In-rack CDU System Introduced by Accelsius with 150kW Capacity

Accelsius has launched a new cooling distribution for a two-phase liquid cooling system. The company introduced the NeuCool IR150. This is described as a fully integrated rack-level cooling solution that connects a two-phase coolant distribution unit, 42U of IT rack space, and built-in liquid and vapor manifolds in a single 800mm-wide enclosure, providing up to 150kW of capacity.

The IR150 is integrating a two-phase CDU directly into the IT enclosure, allocating 200mm to cooling infrastructure with 600mm to serve space. The single-phase cooling systems mainly rely on water being circulated to heat plates. This plate is responsible for removing extra heat generated in the system, called IT gear. It uses a non-conductive dielectric refrigerant.

According to Precedence Research, the data center CDU market size accounted for USD 2.40 billion in 2025 and is predicted to increase from USD 2.88 billion in 2026 to approximately USD 14.61 billion by 2035, expanding at a CAGR of 19.80% from 2026 to 2035 due to the rapid shift towards liquid cooling, advancement like IoT-enabled intelligent CDUs with AI/ML based fault detection and growing demand for modular CPUs to manage dense hardware.

Mr. Josh Claman, CEO of Accelsius, said, “The IR150 represents the next evolution of data center 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. 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.”

A recent report by Precedence Research highlights that the data center CDU market is benefiting from increasing costs and ESG commitments, rapid expansion of hyperscale facilities, and the growing demand for edge data centers.
