Controls from Emerson Network Power
Emerson Network Power has added Liebert iCOM controls to the Liebert XDC refrigerant chiller. Providing refrigerant circulation and control in applications where the building’s chilled water system is not available, the Liebert XDC with iCOM can cool more than 30 kW per rack and 160 kW per system. The Liebert XDC with iCOM is designed to support the Liebert XD Smart Modules, which are cooling modules that are compatible with the Liebert XD family and feature integrated control boards that enable modulation of cooling capacity and higher efficiency performance. With dynamic fan control, the Liebert XD Smart modules can save 50 to 70 percent in energy costs over traditional precision cooling methods.
Liebert iCOM with CAN-bus communications allow real-time monitoring and data capture of supply and return air temperatures at the rack level, module cooling capacity, and fan status and presents the data in graphical views that easily convey data center conditions to users. Status may be reported back to the DCIM or BMS via Liebert IntelliSlot communications cards. An upgrade kit is available for currently installed Liebert XDC and Liebert XDP units to utilize the CAN-bus communication between the Liebert XD Smart Modules and BMS or DCIM.
