San Ramon, CA — February 26, 2026 — Nautilus Data Technologies, the pioneer in transformative data center liquid cooling, today announced a major performance expansion for its EcoCore Facility Cooling Distribution (FCD). The company is introducing a high-performance, positive pressure configuration for its Cooling Distribution Units (CDUs), designed to support the escalating thermal and flow demands of the latest processor architectures and to comply with NVIDIA Core certification requirements.
As the data center industry continues towards extreme-density AI and HPC workloads, Nautilus has optimized its modular FCD platform to align with the future of direct liquid cooling (DLC). The new configuration creates an alternative to the unit’s vacuum-based option, leveraging a design using parallel 30HP pumps. The configuration allows the FCD to address the significant pressure drops associated with modern DLC loops and deliver maximum flow rates.
- Supports latest GPU Requirements: The high-pressure design allows both pumps to operate simultaneously at 100% speed, providing the full-rated flow and thermal capacity required of today’s greatest chip demands (such as NVIDIA Rubin GPU).
- Extreme Density: By operating pumps in parallel, the EcoCore FCD approaches a consistent cooling capacity of 4MW.
- Enhanced Redundancy: The added configuration features internal pump-level redundancy, complementing Nautilus’s existing system-level redundancy.
- Integrated Filtration: The configuration includes robust, integrated filtration to ensure long-term loop integrity and performance.
“With this new configuration, we’re not just meeting the market where it is currently, but aligning with the future roadmaps of major chip manufacturers,” said Rob Pfleging, CEO, Nautilus Data Technologies. “Nautilus provides the high-pressure, high-flow capabilities required to cool every direct liquid cooling chipset currently available, as well as those projected for the future.”
The positive pressure configuration will become the default for the EcoCore FCD to ensure broad compatibility with AI infrastructure. In addition, Nautilus will continue to offer its proven proprietary leak-prevention configuration.
“This expansion gives our customers the flexibility to choose the right solution for their specific infrastructure, whether that is the extreme density support of our parallel pumping mode or the leak prevention of our vacuum mode,” said Pfleging.
