As a leader in two-phase, direct-to-chip liquid cooling technology for data centres, Accelsius has successfully gained the interest of Johnson Controls, a leader in smart and sustainable buildings.
Although it has been involved with data centres for more than two decades, Johnson Controls has pivoted more into industry solutions in recent times. The company will now be supporting Accelsius in its two-phase solutions, which use ‘phase change’ from liquid to vapour to remove heat and enable more efficient heat extraction with reduced energy consumption.
“With the sharp growth in AI, cooling innovation has become a front-line imperative to meet the increasing demands of high-density data centres,” said Austin Domenici, vice president and general manager at Johnson Controls Global Data Center Solutions.
Cooling is currently one of the most mission critical aspects to a data centre and is responsible for helping to improve a facility’s efficiency and reliability. Despite these sustainability efforts, however, cooling systems still account for 30-40% of the total energy of a data centre. This remains one of the most significant challenges in the industry.
To find this balance, Johnson Controls has been pioneering a variety of breakthrough innovations for the data centre cooling sector. This includes its YORK YVAM magnetic bearing chiller – a solution that the company said consumes 40% less power per year with zero on-site water consumption. The technology was recently named to Fortune’s “Change the World” list and has been recognised as a data centre leader, top innovator and top leader by ABI Research.
The company has also launched its Silent-Aire Coolant Distribution Unit (CDU) platform that offers scalable cooling capacities to meet the needs of any data centre. With its technology, Johnson Controls said operators will be able to improve total facility efficiency and reduce non-IT energy consumption by more than 50% in most data centre hubs in North America.
“With power-dense AI workloads, data centres are moving to liquid cooling,” said 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. This technology enables 35% OpEx savings over single-phase direct-to-chip and 8–17% total cost of ownership savings.”
Domenici added: “Leveraging our leading capabilities, our mission is to drive the industry forward to unlock new levels of energy efficiency across the cooling chain.”
