Accelsius Gains Multi-Million Investment for Data Center Liquid Cooling

Accelsius, a specialist in advanced liquid cooling for data centers, has secured a multi-million-dollar strategic investment from Johnson Controls, a global leader in smart and sustainable building technologies. The funding marks a significant push to accelerate the adoption of next-generation cooling systems designed to handle the soaring power demands of AI and high-performance computing (HPC) environments.

Accelsius’ core innovation lies in its two-phase, direct-to-chip (D2C) liquid cooling technology. Unlike conventional air-based or single-phase liquid systems, two-phase cooling harnesses the physical process of phase change – from liquid to vapor – to dissipate heat directly at the chip level. This approach allows for more efficient heat transfer, drastically reducing the energy needed to maintain optimal chip temperatures. According to Accelsius, its system can deliver up to 35% operational savings over single-phase D2C cooling and reduce total cost of ownership by as much as 17%, making it a promising solution for hyperscale and AI-driven data centers.

“Power-dense AI workloads are pushing traditional cooling methods to their limits,” said Josh Claman, CEO of Accelsius.Cooling represents one of the largest energy drains in data center operations, typically accounting for 30% to 40% of total power consumption. As global data center capacity expands to meet the explosion of AI workloads, sustainable thermal management has become a top engineering and environmental challenge.

“Power-dense AI workloads are pushing traditional cooling methods to their limits,” said Josh Claman, CEO of Accelsius. “Our non-conductive, closed-loop two-phase technology ensures performance scalability while improving both efficiency and sustainability.”

Sharp Growth in AI

While the investment positions Accelsius as a key innovator in the thermal technology space, Johnson Controls plays a strategic supporting role – leveraging its global reach, engineering expertise, and portfolio of cooling innovations. The company, known for products such as the YORK YVAM magnetic bearing chiller and Silent-Aire Coolant Distribution Unit platform, has been expanding its focus on energy-efficient infrastructure for mission-critical environments.

Austin Domenici, vice president and general manager of Johnson Controls Global Data Center Solutions, said the collaboration aligns with the company’s broader mission: “With the sharp growth in AI, cooling innovation has become a front-line imperative. Our partnership with Accelsius underscores our commitment to driving the industry forward and achieving new levels of energy efficiency across the entire cooling chain.”

As AI and HPC adoption accelerate worldwide, this partnership illustrates how data center infrastructure is evolving beyond performance metrics toward long-term sustainability and operational resilience – a critical shift for a sector projected to consume “nearly 10% of global electricity by 2030.”
