Johnson Controls has confirmed a multi-million-dollar investment in Accelsius, a leader in two-phase direct-to-chip liquid cooling technology for data centers.
Two-phase solutions use ‘phase change’ from liquid to vapor to remove heat, enabling more efficient heat extraction with reduced energy consumption.
Cooling is among the most critical equipment in a data center, efficiently and reliably keeping the chips at the right temperature that are foundational to the digital economy and our everyday lives.
However, with cooling systems accounting for 30% to 40% of a data center’s total energy, deploying energy- and water-efficient cooling solutions is one of the industry’s most pressing challenges.
“With the sharp growth in AI, cooling innovation has become a front-line imperative to meet the increasing demands of high-density data centers,” says Austin Domenici, vice president and general manager, Johnson Controls Global Data Center Solutions. “Leveraging our leading capabilities, our mission is to drive the industry forward to unlock new levels of energy efficiency across the cooling chain.”
“With power-dense AI workloads, data centers are moving to liquid cooling,” adds Josh Claman, CEO of Accelsius. “Our two-phase, direct-to-chip (D2C) cooling solutions use non-conductive fluids in highly efficient loops to stay ahead of the demanding power-dense AI and HPC workloads.
"The technology enables 35 per cent OpEx savings over single-phase direct-to-chip and 8–17% total cost of ownership savings.”
Johnson Controls has already pioneered a number of breakthrough innovations for data centers including its YORK® YVAM magnetic bearing chiller – a solution that consumes 40 per cent less power annually as other available solutions with zero on-site water consumption, demonstrating how advanced technology can deliver sustainability and meaningful societal benefits.
The technology was recently named to Fortune’s “Change the World” list, and recognized as a data center leader, top innovator and top leader by ABI Research.
In addition, the company recently launched its Silent-Aire Coolant Distribution Unit (CDU) platform offering a wide range of scalable cooling capacities from 500kW to over 10MW in flexible designs that can meet the needs of any data center.
