3.2Coolant 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.
