Emerson Network Power Introduces Three New Models Of Liebert DS Precision Cooling System

Emerson Network Power announced the availability of three new models of the Liebert DS™ precision cooling system. Previously available in only downflow configurations, the new Liebert DS models provide support for applications that require cooling delivered from the top of the unit (upflow) with capacities of 28, 35 and 42kW. According to the company, with this extension, virtually any precision cooling application can benefit from the advanced controls, variable capacity and easy transition to green refrigerants that are provided by the Liebert DS system.

"The Liebert DS represents the next-generation of precision cooling system with features that provide more efficient computer-grade control of room temperature, humidity and air quality in critical facilities," said Ron Spangler, Senior Product Manager for the Liebert DS at Emerson Network Power. "This new family of upflow models extends the application of the Liebert DS beyond the raised floor to any environment that requires precise, highly reliable environmental control."

The Liebert DS is claimed to be the first and only precision cooling system to use digital scroll compressors, which allow unit capacities to quickly adapt to changing room conditions. The equipment is capable of responding to changes as small as +/- 1 degree Fahrenheit (Celsius) and +/- 1 percent RH (relative humidity). As a result, it is claimed that the Liebert DS can be precisely matched to the exact requirements of the room at any time, creating significant energy savings and better protection of business-critical applications.

The Liebert DS also takes advantage of the Liebert iCOM™ control system, which provides advanced diagnostic and maintenance support and enables multiple units to communicate and work together as a system to precisely control temperature and humidity across a room. The iCOM setup wizard automatically sets up all the units in a room from a single location so the efficiency of the entire cooling system can be optimized. The Liebert DS also features a patented Paradenser condenser system that enables units to use green refrigerants with no loss in capacity.
