1.10 Liebert XD Piping
Liebert XD Piping is prefabricated distribution piping that is installed in anticipation of a growing sys-
tem. Liebert XD cooling modules are added as required and are quickly made operational with flexible
connection piping with threaded couplings. This unique system allows the room cooling capacity to
increase to more than 30kW per rack with no additional disruptive piping installation. The flexible
connection piping also allows the cooling modules to be re-positioned without interruption in operation.
1.10.1 Liebert XD Field Piping
Flexible Piping Kit
Flex pipe kits are available in lengths of 4, 6, 8 and 10 feet (1.2, 1.8, 2.4 and 3 meters). Connection
style to the module end may be straight or 90 degrees with one-shot style couplings or removable cou-
plings. Connection to the prefabricated piping assembly is a threaded coupler. For information on
acquiring the correct kit for your installation refer to DPN000780_Rev1, available by calling
1-800-LIEBERT and from your local Emerson Network Power representative.
