Siemens and Rittal enter into strategic partnership for data center energy infrastructure
In AI data
centers, power densities exceeding 100 kW per rack have become the norm. By
2030, power density could increase more than tenfold. This requires new
architectures for power distribution, cooling, and heat recovery. To address
this, Siemens is partnering with the Friedhelm Loh Group and its largest
company, Rittal, a global provider of racks and standardized infrastructure,
including power and cooling for leading cloud providers.
One of the
first joint solutions will be an application that is housed directly in the
heart of a data center where the server cabinets and data storage are located.
By bundling the power electronics in a separate power rack that supplies the
server cabinets, this type of power supply represents a breakthrough for future
AI applications. Other Siemens and Rittal projects include the development of a
standardized low-voltage distribution system for modular and containerized data
centers as well as optimized solutions for operational and personal safety. The
first customer projects are already being implemented. The collaboration
between Siemens and Rittal is expected to extend to other industries and
applications in the future.
