2.2.1 Vertiv™ CoolPhase CDU
The Vertiv™ CoolPhase CDU is an indoor chiller that connects directly to the Vertiv™ Liebert® DCD cooling modules and is
designed to circulate and control coolant to single-phase liquid cooled IT equipment. The CoolPhase CDU keeps the coolant
temperature above the room dew point by using sensors.
The CoolPhase CDU is a chiller with two distinct circuits:
• A refrigerant circuit. This circuit is a dual direct expansion circuit. It contains tandem scroll compressors,
expansion valves, brazed plate heat exchanger, and piping.
• A water/glycol circuit. The water/glycol circuit uses two circulating pumps, a brazed plate exchanger, and piping.
Heat removal is accomplished by using condensers connected to the dual direct expansion circuit. Heat rejection is an
outdoor air cooled condenser. See Figure 2.1 on the facing page .
