Nautilus Cooling Unit Surpasses AI GPU Performance Targets

Independent performance testing validates EcoCore facility cooling distribution unit capabilities exceeding stated specifications and demonstrates readiness for Vera Rubin-class AI infrastructure and the next generation of high-density liquid-cooled deployments.

San Ramon, CA — May 28, 2026 — Nautilus Data Technologies announced the successful completion of rigorous performance testing of its EcoCore Facility Cooling Distribution Unit (FCD). The results exceeded the company’s previously stated specifications, validating the system for today’s most demanding AI GPU clusters and next-generation platforms targeted for 2027 and 2028 deployments.

Validated performance

• Rated capacity of 3.2 MW per unit, with demonstrated performance exceeding 4.1 MW under N-mode dual-pump operation.

• Approach Temperature Difference as low as 2°C, enabling warm-water free cooling compatibility with Vera Rubin’s 45°C supply temperature specification.

• Support for 2.5 to 4.5 bar technical cooling-loop pressure requirements and flow rates exceeding 5,000 liters per minute in dual-pump configuration.

Prepared for the 2027–2028 GPU roadmap

The EcoCore FCD’s validated 2°C approach temperature advantage means it can deliver compliant supply temperatures from warm facility water, natural bodies of water, municipal systems, or closed-loop chiller plants. Nautilus has validated this water-source-agnostic capability across open-loop seawater, closed-loop chiller, and hybrid configurations—helping data centers protect infrastructure investments through the next GPU generation cycles.
