01
Will it fit?
Equipment keeps getting deeper and heavier, so the enclosure can no longer be built to the old specifications. Match the width, the depth and the mounting-hole spacing first.
AI RACK ENCLOSURES · COLD AISLE CONTAINMENT
Put the rack’s dimensions, load and tolerances,
down on paper first.
We make two things: the rack enclosure itself, and the contained aisle between racks. The parameters on this page are given from public standards and datasheets, each one cited to its source; the parts we do not make are also written on the page.
- Mounting width19 in (482.6 mm) · EIA hole spacing
- Height options42U / 45U / 48U / 52U
- Static load1,360 kg (3,000 lb) · UL 2416 rated
02
Will it seal?
Cold air that bypasses the equipment and goes straight back to the return grille makes the cooling pointless. Match the aisle width, the rack width and the ceiling height first.
03
Who makes it?
A rack is sheet-metal work. Look at cutting, bending, pretreatment, and the inspections done before it leaves the factory.

The aisle between two rows of racks
Industry research estimates that in a conventional data room about 60% of the cold air returns to the return grille without passing through the equipment. Cold aisle containment seals the aisle in front of two rows of racks — a panel on top, doors at both ends, seals in the gaps — so the cold air can only enter from the front of the equipment.
Contained
Cold aisle
- Aisle width1,000 / 1,200 / 1,800 mm (1,200 is the common value)
- Compatible rack width600 / 700 / 800 mm
- Compatible rack height42U–48U, with and without base
- Per-rack capacityup to 20 kW per rack after containment (7–8 kW per rack with conventional raised-floor supply)
What we do not do
- 01 No cooling source — CDUs, cold plates, quick couplings and manifolds are all outside the scope of this site.
- 02 No power — rack PDUs, UPS and busway are all outside the scope of this site.
- 03 No software — monitoring and DCIM are outside the scope of this site.
Two things only: the enclosure, and the structural parts that seal it.

A rack is sheet-metal work
- 01Cutting and punchingCut and punch to drawing. Sheet thickness and hole diameter are checked piece by piece against the drawing.
- 02Bending and weldingBend angle and weld position are checked piece by piece against the drawing.
- 03Pretreatment and coatingPowder coating after five-stage pretreatment; 500 h salt spray per ASTM B117 / D610-01.
- 04Pre-shipment inspectionDoor opening and closing, locks, rail hole spacing, grounding continuity, appearance and colour code — every item checked before packing.

Five things to send when you ask for a quote
- 01 · Equipment size and weight
- A current model list or drawing is fine
- 02 · Quantity and delivery location
- Including the destination country and city
- 03 · Aisle width and number of rows
- The containment is calculated from this
- 04 · Colour and markings
- A colour code or a reference part
- 05 · Drawing or reference model
- If there is no drawing, give a reference model
