Accelsius, the leader in two-phase, direct-to-chip liquid cooling technology for AI and high-performance computing, today announced the general availability of 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.

Reimagined from the ground up for the liquid cooling era, the IR150 is a true plug-and-play system designed to move through established IT infrastructure channels, making two-phase liquid cooling accessible not just to hyperscalers but to enterprises and smaller operators for the first time. Its fully integrated form factor is perfect for edge deployments and the small language model workloads that will proliferate across the market as AI matures. The company also unveiled the NeuCool HyperStart program, a new initiative created to support hyperscale operators, neocloud providers, and key partners in validating two-phase direct-to-chip liquid cooling solutions and accelerating their readiness for high-density, large-scale deployments.

The announcements come at a pivotal moment for the data center industry. Hyperscale and neocloud operators are moving at unprecedented speed to bring gigawatt-class AI facilities online, and with that velocity has come increasing public scrutiny of power and water use in host communities. Billions of dollars in planned data center projects have already been delayed or blocked amid concerns about strain on local resources. Accelsius believes the industry can, and should, continue to move quickly—but responsible planning for more efficient AI factories also requires a hard look at waterless and more energy-efficient liquid cooling architectures from day one.
