Accelsius is a U.S. liquid cooling company formed in 2022 by Innventure to commercialize two-phase direct-to-chip cooling. Its NeuCool system uses a dielectric refrigerant and, according to the company, cools more than 4,500 W per socket and racks up to 250 kW with no water use.
Accelsius was formed in 2022 by Innventure to develop and commercialize a cooling system based on years of thermal research. It builds two-phase direct-to-chip liquid cooling: a dielectric refrigerant boils on cold plates attached to CPUs and GPUs, carrying heat away without bringing water to the servers.

The main product is the NeuCool platform. Accelsius states that it supports more than 4,500 W per socket, rack densities up to 250 kW, and a thermal resistance of 0.020 C/W at a TDP above 700 W. The refrigerant is described as safe for electronics if it leaks.
