Submer: UK Expansion and Partnered Push for Liquid Cooling

Submer has announced a new UK partnership aimed at accelerating the adoption of liquid cooling technologies as AI and high-performance computing workloads increase data centre power density.

The company, which provides end-to-end AI infrastructure services, has signed an agreement with Boston, a provider of high-performance computing and AI infrastructure solutions.

The collaboration will expand access to Submer’s liquid cooling technologies in the UK alongside design, deployment and lifecycle support services.

Submer’s platform spans liquid cooling systems, monitoring software, data centre design and build services as well as GPU cloud capabilities.

The company says its integrated approach gives organisations a single partner to support the deployment and operation of AI-ready infrastructure.

Liquid cooling and high-density compute

Demand for high-density infrastructure is rising as AI training and inference workloads push traditional data centre cooling and power systems to their limits.

Manpreet Bath, Vice President for Commercial Engagement at Submer, says: “The UK is one of Europe’s most strategically important AI infrastructure markets. Strengthening our local partnerships ensures organisations can deploy energy-efficient, high-density environments while maintaining control over where their data is processed and governed.”

The UK data centre sector has expanded rapidly in recent years, with facilities now designated as Critical National Infrastructure. Capacity is expected to nearly double by 2028, driven by demand from industries including financial services, healthcare and higher education.

According to Oxford Economics, the UK – Europe’s largest data centre market – has attracted more than £40bn (US$53.35bn) in investment since 2023.

Partnership with Boston Ltd.

Through the new agreement, Boston will combine its experience in system integration with Submer’s cooling technologies to support organisations deploying high-performance compute infrastructure.

Manoj Nayee, Managing Director at Boston Limited, says: “AI and HPC workloads are driving a transformation in infrastructure design throughout the UK.

“With increasing power densities and heightened performance demands, conventional cooling methods can no longer keep pace. Liquid cooling is swiftly becoming a necessity for providing efficient, scalable, and sustainable high-performance environments. 

“By leveraging Boston’s extensive experience in AI and HPC system integration alongside Submer’s advanced cooling technology, we empower organisations to implement sovereign, AI-ready infrastructure that satisfies the UK’s growing needs while minimising energy consumption.”

Supporting sovereign infrastructure

Submer says the expansion also aligns with the UK Government’s focus on sovereign digital infrastructure, ensuring sensitive data generated within the country can be processed and governed domestically.

Liquid cooling systems can support higher rack densities while lowering overall energy consumption compared with conventional air cooling. Submer’s systems are also designed for zero direct water consumption, helping operators reduce operational costs and meet sustainability targets.

Alongside the Boston partnership, Submer is expanding its UK presence through additional hiring in technical and commercial roles to support customer engagement and infrastructure deployments.
