Submer Group has launched Corenix, a modular data centre infrastructure company serving neoclouds, hyperscalers and AI operators, and appointed former Johnson Controls executive Martin Renkis as CEO. Headquartered in Houston, Corenix designs, integrates and factory tests complete data centre modules covering IT, power, cooling and networking before delivering them to customer sites. It then manages installation, connection to site infrastructure, acceptance testing, commissioning and operational readiness. Each platform is based on an Nvidia reference design and engineered to the client's requirements.
The launch is the latest step in Submer's move beyond its immersion cooling roots after expanding into data centre design and construction. The group has deployed more than 500MW of liquid-cooled infrastructure and holds over 8GW of powered land across the Americas, EMEA and APAC. It pointed to a campus with hundreds of megawatts of capacity delivered as a fully modular buildout in nine months from order to delivery. Corenix sits alongside two other Submer Group companies: Rubix Data Centers, which develops and operates AI data centre campuses, and Radian Arc, which provides GPU-as-a-Service and AI-as-a-Service.
Patrick Smets, CEO of Submer Group, said AI factories were driving unprecedented demand for new capacity and that the market needs "a faster, more predictable way to build it". Renkis said customers want clarity on scope, testing and accountability before committing, and that Corenix will put "a go-live date on the table before a contract exists", with a single team responsible from factory integration through to on-site commissioning. At Johnson Controls, Renkis was executive director of data centre infrastructure services, developing AI infrastructure offerings spanning power, cooling, heat recovery, operations and financing.
What remains unknown is the financial structure of the new entity, the size of its initial order book, and whether the nine-month campus delivery cited by Submer Group is repeatable across different regulatory and grid environments. The source also does not specify which Nvidia reference designs Corenix will support first or how the modular model will handle successive generations of high-density hardware in practice.
