Submer, one of the key leaders in the data center liquid cooling market, is now entering the data center design and construction space. It has announced that it will build its first data center, a 56 MW facility in Barcelona, which will serve as a first phase of more deployments across Europe.
According to a press release, Submer is leveraging its expertise to design and build next-generation liquid-cooled data centers, enabling seamless transitions from air to liquid cooling (Direct Liquid Cooling and Immersion Cooling). These sustainable, high-density facilities will support AI workloads.
“Our mission is to ensure businesses can scale AI workloads efficiently while reducing environmental impact,” says Submer’s Co-founder Daniel Pope. “The launch of our first 56MW facility in Barcelona is just the beginning—Submer is here to redefine how the world powers AI and build Datacenters That Make Sense.”
The Barcelona data center will showcase liquid cooling innovation, integrating a vertically optimized ecosystem that supports 150kW+ per rack or tank. By enabling higher compute densities with superior thermal management, the Barcelona facility will aim to pave the way for AI-enabled, carbon-conscious datacenters that are more efficient, scalable, and environmentally responsible.
As AI adoption accelerates, Submer is also launching a data center operator and AI-as-a-Service (AIaaS) business unit, providing vertically integrated infrastructure—from chip to AI applications—for enterprises seeking to scale efficiently and sustainably. Submer’s core cooling technologies business unit will remain unchanged, continuing its focus on driving the adoption of liquid cooling and accelerating AI-ready infrastructure.
