CDU Pump Trip Ride-Through Calculator
A calculator estimates how long a liquid-cooled rack can tolerate a CDU pump trip and how quickly its standby pump must start.
- For
- Liquid-cooled data-center operators and design teams
- Worth noticing
- The calculator assumes equal flow to every rack; a separate full-loop scan accounts for pipework, valves, and rack positions.
Field notes
Inputs include rack heat, per-rack flow, supply temperature, pump coast-down behavior, standby-pump delay and ramp, and rack thermal properties. The calculator's description says it steps cold-plate temperatures forward as pump flow falls, and presents a chart plus a downloadable PDF or shareable result link. Its full-loop service is framed as a proposal request and covers pipework, valves, rack positions, return-water heating, and commissioning flush velocity.
