XD In-the-Row Cooling Module, 22-30 kW

Liebert XDH, XD In-the-Row Cooling Module, 22-30 kWThe XDH horizontal row cooler is placed in line with rack enclosures. Air from the hot aisle is drawn in through the rear of the unit, cooled, and discharged into the cold aisle where the electronic equipment air inlets are located. Connects via flexible piping and uses pumped refrigerant technology.

Liebert XDH installs between the protected racks, providing horizontal airflow for the surrounding equipment. Available in nominal capacities of 22 kW (6.3 Tons) and 30 kW (8.5 Tons) for 60 Hz applications; 19 kW (5.4 Tons) and 27 kW (7.7 Tons) for 50 Hz applications. This pumped refrigerant-based system is backed by the Liebert XDC Chiller, or the Liebert XDP Pumping Unit.
