Vertiv has introduced a liquid cooling distribution unit in Europe.
The Liebert XDU, launched in the US in 2019, allows techniques including direct-to-chip liquid cooling to be deployed in air-cooled data centers. It is now available in Europe, the Middle East, and Africa.
The XDU is designed to be water-efficient and to support high-density data centers running applications such as analytics and machine learning. It is available in two capacities; 450kW, and a model capable of up to 1368kW.
The system can be placed in the row near the rack it is cooling, or along the room’s perimeter. It regulates liquid quality, flow, and pressure, so liquid-cooled servers can be deployed in regular data center environments.
The XDU circulates water through liquid-cooled server racks and then rejects the heat from the returning warm water. The heat can either be taken off by the data center's existing air-cooled environment, or be captured and used to warm nearby offices, homes, or farms
The system includes controls to vary the pump speed to get the best water flow and temperature and to provide flow monitoring and alarms.
“High-performance computing applications such as artificial intelligence and augmented reality are growing in popularity at the same time that data centers are working to reduce their energy consumption and pushing the industry to find new, more sustainable solutions,” said Roberto Felisi, senior global director and EMEA business leader for thermal management, Vertiv. “Many colocation providers who have traditionally relied on air cooling are now hosting applications with higher power processors that require more efficient heat management solutions like liquid cooling."
“Liquid cooling is not a new technology but we’re now seeing a real opportunity in the market to drive more innovative thermal management solutions. The Liebert XDU solution offers the possibility for Vertiv's customers to introduce rack-level liquid cooling and reap the environmental benefits,” said Jon Summers, scientific lead in data centers at RISE - Research Institutes of Sweden. “We look forward to support Vertiv’s R&D roadmap and to combine their engineering excellence with the rigorous analysis and testing capabilities of RISE as part of our ongoing research partnership. This will bring a deeper technical understanding of sustainable and effective approaches for the data center industry.”
