Vertiv introduced the Liebert® XDU, a thermal management system that supports an entire cabinet of liquid-cooled servers and enables drop-in retrofits in air-cooled data centers. The 60kW distribution unit circulates water through liquid-cooled server racks and rejects the heat from the returning warm water into the hot aisle. It uses a closed water loop and requires no new plumbing. The compact system can be placed in the row near the rack it is cooling or along the room’s perimeter. It utilizes integrated Liebert iCOM® controls to regulate supply water temperature and to provide intelligent flow monitoring and alarms.
