Liebert PCW Chilled Water Cooling System, 11-29kW, offers the industry’s highest efficiency, protection and capacity per footprint for server room cooling. network closets and other small space air conditioning.
The Liebert PCW is highly configurable and available in a wide range of capacities. The units feature variable speed EC fans that reduce motor energy usage by 10-30%, compared to standard AC motors, and are more efficient than centrifugal blowers even when operating at 100% fan speed. The units feature motorized control valves that control water flow and are managed by the Liebert iCOM unit control to maintain the desired cooling capacity. The Liebert PCW offers unique, floor-level air discharge that reduces the mixing of hot and cold air to improve efficiency. Downflow models provide front, left side and right side discharge and upflow models provide front and rear return options.
