Accelsius Expands Austin Lab to Multi-Megawatt Capacity for Two-Phase Liquid Cooling Testing of Next-Generation AI Racks
Accelsius, founded by Innventure (NASDAQ: INV), has upgraded its Springdale lab in Austin to multi-megawatt power for full-scale testing of its NeuCool two-phase, direct-to-chip liquid cooling platform. The upgrade lets the company validate cooling at megawatt-class rack densities that public GPU roadmaps point to in 2027, including 600kW racks and megawatt-class pod designs, with an 18,000-square-foot lease expansion opening in January 2027. Independent July benchmarks showed NeuCool delivering 9°C lower NVIDIA B200 junction temperatures than single-phase cooling in warm-water conditions, with each 1°C of warmer facility water worth roughly 4 percent in annual energy savings.
