Submer Tech Stack

Immersion cooling and electrical infrastructure for hyperscale datacenters

IT Services and IT Consulting Rubí, Barcelona 51–200 employees Founded 2015 Privately Held

Submer designs and deploys immersion-cooling systems and modular power infrastructure for hyperscale and HPC environments. The stack—BMS, SCADA, PLC/HMI controls, plus CAD/simulation tools (ANSYS, SolidWorks, COMSOL)—reflects a hardware-heavy, systems-integration business. Active adoption of Intune and Azure Entra ID signals infrastructure modernization, while the project slate (100 MW AI factory in Georgia, modular power pods, greenfield deployments) shows the company scaling from engineering R&D into manufacturing and field delivery.

About Submer

Submer develops immersion-cooling and modular electrical-infrastructure solutions for next-generation datacenters, hyperscalers, and energy-intensive computing environments. Founded in 2015 and headquartered in Barcelona, the company addresses thermal and power-delivery challenges in high-density deployments—particularly for AI factories, HPC clusters, and colocation facilities. Their product portfolio spans cooling systems, modular power pods, and control/automation platforms. The hiring mix (engineering-dominant, with sales and product roles) and active project focus reflect a transition from pure technology development toward commercialization and field deployment across North America, the Middle East, and Asia-Pacific.
