Product Description 2.2 Operational Overview - Water/Glycol Cooled Model The water/glycol cooled XDF model employs a single-stage cooling system rated at 14kW to supply cooling air to the rack-mounted equipment. A bank of fans circulates this cooling air through the elec- tronic equipment in the XDF (see Figure 1). An evaporator coil extracts heat from the circulating air. That heat is transferred to a brazed plate condenser at the top of the XDF, transferred to the cooling water or glycol sol

XDF Components 3.1.5 Environmental Control The XDF supplies cooling air—68°F to 77°F (20-25°C)—to electronic equipment in the rack-mount equipment compartment. In normal operation, six fans at the right front corner of the XDF circulate cooling air through the equipment compartment. The laterally circulating air absorbs heat generated by the electronic equip- ment and transfers the heat to an evaporator coil at the right rear of the XDF. The heat is removed differently in the self-contained,

XDF Components 3.2.2 Drycooler Loop The water/glycol cooled XDF model requires an external supply of coolant, either water or glycol, to remove heat extracted from the XDF. Contact the factory for drycooler requirements when connecting multiple XDF units. For information on setting up a drycooler system, contact your local Liebert representative.
