What the Flexnode modular data center platform offers

Flexnode (flexnode.io) describes itself as a modular AI infrastructure platform. It offers standardized prefabricated modular data centers, the NX series, under what it calls “one contract, from design to operation.” In practice, that means one company holds data center design, modular construction, delivery and operations, rather than a buyer coordinating separate engineering, manufacturing and construction contracts. Its markets include AI and cloud compute providers, sovereign, government and research users, enterprise and industrial edge compute, and capital and infrastructure partners.

Note the name: flexnode.com is an unrelated software consultancy. The data center company is at flexnode.io.

The NX series

• NX-1: 1–4.5 MW
• NX-2: 4.5–9 MW
• NX-3: 9–13.5 MW
• NX-4: 13.5–18 MW

Flexnode describes the units as standardized subassemblies with a persistent shell, rather than ISO shipping containers, and states that its campuses can scale beyond 100 MW. On cooling, the site describes its designs as “closed-loop and water-free,” with high-density, liquid cooled modular designs. The specific liquid method, such as direct-to-chip or immersion, is not stated in the material we reviewed.

On commercial terms, Flexnode states that capacity can be owned or leased, and that partners can develop, own and monetize sites.

Eaton, power infrastructure and AI factories

On January 28, 2026, Eaton announced that it led Flexnode’s Series A and formed a strategic collaboration. The release was titled “Eaton expands modular data center offering for rapid deployment of AI factories from grid to chip.” The companies plan to integrate Eaton power infrastructure and 800 VDC technology into the Flexnode NX Compute Module for high power density data halls of 3.5 to 35 MW, with multiple halls per site. The amount of the Series A was not disclosed in the sources we reviewed.

Eaton later named Flexnode modules as one of the building blocks of its Beam Rubin DSX platform, alongside Fibrebond enclosures and NordicEPOD skids, announced in March 2026. Flexnode also reports that it was listed among prefabricated modular data center vendors in Gartner’s 2026 Hype Cycle.

How the delivery models compare

Flexnode’s units are sized in megawatt bands from 1 MW to 18 MW and sold as part of a turnkey design-to-operation contract. QIT works in smaller GPU container blocks scoped to a specific site. The table below compares published Flexnode information with QIT’s approach.

Ask each supplier to state whether a megawatt figure refers to IT load or total facility power. The answer changes how many units a site can support.

Both companies use liquid cooled designs for high density AI and high performance computing workloads. The difference is mainly in scale, contract scope and where the timeline starts: Flexnode offers a scalable platform across a wide MW range, while QIT focuses on phased GPU containers on existing powered land.

High density AI infrastructure: large modules versus smaller blocks

Unit size shapes the whole project. A multi-megawatt prefabricated module concentrates power infrastructure, cooling technologies and compute infrastructure into fewer, larger deliveries. That can suit a site with substantial power available on day one, steady demand and a single long-term operator.

Smaller GPU container blocks suit a different situation: a powered property where usable capacity arrives in stages, or where the GPU platform for the second phase has not been chosen yet. Each block can be scoped against the power, liquid cooling solutions and hardware available at the time, which helps when the next generation of high density compute changes rack power and coolant requirements between phases.

Neither approach is better in general. The right choice depends on how much power you can use, when you can use it, and how much of the design-to-operation scope you want a single supplier to hold. An illustrative example: a site with 3 MW available now and a further 4 MW in 18 months may favor phased blocks, while a site with 15 MW energized at once may favor a larger unit.

When each option fits

Flexnode may fit when you are planning a large AI data center campus, want multi-megawatt units with a persistent shell, value a single design-to-operation contract, or plan to use Eaton’s power infrastructure and an 800 VDC architecture. Its range extends well above QIT’s 5–10 MW site focus.

QIT may fit when you have an existing powered property in Texas, need liquid-cooled GPU capacity in roughly 1 MW steps, and want to phase deployment as power and hardware become available. Smaller blocks can make it easier to match capacity to the power you can use today, and to plan maintenance and upgrades one block at a time.

For other options, see the modular data center companies guide or compare Armada and Mod42.

Questions to ask any modular vendor

• Is the quoted megawatt figure IT load or total facility load?
• Which parts of the power infrastructure, from utility interconnection to the rack, are inside the contract?
• What cooling method serves the GPUs, and does “water-free” cover heat rejection at your site’s design temperature?
• Will you own the modules, lease capacity or buy a service?
• Who operates the site after commissioning, and on what terms?
• What event starts the delivery schedule, and which dependencies can move it?
• How is full-system acceptance defined?
