Accelsius Launches NeuCool IR150 Integrated Rack with 150 kW Two-Phase Cooling
Accelsius unveiled the NeuCool IR150, an 800 mm-wide integrated rack combining a two-phase Coolant Distribution Unit and 42U of IT space to deliver up to 150 kW of liquid cooling for AI workloads. The plug-and-play design offers up to 90% cooling energy reduction, zero in-rack water and 35–44% annual OpEx savings.
1. Product Overview
Accelsius introduced the NeuCool IR150, an 800 mm-wide integrated rack combining a two-phase Coolant Distribution Unit, built-in liquid and vapor manifolds and 42U of IT space. The system delivers up to 150 kW of cooling capacity in a single enclosure, enabling plug-and-play deployment for high-density AI systems.
2. Market Context
The global liquid cooling market is projected to reach $6 billion in 2026 as AI workloads drive rack densities beyond air-cooling limits. NVIDIA’s forthcoming Vera Rubin supercomputer platform is engineered for full liquid cooling, signaling growing demand for purpose-built solutions.
3. Technical Benefits
The NeuCool IR150 allocates 200 mm to cooling infrastructure and 600 mm to servers, isolates failure domains per rack, and supports facility water temperatures up to 45 °C without in-rack water. Dielectric refrigerant use eliminates leak risk and removes water treatment requirements while enhancing sustainability.
4. Cost and Efficiency Impact
Two-phase cooling can cut cooling energy consumption by up to 90% and eliminate millions of annual water gallons compared with air-cooled systems. Independent engineering analysis shows 35–44% annual OpEx savings and 8–17% five-year total cost of ownership improvements over single-phase direct-to-chip systems.
