Johnson Controls announced a multi-million dollar strategic investment in Accelsius, a leader in two-phase, direct-to-chip liquid cooling technology for data centers. The investment was announced from Cork, Ireland, on October 6, 2025.

Investment Details and Technology Focus

The strategic investment targets Accelsius's specialized cooling technology, which utilizes “phase change” from liquid to vapor to remove heat, enabling more efficient heat extraction with reduced energy consumption. Two-phase solutions represent an advancement in data center cooling technology, addressing the critical need for efficient temperature management of computer chips that are foundational to the digital economy.

Austin Domenici, Vice President and General Manager of Johnson Controls Global Data Center Solutions, stated that with the sharp growth in AI, cooling innovation has become a frontline imperative to meet the increasing demands of high-density data centers. Johnson Controls aims to leverage its leading capabilities to drive the industry forward and unlock new levels of energy efficiency across the cooling chain.

Accelsius Technology and Cost Benefits

Josh Claman, CEO of Accelsius, explained that with power-dense AI workloads, data centers are moving to liquid cooling. Accelsius's two-phase, direct-to-chip (D2C) cooling solutions use non-conductive fluids in highly efficient loops to stay ahead of demanding power-dense AI and HPC workloads. The technology enables specific cost savings, including 35% operational expenditure (OpEx) savings over single-phase direct-to-chip solutions and 8-17% total cost of ownership savings.

Innventure, Inc. founded Accelsius and provides cooling solutions through its proprietary NeuCool platform, which offers thermal efficiencies via a safe, two-phase liquid cooling system that scales from single racks to entire data centers.

Industry Challenge and Energy Consumption

Cooling systems account for 30% to 40% of a data center's total energy consumption, making the deployment of energy- and water-efficient cooling solutions one of the industry's most pressing challenges. Cooling equipment is among the most critical components in a data center, required to efficiently and reliably maintain appropriate temperatures for computer chips.

The increasing demands of high-density data centers, particularly with the growth of AI, have intensified the need for advanced cooling innovations to address these energy consumption challenges.

Johnson Controls Existing Data Center Innovations

Johnson Controls has previously developed breakthrough innovations for data centers, including the YORK YVAM magnetic bearing chiller. This solution consumes 40% less power annually compared to other available solutions, while requiring zero on-site water consumption. This demonstrates how advanced technology can deliver sustainability and meaningful societal benefits.

The YORK YVAM technology was recently named to Fortune's “Change the World” list, and Johnson Controls was recognized as a data center leader, top innovator, and top leader by ABI Research. The company recently launched its Silent-Aire Coolant Distribution Unit (CDU) platform, offering scalable cooling capacities from 500kW to over 10MW in flexible designs that can meet the needs of any data center.

By adopting Johnson Controls' comprehensive thermal management solutions, owners, and operators can significantly improve total facility efficiency, reducing non-IT energy consumption by more than 50% in most North American data center hubs.
