Accelsius Closes $65 Million Series B Funding Led by Johnson Controls; Legrand Joining Round to Scale Liquid Cooling for Gigawatt-Class AI Factories
Strategic investment fuels Accelsius’ rapid growth and the deployment of proprietary high-cooling capacity reference designs, backed by Johnson Controls and Legrand to meet the intense thermal demands of the AI era.
AUSTIN, Texas–(BUSINESS WIRE)–Accelsius, the leader in two-phase, direct-to-chip liquid cooling for AI and high-performance computing, today announced the closing of its Series B funding round, raising $65 million. The round was led by Johnson Controls (JCI), the global leader for smart, healthy and sustainable buildings, with strategic investment from Legrand, a global specialist in electrical and digital building infrastructures.
This investment underscores the intense demand for robust liquid cooling solutions capable of managing the extreme thermal densities of next-generation high-performance compute and AI chips.
The investment by Johnson Controls and Legrand provides Accelsius with a unique strategic advantage. Johnson Controls, which previously announced its investment in Accelsius, has deep expertise in thermal management and has pioneered several innovations for data centers, including its YORK® YVAM chiller, technology that improves total facility efficiency. Legrand brings a vast portfolio of data center infrastructure solutions, including power distribution, rack infrastructure and connectivity.
Josh Claman, Chief Executive Officer of Accelsius, said:
We are witnessing the dawn of a new era in digital infrastructure, where the ‘AI Factory’ replaces the traditional data center.
”To meet the demands of this age, we must build responsibly and efficiently at a gigawatt scale. The investment from industrial giants like Johnson Controls and Legrand is about more than just capital; it signals strong potential and accelerating adoption of two-phase approaches that deliver high-performing AI solutions with unmatched efficiency.”
Austin Domenici, Vice President and General Manager, Global Data Center Solutions at Johnson Controls, said:
AI-scale computing is rewriting the thermal playbook.
”Our investment in Accelsius aligns with Johnson Controls’ strategy and commitment to deliver advanced, high-efficiency cooling solutions that enable operators to deliver AI solutions rapidly, now and in the future,”
Today’s IT racks already consume up to 130 kilowatts of power. As data centers pivot from traditional air cooling, which consumes up to 40 percent of a data center’s power use, to liquid cooling to handle the massive heat generation of modern GPUs, Accelsius, as the pioneer of two-phase liquid cooling, is positioned to lead the transition with its proprietary NeuCool® technology. Its two-phase solutions use non-conductive fluids in highly efficient loops – enabling 35% OpEx savings over single-phase direct-to-chip and 8–17% total cost of ownership savings.
The Series B capital will accelerate Accelsius’ rapid expansion of its Austin production facility, speed global expansion, and support the rollout of its proprietary, two-phase liquid cooling solutions.
Accelsius, a member of NVIDIA’s Inception program, is building new thermal reference designs that allow for significantly greater cooling capacity than previously considered possible, enabling operators to deploy high-performance GPUs at density without compromising efficiency or sustainability.
This announcement follows a period of rapid momentum for Accelsius, marked by significant customer acquisition, including the recent agreement to deploy NeuCool® technology across a 300 MW campus for DarkNX in Ontario.
Brian DiBella, President and CEO of Legrand, North and Central America, said:
The data center industry is facing a critical inflection point where thermal management is no longer just a facility concern, but a strategic imperative for IT performance,
“Accelsius’ two-phase, direct-to-chip technology offers a clear path to supporting the heat densities of AI workloads while improving energy efficiency. We are proud to invest in a company that is not only innovating but doing so with a focus on sustainability and operational practicality.”
