Achieving Success with EcoCore

Understanding Our Advanced Water Cooling Technology

custom cooling image #1
Server heat can be captured by traditional hot aisle, rear‑door cooling, direct‑to‑chip, or immersion.
An eductor solution creates a vacuum, drawing air into the pipework in the event of a leak.
This self‑contained design prevents leaks and maintains system integrity.
custom cooling image #2
Each module contains four Cooling Distribution Units (CDUs), offering 835kW or more of heat rejection to ensure system redundancy and reliability.
Nautilus' cooling technology utilizes a water-based heat sink cooling process as the external heat rejection system for the data center.
custom cooling image #3
The design is N+1 redundant, adaptable to environmental changes, and compliant with AHJ requirements for water temperature. The zero‑water cooling system eliminates the need for chillers, CRACs, and CRAHs.
Adept at utilizing a wide array of water sources, including freshwater, greywater, and saltwater.
