Vertiv has expanded its global liquid cooling portfolio with the launch of the Vertiv CoolCenter Immersion cooling system, a fully engineered solution designed to meet the extreme thermal requirements of AI and high-performance computing (HPC) environments.
The new immersion cooling system is now available across Europe, the Middle East, and Africa (EMEA), marking a strategic step in Vertiv’s efforts to support customers facing unprecedented rack densities and soaring heat loads driven by next-generation compute.
Immersion cooling works by submerging servers directly into a dielectric liquid – one that does not conduct electricity – allowing heat to be removed evenly and far more efficiently than traditional air-based methods. This approach has gained momentum as GPUs and accelerators push thermal envelopes beyond what legacy cooling designs can accommodate.
The Vertiv CoolCenter Immersion system offers a complete, integrated architecture engineered for high-density compute, with cooling capacities ranging from 25 kW to 240 kW per system. Designed for reliability, the solution incorporates internal or external liquid tanks, a coolant distribution unit (CDU), temperature and pressure sensors, variable-speed pumps, and fluid piping to ensure stable and precise thermal performance.
AI and HPC Deployments
“Immersion cooling is playing an increasingly important role as AI and HPC deployments push thermal limits far beyond what conventional systems can handle,” said Sam Bainborough, EMEA vice president of thermal business at Vertiv. “With the Vertiv CoolCenter Immersion, we’re applying decades of liquid-cooling expertise to deliver fully engineered systems that handle extreme heat densities safely and efficiently, giving operators a practical path to scale AI infrastructure without compromising reliability or serviceability.”
Redundancy features include dual power supplies and redundant pumps to maintain high cooling availability – an essential requirement for AI clusters that run continuously. The system also supports heat-reuse strategies, enabling operators to capture and redistribute waste heat for facility heating or other reuse initiatives, aligning with broader energy-efficiency and sustainability goals.
Operational management is streamlined through integrated monitoring sensors, a 9-inch touchscreen interface, and building management system (BMS) support, giving operators granular visibility over coolant temperature, flow rates, and overall system health.
Vertiv is pairing the new solution with its Liquid Cooling Services, offering design, installation, tuning, maintenance, and lifecycle optimisation to help enterprises adopt the right liquid-cooling architecture. The company now provides a full suite of options, from rear-door heat exchangers to direct-to-chip (D2C) cooling and immersion systems, reflecting increasing market demand for scalable, low-energy thermal solutions as AI workloads accelerate worldwide.
Executive Insights FAQ: Immersion Cooling for AI and HPC
Why is immersion cooling becoming essential for AI and HPC workloads?
AI and HPC clusters generate extremely high and sustained thermal loads that exceed the capabilities of air cooling. Immersion cooling removes heat directly at the source, enabling stable performance for dense GPU and accelerator systems.
How does immersion cooling impact data center energy efficiency?
Because immersion removes the need for large air-handling systems, it significantly lowers cooling energy consumption. Operators can achieve better PUE scores and reduce operational costs, especially in high-density environments.
Can immersion cooling help data centers scale AI infrastructure faster?
Yes. Immersion tanks allow operators to deploy higher compute densities per rack, reducing physical footprint constraints and simplifying thermal design. This accelerates the rollout of new AI/HPC clusters.
Does immersion cooling improve hardware reliability?
Immersion creates a controlled thermal environment with uniform heat dissipation, reducing thermal cycling stress on components. Many operators report longer hardware lifespan and fewer thermal-related failures.
How does immersion cooling support sustainability goals?
Immersion systems use less energy, enable heat reuse, and eliminate water consumption typical in evaporative cooling. This makes them attractive for operators targeting carbon reduction and long-term sustainability targets.
