Liebert XDO-Overhead Cooling Module | Emerson Xtreme Density

System Description

1.3Liebert XDO—Overhead Cooling Module

The Liebert XDO ceiling-mounted cooling module draws in hot air rising from densely populated cab- inets, passes it over the Liebert XDO’s coils and exhausts cooled air downward into the cold aisle. The unit is available with optional, flexible metal pipes with quick-connect couplings at each end for easy connection to the refrigerant distribution pipes.
