Product · reference architecture
One cabinet. Cooling, distribution, leak detection — included.
Your liquid-ready servers slide in through ORv3-compatible blind-mate interfaces and universal UQD couplings. One sealed loop rejects heat to room air. Power and network are all a site provides.

What's inside
Click any part — cold plates, manifold, UQD couplings, L2A unit, loop, sensors — for what it is and why it’s specified that way.
Specification
Target specification
| COOLING CLASS | 20–50 kW IT load per cabinet (L2A closed loop, single loop per cabinet) |
| ROOM AIR ENVELOPE | Designed for 25–35 °C room air; capacity derates with temperature — envelope published, per-unit curve from sample testing |
| SERVER INTERFACES | OCP ORv3-spec blind-mate manifold · UQD quick disconnects · any OEM DLC server |
| HEAT CAPTURE | Direct-to-chip share 60–80% (server-dependent); air share absorbed by the cabinet loop |
| ROOM REQUIREMENT | AC able to extract ≥ 1.1 × full IT load; standard single- or three-phase power; no water, no construction |
| COOLANT | PG25 water-glycol, PFAS-free, factory-sealed loop |
| MONITORING | Loop temperature/pressure, leak sensors, remote telemetry with alarms |
| FORM | 42U sealed enclosure · delivered as one unit · commissioning in days |

Honest engineering notes
The three things we will always say out loud
Heat goes to the room
L2A moves heat into room air; the building extracts it. We size the room first — the worksheet is public.
Capacity derates
At 35 °C room air an L2A loop delivers roughly half its 25 °C capacity. Any vendor not showing you this curve is hiding it — ours is public.
Leak risk is managed
Water-based loop leak risk is engineered down, not denied: sealed loop, UQD self-sealing couplings, sensors and telemetry. Derivation public.
