The Liebert XDR-W cooling modules are attached to the back of your selected racks, drawing hot air from the rack and cooling it to the point where the impact on the room is close to neutral, then discharging it back into the room. These modules are connected to a Liebert XDP-W coolant pumping unit, which acts as an isolating heat exchanger between the building chilled water source and the circulating cooling water.
The modular and adaptive design of the Liebert XDR-W unit also allows it to be easily added as the demand for cooling increases.
Flexibility:
Installs and configures easily
Allows scalability for future growth.
Provides flexible configuration to eliminate hot spots.
Higher Availability:
Provides built-in redundancy: A dual pump in the coolant distribution unit will keep the fluid flowing; if a fan in the cooling module shuts down, the others keep running.
The pumping unit maintains the coolant to the XDW-R at a temperature always above the actual dewpoint, to prevent condensation.
