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.
