Public CDU specification dataset
Every coolant distribution unit in this database, with its published capacity, the duty point that capacity holds at, and whether a person has read the figure against its source.

19 rows. Public CDU specification dataset carries its methodology and limits inside the JSON file, so the file can be read without this page.
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
- 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.
- 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.
- 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.
- 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.
What it does not cover
- Coverage is what this database holds, which is not the whole market. Absence from this file is not evidence that a product does not exist.
- A duty point is only present where the supplier published one. Capacities without one cannot be compared with capacities that have one.
- The evidence column says who stated a figure, not that anyone witnessed a test. “Supplier reported” is the most common value in this market and is not a criticism.
- Prices, lead times, and availability are not here, because this site does not hold figures a supplier will not publish.

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statusLifecycle- Availability as the supplier states it: shipping, announced, or withdrawn.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 v4, generated 2026-11-08T10:46:14.837Z from 19 records. The version counts the publishes that changed this file, so it never moves backwards and a citation keeps meaning what it meant. The rows themselves are always regenerated from the records, so a correction reaches the file as soon as it reaches the record.

- 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.

Citing and correcting
Cite it as: DataCenterChill, Public CDU specification dataset (dcc:cdu-specifications), v4, https://www.datacenterchill.com/datasets/cdu-specifications. Quoting a figure without the conditions in its row is the error this file exists to prevent, so keep them together.
A row that is wrong is a record that is wrong. Send the source and the correction reaches the record, this file, and every page connected to it.
