EcoCore RCD
Compact, High-Density Cooling at the Rack Level
EcoCore RCD
In-row Cooling Distribution Unit
The EcoCore RCD is Nautilus’s in-row Cooling Distribution Unit, designed to deliver localized, high-capacity cooling directly to the row or perimeter. With up to 2,000 kW of heat rejection in just 1.2 m² of space, the RCD supports liquid-to-liquid (L2L) cooling for AI-ready deployments where footprint and scalability are critical. Featuring adaptable flow and pressure ranges, thermal load balancing across linked units, and built-in redundancy, the RCD enables operators to efficiently cool today’s densest compute clusters while future-proofing for tomorrow’s workloads.
