What Is Facility Supply/Return Headers?_
These headers form the backbone of a facility-scale liquid cooling loop, typically branching from coolant distribution units or heat exchangers to serve multiple rows of racks. They operate as a closed system separate from the IT equipment's internal cold plates and rack manifolds. Flow balancing and isolation valves are installed along the headers to allow maintenance on individual racks without shutting down the entire loop.
Technical Details
The actual facility design defines header capacity, materials, joints, branch interfaces and monitoring points. Those attributes cannot be inferred from the header label or a generic rack type. Connection, testing and operating work remain with the appointed facility and cooling parties; no joint-selection or commissioning method is supplied.
How Leviathan Systems Works with Facility Supply/Return Headers
The customer and OEM appoint qualified parties for the applicable cooling-system work and its acceptance. Leviathan does not install, connect, test, commission or maintain liquid systems. Any separately agreed physical IT installation or cabling work retains its own authorized scope and handoff.
