Emerson Network Power announced a capacity expansion to the upflow configuration of the Liebert DS precision cooling system. It is now available in nominal ratings of 53 (15 tons), 70 (20 tons), 77 (22 tons), and 105 kW (30 tons). Previously available only in capacities of 28, 35, and 42 kW, the upflow model of the Liebert DS precision cooling system provides support for applications that require cooling delivered from the top of the unit in data centers or telecommunications environments that do not have a raised floor. The Liebert DS, which is also available in downflow models from 28 to 105 kW, is the first and only precision cooling system to use digital scroll compressors.
