net capacity per square foot. The Liebert PDX direct expansion cooling system is 25% more efficient than the Liebert Challenger, while the Liebert PCW compact chilled water cooling system is twice as efficient.

The thermal management systems feature an integrated Liebert iCOM unit control, which provides the highest level of protection and efficiency with fast and easy deployment and commissioning. Liebert iCOM features M2M communication to eliminate conflicts in temperature, airflow and humidity, increasing efficiency and providing superior protection across the data centre's thermal management system.

“Today’s smaller space IT environments are more complex, with data centres putting a focus on infrastructure flexibility, scalability and energy efficiency while maintaining the highest levels of availability,” said John Peter Valiulis, Vice President, North America Marketing and Thermal Management, Emerson Network Power. “The Liebert PDX and Liebert PCW compact perimeter cooling system family offers ideal solutions to these challenges while lowering operating costs and packing a lot of capacity into the industry’s most compact footprint.”

The Liebert PDX and Liebert PCW compact perimeter cooling systems are available in upflow and downflow configurations, with the direct expansion system having nominal ratings of 18kW, 23kW and 29kW and the chilled water system having nominal ratings of 17kW and 29kW.
