ENERAL PRODUCT INFORMATION
3.1 Product/System Description
3.2 Introduction
The Liebert XDO is an overhead cooling system designed for installation above heat-dissipating
equipment. A fan draws hot air exhausted from the equipment through two cooling coils and dis-
charges cool air back down to the equipment (see Figure 3 ). The system consists of XDO modules,
XDP/XDC coolant distribution units, power and signal cabling and interconnecting piping (see
Figure 4 ).
Liebert’s XDP/XDC monitors room conditions and prevents coil condensation by maintaining the tem-
perature of the coolant pumped to the XDOs above the room dew point.
