Accelsius Launches NeuCool® MR250 at OCP Global Summit
Accelsius, a prominent name in liquid cooling technology, has officially launched the NeuCool® MR250, a cutting-edge coolant distribution unit (CDU) engineered for high-performance computing (HPC) and artificial intelligence (AI) applications. The MR250 made its public debut at the Open Compute Project (OCP) Global Summit, held from October 13 to 16 in San Jose. This innovative solution is part of a broader strategy by Accelsius to enhance the scalability of two-phase, direct-to-chip (2P D2C) cooling systems, addressing the growing demands of modern data centers.
At the heart of the MR250’s capabilities is its impressive 250 kW liquid cooling capacity, which can be configured in flexible setups (either a single 250 kW or two 125 kW per rack). This product marks the first in a series of NeuCool solutions aimed at providing increasingly powerful cooling options, with plans for even higher-capacity systems expected to be unveiled in 2026.
Enhanced Efficiency and Sustainability
According to Josh Claman, CEO of Accelsius, the MR250 represents a significant advancement in liquid cooling technology. He emphasized that the new system transforms two-phase, direct-to-chip solutions from mere concepts into reliable, scalable systems that meet the rigorous requirements of contemporary data centers. Claman stated that with the MR250, operators can confidently deploy their infrastructure while minimizing risks, maintenance needs, and overall costs.
One of the key advantages of the MR250 is its ability to operate with refrigerant-based cooling, which reduces the frequent water treatment and monitoring associated with traditional single-phase systems. This transition not only lowers the risk of leaks but also simplifies operational management, enhancing the protection of critical IT assets and ensuring greater reliability in essential environments. Moreover, the MR250 supports higher facility water temperatures of up to 45 degrees Celsius, which facilitates more efficient cooling days and reduces energy consumption.
Scalability and Future Outlook
The production of the MR250 is taking place at Accelsius’ newly expanded facility in Austin, which has increased its manufacturing capacity by an impressive 500%. This expansion will allow for scalable production, with additional support for high-volume orders expected as demand grows. Initial deployments of the MR250 began in late Q3 2025, with wider availability anticipated as the year progresses into 2026.
As part of its presence at the OCP Global Summit, Accelsius is participating in a series of sessions focused on technical advancements in cooling technology. These include discussions on the application of two-phase micropillar evaporators for next-generation GPU servers and a comparative analysis of total cost of ownership between single-phase and two-phase cooling systems.
For those interested in exploring the NeuCool® MR250 further, Accelsius invites attendees to visit Booth B43 at the summit or reach out via their official website for more information about their innovative cooling solutions. The company’s commitment to advancing cooling technology positions it as a key player in the evolution of data center operations and sustainability goals within the industry.
