Flush and fill is where liquid-cooling turnover gets stuck.

The work gets done. Proving it, loop by loop, to a commissioning agent is where days disappear.

Every weld and fitting in the wetted path needs cleaning and passivation records.

Records end up scattered

By closeout, field records sit across checklists, photos, emails and several spreadsheets. Someone has to rebuild the story for the CxA.

Cold-plate performance issues are being traced back to incomplete flushing or filling that left particles in the loop.

Every project asks for something different

There is still no single end-to-end standard for liquid-cooling pre-commissioning, so each owner and CxA sets their own list.

  • Photos in a group chat, not tied to a loop
  • Missing items found when the CxA reviews

With LoopReady

  • One record per loop, built as you work
  • Every item names its evidence and the guidance behind it
  • Open items flagged before the report goes out

Three steps, one loop at a time.

1

Describe the loop

Loop type, coolant, stainless, cleaning method, drain access and witness. The checklist adapts to your answers.

2

Log evidence on site

Tick each item, enter your measurements, and see at once whether they meet the project criteria.

3

Send the readiness report

Status, open items, readings and sign-off lines, ready for your CxA or the owner.

Free checklist

Build your flush & fill checklist.

Each item names the evidence to keep and the guidance it comes from. Enter your project's acceptance criteria once, and every measurement is checked against them. Your entries stay in this browser.

Readiness report

Hand your CxA a report they can sign.

Generated from your checklist and readings. It updates as you keep working.

  • Ready or not-ready status at a glance
  • Progress by phase and every open item
  • Every measurement against its criterion and source
  • Your readings log and notes
  • Contractor and witness sign-off lines

Enter your work email to generate the report for this loop. The blank checklist template downloads as a spreadsheet.

Your email identifies the report and lets the person building LoopReady follow up once about it. Other emails only if you tick a box above.

Questions

Something else? Ask when you get the template by email; replies come from the person building LoopReady.

Is it really free?

Yes. The checklist, acceptance criteria, readings log and readiness report are free. We ask for an email to generate the report, and the blank template downloads right away.

Where is my data stored?

Your checklist, criteria, measurements, notes and project names stay in your browser on this device. When you generate the report, we receive your email, company, role, loops per month, who does your flushing, the boxes you ticked, the loop type, how far the checklist is completed, how many criteria are confirmed or out of spec, and the link you came from. We also count anonymous page usage, without cookies.

Which guidance is it based on?

The OCP guidelines for TCS pre-commissioning, the OCP integration and logistics white paper, the ASHRAE TC 9.9 bulletin of May 2026 on coolant integrity and readiness, plus Vertiv and Schneider Electric deployment guidance. Where sources differ (for example on chemical cleaning), the item says so. Sources are linked at the bottom of the page.

Does it replace my CxA's or manufacturer's requirements?

No. It helps you prepare the evidence they ask for. Manufacturer instructions, site procedures and your commissioning authority always take precedence. The OCP values are only a starting reference: your project spec sets the acceptance criteria.

Who is behind LoopReady?

LoopReady is built by NEOO Technologies, founded by a QA and test management lead with 15 years of experience in test evidence and acceptance.

Your next loop is ready to document.

Start from the OCP reference values, then enter your project spec.
