Accelsius, Innventure unit, upgrades Austin lab to multi-megawatt liquid-cooling test capacity

Innventure, Inc.

Accelsius upgraded its Springdale lab in Austin, Texas to multi-megawatt power for two-phase direct-to-chip cooling testing at megawatt-class rack densities.
Plans to add 18,000 square feet to the Springdale lease in January 2027; CEO John Hewitt cited customer AI rack roadmaps showing 600kW racks in 2027.
Expanding NeuCool multi-rack family with a 375kW-capable unit, the next step beyond the MR250; more details promised in coming months.
July benchmarks: NeuCool ran NVIDIA B200 junction temps 9C lower than single-phase in warm water, matching single-phase at 45C facility water with inlet water up to 54C.
Each 1C rise in facility water temperature is worth ~4% in annual energy savings; several hyperscalers engaged via the NeuCool HyperStart program.
