DCX Liquid Cooling Systems has announced the second-generation Facility Distribution Unit (FDU V2AT2), a coolant distribution unit designed for large-scale AI data center deployments. DCX says the system is optimized for 45°C warm-water cooling to support NVIDIA NVL72 GB200 and GB300 Blackwell, and Vera Rubin architectures.
According to DCX, the FDU V2AT2 provides up to 8.15 MW of heat-transfer capacity and a “record breaking flowrate,” enabling 45°C warm-water operation. DCX notes that operating at 45°C can eliminate the need for chillers on the heat-rejection side in many deployments.
DCX also says the FDU V2AT2 includes a built-in heat exchanger described as “the most capable heat exchanger in the industry,” and that this supports heat reuse and “chiller-less heat transfer.”
“As the datacenter industry transitions to AI factories, operators need cooling system that won’t be obsolete in one platform cycle,” said Maciek Szadkowski, CTO at DCX Liquid Cooling Systems. “The FDU V2AT2 replaces multiple legacy 1.3 MW CDU’s and enables 45°C supply water operation. This new category of CDUs, has minimum thermal loss with AT2 approach temperature, and provides multi-megawatt cooling at the hall level. That opens a clear path to NVIDIA Vera Rubin architecture and beyond while simplifying cooling loop topology and significantly reducing both CAPEX and OPEX of datacenter liquid cooling system”
