The market gap · verified 2026-04
One chart, the whole company
Air micro-DCs stop at ~10 kW; data-center liquid starts at 70 kW — as components, not cabinets. The 20–50 kW middle is the entire product. Drag your load and see where it lands.
See the cabinet →THE GAP — US20–50 kW, no facility water: exactly the cabinet we build. Air micro-DCs can’t reach it; data-center CDUs start above it.
Anchors: Schneider EcoStruxure micro DC (air, 3.5–10 kW) · Vertiv VRC-S (~3.5 kW) · Vertiv CoolChip CDU 70 (70 kW L2A) · Asetek InRackCDU (80–120 kW) · STULZ×CoolIT Micro DC (2018, ~27 kW) — vendor data sheets, benchmarked 2026-04.

What's inside, down to the coupling
Your servers slide in and blind-mate through an ORv3-spec manifold and universal UQD disconnects — one sealed loop, leak-monitored end to end. Every part on this schematic links to its public derivation.
Interface ledger →20–50 kW, served by no one
Air micro-DCs end at ~10 kW; DC liquid starts at 70 kW as parts. We build exactly the in-between, turnkey.
Open by interface
ORv3 blind-mate + UQD couplings: any OEM's liquid-ready servers fit. No lock-in by contract or parts book.
Deploy, not construct
A closed loop rejects heat to room air. No chiller, no water lines — power and network are all a site needs.
Honest engineering
Derating curves, room-load worksheets, schematics-not-renders — published before you ask.
Who it's for
Three rooms, one cabinet
Hospitals
On-prem AI next to the PACS suite — in a corridor-side technical room, not a machine room. Patient data stays home.
30 kW — a department's own clusterUniversities
A lab owns serious GPU compute without the university building them a machine room. Grant-friendly, vendor-neutral.
Days — not months, to stand upEdge sites
Storage and compute in offices, branches, light-industrial sites. Unattended does not mean unwatched: telemetry and leak alarms included.
Said plainly
- An L2A cabinet is a heat mover: your room’s AC must extract ≥ 1.1 × full IT load. We publish the worksheet before you buy.
- Cooling capacity roughly halves from 25 °C to 35 °C room air. Any vendor not showing you the derating curve is hiding it.
- Every diagram here is a schematic. No product photographs until the demo unit exists.
Derived in the open
Every number on this site is derived in public on our knowledge hub — load budgets, room loads, derating physics, standards tracking:
Built on open standards — nothing proprietary between you and your servers
