Liquid-cooled racks
compute and cooling, integrated at the factory
Racks are cabled, fitted with manifolds, leak-tested and burned in at the factory; on site they only need to be placed and connected to power and coolant.
2optionsliquid cooling: cold plate and immersion
≥ 2000kgMGX rack rated static load
34–44°Csecondary loop (93–111 °F), dry-cooler ready
1400kWmax room-level CDU capacity
150kWmax heat rejection per immersion tank
AI Rack Hub MGX 1.1 Rack
One rack, three models
Built to the NVIDIA MGX 1.1 rack geometry. Sites without liquid cooling can start with the air-cooled model and later convert the same rack to cold-plate cooling without changing layout, power or cabling.
Cooling pathFull-height manifolds on both sides, connected to the facility water loop
Supported nodesRTX PRO 5500 cold-plate modules, RTX PRO 6000 SE cold-plate nodes, DGX B300 (expansion bay)
Best forMainly inference and RAG, with fine-tuning and training
Cooling pathFull-height manifolds on both sides, loop closed by a liquid-to-air CDU beside the rack
Supported nodesDGX B300, RTX PRO 6000 SE cold-plate nodes
Best forTraining and high-throughput inference in rooms without facility water
Cooling pathFront-to-back airflow, vertical PDUs on both sides
Supported nodesRTX PRO 5500, RTX PRO 6000 SE air-cooled nodes, DGX Station, DGX B300 air-cooled (expansion bay)
Best forEdge inference, rendering, development; can move to liquid later

Cold-plate cooling equipment
The coolant distribution unit (CDU) is the heart of a cold-plate system, with variable-speed pumps and hot-swappable key components.
| Type | Rated cooling capacity | Secondary flow | Dimensions (W × D × H) | Best for |
|---|---|---|---|---|
| Rack-mount CDU | 15 / 20 / 30 / 40 kW | 2.4–4.5 m³/h | 436 × 850–880 × 175 mm | One or a few racks |
| In-row CDU | 120 / 200 / 400 / 600 / 900 kW | 15–110 m³/h | 600–1000 × 1200 × 2200 mm | Installed in the row, one per row |
| Room-level CDU | 300 / 500 / 1400 kW | 36–105 m³/h | 600–900 × 1200 × 2200 mm | Connects to the facility loop, with built-in automatic make-up |
| Manifolds | 30 × 30 or 40 × 40 mm, 1–30 branches, 304 stainless steel; flow variation under 4%; 100% helium leak-tested | |||
| Secondary loop network | DN25–DN150 prefabricated 304 stainless piping; flow variation under 10%; leak location detection | |||
Immersion tanks
Standalone tanks offer more capacity with an external CDU; all-in-one tanks build the heat exchanger and pump into the tank and are plug-and-play.
