Every note here comes out of the same question from a different buyer: will this rack hold the machine I am about to order? The answers are arithmetic — a 1,600 kg frame at a 4× safety factor, a 132 kW cabinet that must move roughly 39,600 m³/h of air if you try to cool it with fans, a manifold loop that needs 25–80 L/min of PG25 at 1.5× working pressure before the first hose is ever crimped.
We publish the numbers because the numbers are the product. Where a figure belongs to the wider industry — an NVL72 reference footprint, a containment PUE spread, a busbar benchmark — we say so plainly and link the boundary between our claim and the industry's.
Start with the power-density guide if you are sizing a row; start with the containment comparison if you are retrofitting a hall you inherited.
Sizing first. kW decides the cooling path; the cooling path decides the frame, the depth and the feed class.
Contain second. Containment is the cheapest kW you will ever save — and the easiest to retrofit badly.
Integrate third. Busbar and coolant belong in the drawing before the order, not in the aisle after it.
Short, numeric briefs on the three decisions that decide an AI rack row: how many kilowatts a cabinet may carry, which airflow boundary to seal first, and how much of the power-and-coolant integration belongs in the factory instead of on your floor. Every figure is either a published industry benchmark or a RackForge factory test record — no adjectives standing in for data.
132 kW per cabinet · PUE 1.84 → 1.65 · 1.5×/24 h pressure holds — the numbers behind the notes
Power density sets the frame, containment sets the efficiency, and pre-integration sets the schedule. Read them in that order if you are sizing a row from scratch.

The industry-average cabinet now draws about 27 kW — 4.5× the old 6.1 kW baseline — and an NVL72-class build pulls roughly 132 kW. Where air cooling stops at ~40 kW, what a liquid-ready frame must carry, and the six-line checklist to size a row before you order it.

A measured case took an uncontained hall from PUE 1.84 to 1.65. Hot-aisle containment can save a further 43% in cooling energy cost — but only where a room-level ceiling return and fire treatment already exist. The physics, the premises behind the numbers, and a six-point priority check.

Field-integrated rows eat 2–3 weeks of trades' time; pre-integrated rows rack on arrival. The overhead benchmark (400 kW per rack position, ≤8,000 A, 85% faster deployment), the three factory checks that make it real, and the delivery list to demand in every crate.
