Eight verticals
Every entry below starts with the question that actually decides the build. Answer it yes or no — that is the whole test.
Group A · Decided by the room you have
If the constraint is physical — floor space, an existing building, a plant floor, tenants arriving one at a time — start here.
Can we meter and isolate power per cabinet without touching the tenant next door?
Per-cabinet isolation and metering; mounting positions reserved for intelligent busway and PDU; containment that does not narrow the service aisle.
Aisle rows of 3–8 cabinets · deployed in 2–3 weeks · extended tenant by tenant.
How the aisle goes togetherNobody is on site. What happens when the cooling stops at 2 a.m.?
Self-contained power and cooling inside the enclosure; smoke-sensor interlock and emergency ventilation; remote access and SMS alerting.
27U of IT space in 0.72 m² · installed in about 3 hours.
What is inside the cabinetThe grant paid for the compute. Where does the cluster go if there is no new building?
High-density rows inside an existing room; containment built around the racks you already own; a row designed for the final count so it can be built in phases.
25%+ energy saving on the aisle · start with 3 cabinets, extend the same row to 8.
Design your row firstDoes the equipment room sit in a corner of the shop floor — dusty, hot in summer, and nobody's job to watch?
An enclosure that keeps its own climate; sealed cable entries; a filter and maintenance interval agreed with your facilities team.
Micro-modular package: 3–8 cabinets, in-row cooling, 2–3 weeks.
We do not publish a protection rating for mesh-door cabinets — with a front door above 75% open area, a rating claim would not survive one look at the door. Sealed-door build is a line item; ask for it if you need one.
The package version
Group B · Decided by what you have to prove
If the constraint is documentary — a bid annex, an audit, an uptime commitment, a customer's specification — start here.
Can you deliver batch three identical to batch one, against the same drawing, on a date that does not move?
How U height and depth are decidedDimensional repeatability of ±0.5 mm on fabricated parts; 100% incoming material inspection; the same 2.0 mm uprights and 1.2 mm doors on every unit; one product certificate per unit.
42U = 2000 mm and 47U = 2200 mm · a 40HQ carries about 38 racks loose-loaded, about 20 palletised.
When the auditor asks how we know the floor is safe, what do you hand over — a catalogue page or a test report?
Read the seismic guideThird-party seismic testing (CAICT, 18 pages); reserved positions for dual-path power; ground continuity measured on every unit.
Two third-party reports already on file · 18 + 3 pages · PDF on request.
Can every line on your datasheet be traced to a document we can verify?
See what can be verifiedCertificates with verifiable numbers; records kept through the product life cycle; a certificate per unit and a packing list with serial numbers.
ISO 9001 / 14001 / 45001 · national high-tech enterprise registration · registered trademark · 3 granted utility model patents and 1 software copyright.
The building's cooling is shut down for maintenance twice a year. What happens to the rack?
What is inside the cabinetCooling and power inside the enclosure so the shutdown does not reach the IT load; smoke-sensor interlock and emergency ventilation; alerts that name the row, not just the building.
Single-row intelligent cabinet · 27U · 0.72 m² · self-contained cooling and power.
Still two candidates
Is the constraint the room, or what you have to prove?
The room → Group A. The proof → Group B.
Will anyone be on site when something fails?
No one → Telecom & edge nodes, or Healthcare.
Does a third-party test report have to sit in your bid annex?
Yes → Finance & banking first, then Government & public sector.
Down to two candidates? Open both. The first question on each page is written so you can answer it yes or no.
Reference installations are all in mainland China. We do not publish customer names without consent, and we will not present anyone else's sites as ours.
None of the eight
Describe the room and the constraint instead of the industry — we will tell you which vertical it behaves like, and what we would build for it.
Ask which verticalEvery request is either accepted or explicitly refused — never silently dropped.
What comes back
Documents leave as PDFs, the drawing set goes out for approval, and the quote names the Incoterm and holds for 30 days.
Every request is either accepted or explicitly declined. It is never silently dropped. No reply means it never reached us — send it again and it is treated as a first contact.
