The Chemours Company and 2CRSi have signed a joint development agreement to accelerate the rollout of two-phase liquid cooling systems for high-density IT environments. The agreement follows the successful qualification of Chemoursโ Opteon two-phase immersion cooling fluid in 2CRSiโs current-generation servers.
With that milestone achieved, broader deployment is now being pursued. Both immersion and direct-to-chip cooling platforms will be developed further, particularly for AI workloads and next-generation chips, where thermal limits are being pushed rapidly.
A Technical Milestone Moves Into Commercial Focus
The qualification process was completed after compatibility testing confirmed that the fluid works with industry-standard IT components. As a result, commercial scaling is expected to advance more quickly. According to the companies, accelerated life cycle testing has already been conducted.
Chemours said its Opteon-based two-phase systems can reduce cooling energy consumption by up to 90% compared with conventional air cooling. In addition, power usage effectiveness can approach 1.0 under optimized conditions. Water consumption is also significantly reduced, and fluid recovery and reuse are supported through a circular model.
Because AI processors generate substantially higher heat loads, traditional air systems are increasingly being strained. Consequently, liquid cooling technologies are being evaluated across hyperscale and edge deployments. Two-phase systems, in particular, allow heat to be absorbed through phase change, which improves efficiency at high densities.
High-Density GPU Servers at the Center
The partnership builds on 2CRSiโs push into ultra-dense GPU configurations. Leveraging Chemoursโ next-generation fluids, 2CRSi has commercialized servers such as the Atlas 1.8GG 2PIC model. In that system, eight NVIDIA H200 GPUs are housed within a single 1U chassis. Such density has been enabled by two-phase cooling, which supports tighter packaging without thermal compromise.
Looking ahead, the companies plan to focus on advanced formats, including 15-kilowatt 1U servers powered by Nvidia GPUs. As AI inference expands and edge computing footprints grow, compact high-performance systems are increasingly being prioritized.
Nathan Blom, Vice President of Liquid Cooling at Chemours, said the company views two-phase cooling as a foundational technology for next-generation computing. He added that the collaboration is intended to help customers manage AI-driven demand while reducing energy and water consumption.
Alain Wilmouth, CEO of 2CRSi, said the agreement reflects the industryโs shift toward liquid cooling adoption. He noted that closer alignment between fluid innovation and server engineering will be required as GPU densities rise. Through the joint effort, energy-efficient systems for AI, edge computing, and advanced networking applications are expected to reach the market faster.
