Accelsius has upgraded its Springdale laboratory in Austin to multi-megawatt power capability. The upgrade allows the company to test and validate its NeuCool two-phase liquid cooling technology on megawatt-class server racks, including powering a single rack at more than one megawatt. The firm also announced plans to expand the facility by an additional 18,000 square feet in January 2027 and introduced a new 375-kilowatt multi-rack cooling unit.

The expanded testing capabilities aim to meet the growing cooling demands of next-generation artificial intelligence hardware. In performance testing on B200 chips, the NeuCool system operated 9 degrees Celsius cooler than single-phase cooling under warm-water conditions. It also matched performance at 45 degrees Celsius using a 54 degrees Celsius inlet temperature, helping facilities maintain cooling efficiency.

Looking ahead, key catalysts to monitor include potential commercial deployment announcements, large purchase orders, or revenue directly linked to NeuCool system rollouts with major hyperscale data center operators.
