Accelsius has introduced the NeuCool IR150, the industry’s first fully integrated rack-level cooling solution that combines a two-phase Coolant Distribution Unit (CDU), 42U of IT rack space, and built-in liquid and vapour manifolds in a single 800mm-wide enclosure.
The plug and play solution provides up to 150kW of capacity.
The global liquid cooling market is projected to reach $6 billion in 2026, driven by AI workloads that generate rack densities that air cooling can no longer manage.
At the same time, NVIDIA CEO Jensen Huang revealed earlier this year that the company’s next-generation Vera Rubin platform, expected in the second half of 2026, is designed to be cooled entirely via liquid cooling, using warm overhead facility water at temperatures up to 45°C.
As the industry’s leading chipmaker signals a future built on liquid cooling, Accelsius, an NVIDIA Inception program member, is delivering the infrastructure to make that future a reality today.
Reimagined for the mission-critical liquid cooling era, the IR150 integrates a two-phase CDU directly into the IT enclosure, allocating 200mm to cooling infrastructure and 600mm to server space.
The result is a true plug-and-play solution for high-density, two-phase-enabled deployments.
The system dramatically simplifies installation, reduces technology cooling system (TCS) complexity and cost, and confines failure domains to a single rack.
Accelsius CEO, Josh Claman, said the IR150 represents the next evolution of data centre infrastructure.
“When the world’s leading chipmaker designs its next-generation AI supercomputers to run on liquid cooling, the industry needs purpose-built infrastructure to deliver it,” Claman said.
“The IR150 does exactly that, a single, integrated rack that arrives ready to cool the most demanding AI workloads, with minimal chiller infrastructure, no water treatment, and no compromise on reliability.”
Traditional single-phase liquid cooling systems rely on treated water circulated directly to the chip, introducing leak risk, corrosion concerns, and continuous water-quality maintenance.
In contrast, Accelsius’ two-phase approach uses a non-conductive dielectric refrigerant with an A1 safety rating and low global warming potential.
No water enters the IT rack, meaning leak events pose minimal risk to GPUs or server electronics.
Industry studies have shown that two-phase cooling systems can reduce cooling energy consumption by up to 90 per cent and eliminate millions of gallons of annual water use compared to air-cooled alternatives.
Independent analysis by Jacobs Engineering has demonstrated that Accelsius’ two-phase solutions deliver 35–44 per cent annual OpEx savings and 8–17 per cent five-year total cost of ownership savings over single-phase direct-to-chip systems.
