System Description

1.11 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.

1.11.1 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. The one-shot flexible pipes are charged at the factory with R134a. Connection to the prefabri-

cated piping assembly is a threaded coupler. For information on acquiring the correct kit for your

installation refer to DPN000780, available by calling 1-800-LIEBERT and from your local Emerson

Network Power representative. Contact the factory when ordering additional flex piping kits for Lie-

bert XD systems installed before 2007.

Prefabricated Headers

Field piping kits are available in several versions

• 10 ft. (3.05m) with 5 or 10 ports

• 8 ft. (2.44m) with 2 or 4 ports

Each version is available in two pipe sizes:

• Supply pipe: 1-1/8"; return pipe: 2-1/8"

• Supply pipe: 1-3/8"; return pipe: 2-5/8"

Each kit contains one (1) supply pipe and one (1) return pipe. Each port has a threaded coupling at

the end with automatic shutoff when disconnected. Each port also has a ball valve for manual shutoff.

For more information refer to section 3.13 - Liebert XD Piping System Design.

Liebert XD Connection Port Kit

The connection ports in the Liebert XD Field Piping Kits are available as Liebert XD Connection Port

Kit. Each port has a threaded coupling, with automatic shutoff when disconnected, at the end. Each

port also has a ball valve for manual shutoff. Each kit contains one supply and one return port. Two

kit sizes are available:

• Supply pipe: 1-1/8"; return pipe: 2-1/8"

• Supply pipe: 1-3/8"; return pipe: 2-5/8"
