GPU WORLD · GW-LC-CDU-65L
65 kW planning class liquid-to-liquid rack CDU
Multi-server sizing reviewSize a shared CDU for several GPU servers. Confirm each node’s liquid load, manifold branch duty and facility-water envelope before setting the rack design.
Fit and compatibility
- Provide each node’s design liquid load, minimum flow and allowable coolant supply temperature. Identify which nodes can be isolated during service.
- Confirm facility water flow, pressure and worst supply temperature, plus the rack or row footprint, equipment weight and electrical capacity.
Scope of supply
- Define the CDU, rack manifold interfaces and isolation points. Document whether redundant pumps, leak detection, a controls gateway and spares are required.
- Request vendor performance maps for the selected fluids and operating temperatures. Agree on power, monitoring and service clearances.
Operating conditions
- Add the coincident liquid loads for the installed nodes and document any future load allowance separately. Keep the residual air heat in the room cooling budget.
- Compare the combined load with the selected unit’s capacity at actual facility and equipment loop flows and approach temperature. Treat 65 kW as a planning class.
- Use the most demanding branch to establish available pump head. Evaluate manifold pressure and flow with nodes connected or isolated and at the specified filter condition.
Acceptance checks
- Bring nodes online in stages and record both loop flows, coolant temperatures, pump duty and branch flow under the agreed combined load.
- Exercise node isolation, controls alarms and any specified pump failover. Confirm that the remaining nodes stay inside their approved limits.
