Accelsius Upgrades Austin Facility to Multi-Megawatt Power for AI Cooling
Accelsius, a liquid cooling company founded by Innventure, Inc. (NASDAQ:INV), has upgraded its Springdale testing facility in Austin, Texas, to multi-megawatt power capacity. The upgrade enables the facility to validate two-phase direct-to-chip cooling systems under the high rack power densities and elevated water temperatures demanded by upcoming artificial intelligence infrastructure. The company also plans to expand its lease footprint at the site by an additional 18,000 square feet in January 2027.
As artificial intelligence hardware demands increase, GPU roadmaps project power requirements to reach 600 kilowatts per rack in 2027 alongside megawatt-class designs. The upgraded Austin lab allows full system testing from cold plates to coolant distribution units under high-load conditions. Situated in Central Texas where summer temperatures regularly pass 100 degrees Fahrenheit, the lab serves as a proving ground for warm-water cooling performance in hot environments.
Accelsius is exhibiting its NeuCool cooling platform at the Open Compute Project Global Summit in San Jose from October 12 to 15, 2026. The company is also adding a 375-kilowatt-capable unit to its NeuCool multi-rack product line and continuing engagement with hyperscale data center operators through its HyperStart program.
