Public CDU specification dataset

What you can answer with it

• Compare CDU capacity across suppliers without comparing a rated figure against a nominal one.
• See which suppliers publish a duty point at all, which is itself a procurement signal.
• Cite a capacity with its source rather than with a vendor deck.

How the rows were built

1. Rows are generated from the product records on this site, not maintained separately. A correction to a record changes this dataset on the next build.
2. A figure is taken from a reviewed claim when one exists, and from the supplier's published specification otherwise. The evidence column says which, in every row: “As published” means no editor has yet read that figure against its source.
3. Values are shown as the supplier stated them alongside a canonical unit, so 2 MW and 2,000 kW are one figure rather than two.
4. A blank is written as “Not stated”. No figure is inferred from a comparable product, a datasheet family, or a press release adjective.

The full editorial standard, including how sources are ranked and how project stages are labelled, is on the methodology page.

Data dictionary13 columns

supplierSupplier

The manufacturer named on the product record.

productProduct

The supplier's own model name, not a normalized family.

statusLifecycle

Availability as the supplier states it: shipping, announced, or withdrawn.

capacityRated capacity

Headline thermal capacity, shown as published with a canonical unit beside it.

dutyPointDuty point

The conditions the capacity holds at. “No duty point stated” means the supplier published none.

flowTotal coolant flow

Secondary-loop flow as published. Flow per kilowatt is a separate claim and is not mixed in here.

approachApproach temperature

Difference between facility-water supply and technology-water supply at the rated point.

fluidSecondary fluid

Coolant the technology loop is rated for.

footprintFootprint

Physical dimensions or rack units as published.

evidenceLevelEvidence

Who stands behind the capacity figure. “As published” means no editor has read it against its source yet.

sourcesSources

Count of cited sources on the underlying record.

reviewedReviewed

When a human last read the record this row came from.

recordRecord

Canonical URL of the record, so every row is traceable.

Versions and change log

This file is 2026-08-09, generated 2026-09-24T05:08:33.636Z from 7 records. No publish has changed this file since versions started being recorded, so the version quotes the most recent review across those records instead. The rows themselves are always regenerated from the records, so a correction reaches the file as soon as it reaches the record.

No published change has touched a record in this file yet. When one does, it appears here rather than only in the file.

Formats and licence

• CSVAvailable at /datasets/cdu-specifications/data.csv, RFC 4180 quoted.
• JSONAvailable at /datasets/cdu-specifications/data.json, with the same columns and row order.
• ParquetNot published. The row counts here do not justify it yet, and offering a format we do not regenerate would be worse than not offering it.
• APINo query API. The JSON file is the whole dataset, so fetching it is the API for now.
