Accelsius

Accelsius LLC is an Austin, Texas thermal-management company founded in 2022 by Innventure to commercialize two-phase, direct-to-chip liquid cooling for AI, HPC and mission-critical data centers. Its NeuCool platform circulates a non-conductive dielectric refrigerant through cold plates mounted directly on CPUs and GPUs, removing heat by evaporation rather than by bringing water into the IT rack, and supports 4,500W+ per socket and rack densities up to 250kW. The product line includes the IR150 in-rack CDU, the MR250 medium-rack CDU, the NeuCool Thermal Simulation Rack and Liquid Simulation System used for evaluation and deployment planning, and multi-GPU cold plate assemblies, backed by professional services spanning system architecture, integration, deployment and maintenance. Accelsius is a hardware manufacturer, not a software or data company: it publishes no developer program, product API, SDK or machine-readable product specification. The only machine-readable interface on its public surface is the WordPress core REST API behind accelsius.com, which serves the company's own blog, news, white-paper, case-study, podcast and video content anonymously and read-only.

Accelsius publishes 10 APIs on the APIs.io network, including Resources Content API, News API, Pages API, and 7 more. Tagged areas include Company, Data Centers, Liquid Cooling, Thermal Management, and Direct-to-Chip Cooling.

Accelsius’ developer surface includes authentication, support, FAQ, engineering blog, code examples, and 24 more developer resources.
