3.2 Coolant Source—Water/Glycol Models
The XDF water/glycol cooled models may be connected to either of two types of coolant sources:
• a closed-loop water system (cooling tower)
• a drycooler loop

3.2.1 Closed-Loop Water System

A closed water supply system is required for efficiency and to protect the equipment from particles
and other contaminants that might obstruct the system’s piping.

!CAUTION

Risk of dirt and debris contamination. May cause condenser clogging.
Do not install the XDF on an open-loop water supply system. Debris carried by the fluid will
clog the XDF’s brazed plate condenser.
