DCX Liquid Cooling Systems Announces New 8MW Coolant Distribution Unit, Optimized for 45°C Warm-Water Cooling in Next-Gen NVIDIA Vera Rubin AI Deployments
DCX Liquid Cooling Systems is proud to announce the second generation Facility Distribution Unit (FDU V2AT2). Designed to support the infrastructure shift driven by AI deployments at scale, new CDU supports 45°C warm-water cooling for NVIDIA’s NVL72 GB200 / GB300 Blackwell and Vera Rubin architectures.

The Facility Coolant Distribution Unit—the new generation of liquid cooling for hyperscale data centers.
FDU V2AT2 delivers up to 8.15MW of heat transfer capacity while providing record breaking flowrate, enabling 45°C warm-water operation—temperature level that can eliminate the need for chillers on the heat-rejection side in many deployments. This new cooling system has also built in most capable heat exchanger in the industry, which further enables heat reuse and chillerless 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. “The FDU V2AT2 replaces multiple legacy 1.3MW CDUs 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.”
Purpose-Built for 45°C Warm Water and Chillerless Heat Rejection
NVIDIA has highlighted 45°C water supply as a key design point for Vera Rubin rack-scale systems—explicitly enabling data centers to operate without traditional water chillers in the cooling plant for these workloads.
The DCX FDU V2AT2 is engineered to take full advantage of that shift by supporting ASHRAE W45 / W+ warm-water classes and maintaining tight control to avoid condensation, helping operators move from refrigeration-centric cooling to a simpler, more scalable warm-water approach.
From “Row CDU” to Facility-Scale Distribution
Unlike CDUs designed for a single row or small cluster, the FDU 2 is engineered for a new cooling topology that supports complete data halls / facility installations, efficiently supporting large-scale, high-density AI server racks with high flow, high availability and sustainable 45°C temperature class operation.
Key capabilities include:
- Industry record 8.15MW heat transfer (cooling) capacity, supporting hyperscale AI growth
- Record breaking 550 m³/h flow rate required by 45°C warm-water cooling supporting chillerless heat rejection strategies
- Most capable heat exchanger in CDU with 2°C approach temperature for heat reuse and low cost heat rejection
- 4 pumps in N+1 redundant configuration for high availability
- Built in comprehensive water quality control in line sensors and water treatment system
Availability
The DCX FDU V2AT2 is available for hyperscale and high-density AI data center projects effective immediately. Reference architectures, integration guidance, and project sizing support are available upon request.

Philip Morris International Urges FDA Advisory Committee to Recommend Authorizing ZYN as a Modified Risk Tobacco Product23.1.2026 16:15:00 EET | Press release
Experts from Philip Morris International (PMI) (NYSE: PM) yesterday presented scientific evidence to the U.S. Food and Drug Administration’s (FDA) Tobacco Products Scientific Advisory Committee (TPSAC) as part of the FDA’s process for a Modified Risk Tobacco Product (MRTP) designation for their ZYN nicotine pouch products. This designation would allow PMI’s U.S. family of businesses to communicate to U.S. legal-aged, 21+ adult cigarette smokers that switching completely to ZYN reduces their risk of many smoking-related diseases and we look forward to a decision by FDA. "The FDA’s Center for Tobacco Product’s (CTP) mission is to make smoking-related disease and death a part of America’s past,” said Keagan Lenihan, Chief External Affairs Officer for PMI U.S. “Smoke-free products, like ZYN, play a critical role in helping CTP achieve this mission and provide adults who smoke with important information to guide their choices and a real opportunity to change.
