Johnson Controls (NYSE: JCI) announced a multi-million-dollar investment in Accelsius, a company specializing in two-phase, direct-to-chip liquid cooling technology for data centers. The system uses liquid-to-vapor phase change to efficiently remove heat, cutting energy use by up to 35% in operational costs and 8–17% in total ownership costs compared to single-phase systems.

The partnership aims to meet the surging cooling demands from AI-driven, high-density data centers, an area where cooling can consume up to 40% of total energy. Johnson Controls will integrate this technology into its advanced thermal management portfolio, which already includes the YORK® YVAM magnetic bearing chiller and Silent-Aire CDU platform, enabling over 50% non-IT energy reduction in some data centers.

Both companies said the deal underscores their shared goal of improving energy efficiency and sustainability in data center infrastructure.
