What Chilldyne does
Chilldyne, Inc., founded in 2012 and headquartered in Carlsbad, California, designs and manufactures direct-to-chip (D2C) liquid cooling systems for high-density data centers serving AI, HPC, and cloud workloads. The company's core technical differentiator is a patented negative-pressure liquid cooling architecture, originally derived from rocket fuel pump designs, in which a vacuum pulls coolant through the cooling loop rather than pushing it under positive pressure, eliminating leak risk and allowing use of generic off-the-shelf connectors in place of expensive specialized fittings. Its product portfolio comprises the CF-CDU300 (300 kW) and CDU-1500 (1,500 kW) cooling distribution units, cold plates with turbulator technology (including 2 kW units for high-power AI processors), rack manifolds supporting more than 100 servers, the Cool-Flo Software control layer with DCIM/BMS integration, an ACQ automated coolant management system, and a plug-and-play Liquid Cooling Starter Kit for AI workloads.
The company's revenue model is hardware sales of CDU systems and associated components sold under multi-year enterprise contracts at custom-quoted pricing tied to cooling capacity and rack configuration. Go-to-market is channel-led: Chilldyne sells globally through Schneider Electric, to US government agencies via Carahsoft, and provides installation and field services in North America and Japan through Tekumo. End customers span AI/HPC operators, government and laboratory computing facilities, and colocation providers, with documented deployments including Sandia National Labs (Manzano supercomputer, leak-free since 2019), Cirrascale Cloud Services (1 MW of GPU cooling since 2014), the University of Texas at Austin TACC, and Penguin Computing.
On November 4, 2025, Daikin Applied Americas acquired Chilldyne for an undisclosed amount, integrating its negative-pressure liquid cooling technology into Daikin's broader data center thermal management portfolio alongside the August 2025 acquisition of DDC Solutions. The combined entity is positioned as a comprehensive cooling ecosystem for hyperscale and AI data center operators.
