Data center cooling system

Emerson Network Power has released a precision cooling system capable of handling upflow and downflow configurations for precision cooling.


The Liebert CW precision cooling system by Emerson Network Power is a chilled water-based computer room air-handling unit available in upflow and downflow configurations with cooling capacities up to 400 kw. The system, which uses the building’s chilled water supply as the cooling source, offers precision cooling and humidity control matched to the needs of data center equipment. The cooling system is in accordance with the International Building Code, California Building Code, and California’s Office of Statewide Health Planning and Development for operation after the event with an importance factor of 1.5. The Liebert CW uses the Liebert iCOM control system that enables multiple control algorithms depending upon the type of sensors connected. Intelligent control capabilities give data center managers the ability to tune their cooling systems to dynamically adjust airflow patterns by controlling the speed of the electrically commutated plug fans to allow cooling unit capacities to adapt quickly to changing room conditions.
