Submer Group has launched Corenix, a dedicated modular data center infrastructure company that will build complete, factory-tested modules for neoclouds, hyperscalers, and AI operators based on Nvidia reference designs.

The company announced the launch this week. Corenix will design, build, integrate, and factory-test fully functional data center modules — covering IT, power, cooling, and networking — at production facilities before delivering and installing them at project sites.

Patrick Smets, CEO of Submer Group, tied the move directly to compute demand. "AI factories are driving unprecedented demand for new data center capacity, and the market needs a faster, more predictable way to build it," he said. "Corenix builds on Submer's history in modular data center delivery and the engineering, thermal, and infrastructure expertise we have developed solving high-density compute challenges for years. We are bringing that experience into a dedicated business built to deliver AI infrastructure at scale."

Who will run Corenix?

Martin Renkis has taken the CEO seat. He joins from Johnson Controls, where he served as executive director of data center infrastructure services. Before that, he founded Smartvue, an IoT hardware and software platform company that Johnson Controls acquired.

Renkis framed the new company's pitch around delivery certainty rather than technology alone. "Customers need clarity before they commit: what needs to be built, how it will be tested, who is accountable, and when it will become operational," he said. "That's the foundation I'm building Corenix on from day one."

He added: "Corenix puts a dated program and a go-live date on the table before a contract exists. One team stays accountable from factory integration and testing through on-site commissioning and operational readiness, with the same team offering the flexibility to support current and future accelerated computing systems."

What does the modular approach change?

Corenix shifts integration work from the construction site to the factory. Each module arrives at the project location already assembled and tested across four domains:

• IT
• Power
• Cooling
• Networking

That model targets the schedule risk that has become the central constraint for AI capacity buildouts. By fixing a go-live date before contract signature and holding a single team accountable through commissioning, Corenix aims to compress the path from order to operational capacity.

The decision to base platforms on Nvidia reference designs aligns the unit with the dominant accelerated-computing ecosystem, and Renkis said the same team structure will support both current and future generations of accelerated computing systems.

Where does Corenix fit in Submer's portfolio?

Submer, founded in 2015, started as an immersion cooling specialist. The Spanish company has since broadened into data center development and AI cloud services through two units: Rubix Data Centers and Radian Arc.

Corenix extends that expansion into full modular delivery. The new company draws on Submer's engineering and thermal experience with high-density compute, which it has accumulated since its founding, and packages it as standalone infrastructure offering for AI-scale deployments.

For operators racing to stand up AI capacity, the launch adds another factory-built option to a market where speed to power and predictable commissioning now decide competitive positioning.
