Nautilus Data Technologies recently completed independent testing of its EcoCore Facility Cooling Distribution (FCD), subjecting the system to real-world operating conditions across a range of pressure, flow, and temperature parameters representative of current and next-generation GPU cluster deployments. The results exceeded the company’s own stated specifications across every key metric.
What the Testing Validated
The EcoCore FCD entered testing with a rated capacity of 3.2 MW per unit. Under N-mode dual-pump operation, demonstrated performance came in above 4.1 MW. Additional validated outcomes include:
- Approach Temperature Difference (ATD) as low as 2°C — the tightest margin in the industry
- Flow rates exceeding 5,000 liters per minute in dual-pump configuration
- Full support for pressure requirements of 2.5 to 4.5 bar, meeting NVIDIA DGX infrastructure specifications
- Confirmed compatibility with GPU platforms on the 2027 and 2028 roadmaps
“These results don’t surprise us; they confirm what our engineering and operations teams have known for years. When you’ve designed, deployed, and operated liquid cooling infrastructure under real production load for over half a million hours, you build an intuition for performance that no simulation can replicate.” — Agustin Roca, Vice President of Product, Nautilus Data Technologies
The 2°C Advantage
NVIDIA’s Vera Rubin platform is designed to operate with facility water supply temperatures up to 45°C, a significant shift from the 25-30°C requirements of prior generations. Nautilus’ 2°C ATD means the EcoCore FCD can deliver compliant supply temperatures regardless of whether the source is warm facility water, a natural body of water, a municipal system, or a closed-loop chiller plant.
That water-source agnostic capability has been validated in open-loop seawater environments, closed-loop chiller systems, and hybrid configurations, making it a forward-compatible foundation for operators building out infrastructure today and in the future.
Built on Operator Experience
The EcoCore FCD is now in its third generation, backed by more than 650,000 unit-hours of runtime across Nautilus’ own infrastructure and enterprise customer deployments. The engineers who designed the FCD are the same ones managing live production escalations, creating a closed loop between design and operations that gets embedded directly into the unit’s control logic, alarm prioritization, and failure handling.
The EcoCore FCD is available globally, with proven delivery times of 12-16 weeks from order. To learn more about the EcoCore FCD performance results, click here.
