1.3 Liebert XDV—Vertical Above-Cabinet Cooling Module
The XDV is installed on top of or above a rack enclosure. It is available with optional flexible metal
pipes with automatic shutoff at the ends for easy connection to the XD Coolant distribution pipes.
This flexible piping is available pre-attached and pre-charged with refrigerant. The Liebert XDV may
be set up in either of two ways:
• The XDV can take hot air directly from an equipment enclosure, cool the air and discharge it
downward into the cold aisle.
OR
• The XDV can draw hot air from the room, cool the air and discharge the cool air downward into
the cold aisle.
