3.2.2Drycooler 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.
