Accelsius Makes NVIDIA GTC Debut with NeuCool® IR150, the Industry's First Integrated Rack for Two-Phase Liquid Cooling
MWN-AI** Summary
At the NVIDIA GTC 2026, Accelsius unveiled the NeuCool® IR150, a groundbreaking integrated rack designed for two-phase liquid cooling, capable of delivering an impressive 150kW cooling capacity. This innovative cooling solution combines a two-phase Coolant Distribution Unit (CDU), 42U of IT rack space, and built-in liquid and vapor manifolds into a single 800mm-wide enclosure, marking a significant advancement in data center infrastructure tailored for high-performance computing and AI applications.
The announcement comes at a critical juncture, as the demand for efficient cooling solutions rises in the face of increasing AI workloads that exceed traditional air cooling capabilities. The global liquid cooling market is anticipated to reach around $6 billion by 2026, driven by a shift towards liquid cooling technologies, as highlighted by NVIDIA's plans for its next-generation Vera Rubin platform, which is designed for liquid cooling using warm facility water.
Accelsius' NeuCool IR150 addresses this shift by offering a streamlined, plug-and-play solution that minimizes installation complexity and significantly reduces operational costs. Its design enhances reliability while confining potential failure domains to individual racks, thus promoting system uptime—an essential feature for mission-critical environments.
One of the standout features of the IR150 is its use of a non-conductive dielectric refrigerant, which eliminates the risks of leaks and corrosion common in traditional single-phase cooling systems. This two-phase approach not only enhances safety but also drastically lowers energy consumption and water use, supporting sustainability goals.
With its advanced design, the NeuCool IR150 positions Accelsius as a key player in the future of data center cooling and solidifies its role within NVIDIA's mission toward innovative infrastructure solutions.
MWN-AI** Analysis
Accelsius' launch of the NeuCool® IR150 at NVIDIA GTC 2026 marks a crucial milestone in the evolving landscape of data center infrastructure, especially in the context of rising AI workloads. The NeuCool IR150, being the first integrated rack for two-phase liquid cooling, offers a potent combination of efficiency and capacity—delivering 150kW of cooling in a compact 42U chassis.
As AI technology demands escalate, traditional air cooling solutions are becoming inadequate due to higher thermal densities. The establishment of a liquid cooling paradigm, as highlighted by NVIDIA’s push towards fully liquid-cooled systems, presents a significant market opportunity. Accelsius is strategically positioned to capitalize on this shift with its innovative, plug-and-play design that promises reduced deployment times and maintenance complexities.
Investors should note the growing liquid cooling market, projected to reach $6 billion by 2026, predominantly fueled by AI and high-performance computing. The NeuCool IR150 appears well-equipped to capture market share, particularly as it mitigates many risks associated with single-phase cooling, such as leaks and corrosion.
Another key feature of the IR150 is its operational efficiency; research indicates that two-phase cooling can lead to up to 90% reductions in cooling energy consumption. This not only aligns with sustainability goals but also translates into significant cost savings for operators—research shows potential OpEx savings of 35-44% over conventional systems.
Investors looking for robust growth in the tech sector may find potential in Accelsius. The company, being part of NVIDIA's Inception program, provides a competitive edge through its cutting-edge technology and strategic alignment with industry needs. As demand escalates for integrated cooling solutions, Accelsius' innovations could present attractive long-term investment opportunities in the evolving landscape of data centers.

Announcing at NVIDIA GTC 2026, the IR150 delivers 150kW of cooling capacity in a single, pre-integrated enclosure, reimagining infrastructure for the liquid cooling era.
Accelsius , the leader in two-phase, direct-to-chip liquid cooling technology for AI and high-performance computing, today 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 vapor manifolds in a single 800mm-wide enclosure, offering up to 150kW of capacity.
The announcement arrives at a pivotal moment for the data center industry. According to various sources, the global liquid cooling market is projected to be around $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 in 2026 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.
“The IR150 represents the next evolution of data center infrastructure,” said Josh Claman, CEO of Accelsius. “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. 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 percent and eliminate millions of gallons of annual water use compared to air-cooled alternatives, while independent analysis by Jacobs Engineering has demonstrated that Accelsius’ two-phase solutions deliver 35–44 percent annual OpEx savings and 8–17 percent five-year total cost of ownership savings over single-phase direct-to-chip systems.
Key benefits of the NeuCool IR150 include:
- Pre-integrated, plug-and-play design: CDU, 42U IT rack space, and liquid and manifolds ship as a single, factory-tested unit, reducing deployment time and on-site complexity.
- 150kW of two-phase cooling capacity: Supports current-generation GPUs including NVIDIA Blackwell and is designed with thermal headroom for next-generation platforms such as NVIDIA Vera Rubin.
- Single-rack failure domain: Modular architecture isolates cooling to each rack, simplifying maintenance and improving uptime for mission-critical environments.
- Warm-water compatible: ASHRAE W45 compatible, supporting facility water temperatures up to 45°C to enable more free-cooling days and reduce energy use.
- Zero water in the rack: Dielectric refrigerant minimizes leak risk to IT equipment, removes water treatment requirements, and supports sustainability goals.
- Hot-swappable serviceability: Pumps, power supply units, sensors, main control board, and LCD display can all be serviced without taking the rack offline.
