The Liebert XDO draws in hot air through two opposite inlets and discharges cool air down into the cold aisle where the electronic equipment air inlets are located. This flexible, scalable and space saving product mounts to the ceiling requiring zero floor space. The Liebert XDO is a part of our high heat-density cooling product family that utilizes pumped refrigerant technology. The pumped refrigerant operates at low pressure in the system and becomes a gas at room conditions, making it ideal for use around electronic equipment. Since the Liebert XDO always provides 100% sensible capacity, the need for humidification is significantly reduced, further reducing energy usage and maintenance.
