Emerson Network Power has introduced the Liebert® PDX and Liebert PCW compact perimeter cooling systems to help data center managers achieve the highest efficiency and protection with low capital, installation and maintenance costs, as well as the industry’s most compact footprint. The new systems are available in North America.

Suited for small and medium IT spaces and telecommunication 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 center equipment, which apply to certain direct expansion systems shipped after January 1, 2016. For instance, the system in 18kW capacity is 13 percent 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 percent more efficient than the Liebert Challenger, while the Liebert PCW compact chilled water cooling system is twice as efficient.

“Today’s smaller space IT environments are more complex, with data centers 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, 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 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 machine to machine communication to eliminate conflicts in temperature, airflow and humidity, increasing efficiency and providing superior protection across the data center's thermal management system.

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 (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).
