On August 10, Chemours (NYSE:CC) launched two new refrigerants, Opteon ZE and Opteon 515B, built specifically for stationary chillers that cool data centers, commercial buildings, and other facilities that cannot afford downtime. The announcement lands as data center operators everywhere are scrambling to keep pace with the heat that AI workloads generate, and Chemours is betting its chemistry can be part of the answer. Chemours designed these products around a specific problem: AI infrastructure is pushing heat loads and uptime requirements past what older cooling systems were built for.
Joseph Martinko, President of Thermal & Specialized Solutions at Chemours, said the company is expanding the choices available to chiller manufacturers and operators as they build and maintain the systems powering data centers and other mission-critical environments. That framing matters because it puts Chemours squarely inside the AI infrastructure buildout rather than on its periphery, and the company describes this as part of a broader push into higher-value, high-growth cooling applications. The two products are designed to work together rather than compete for the same customer.
Opteon ZE, the R-1234ze(E) formulation, is an HFO-based refrigerant with a GWP of approximately 1 and zero ozone depletion potential, aimed at air- and water-cooled chillers, commercial air conditioning, heat pumps, and data center cooling specifically. It also offers high energy efficiency and works with commonly used POE lubricants, which matters for equipment makers who do not want to redesign their systems from scratch. Opteon 515B is a blend of roughly 91.1% R-1234ze(E) and 8.9% R-227ea, with a GWP near 293, pitched at operators running conventional chillers who want an easier path away from higher-GWP refrigerants without a full system overhaul.
Having both a near-zero-GWP option and a lower-friction transitional option lets Chemours sell into new builds and legacy fleets at the same time. The launch is not without caveats. Opteon ZE carries an ASHRAE A2L classification, meaning it is mildly flammable, while Opteon 515B carries the non-flammable A1 rating.
That difference alone could steer certain customers toward one product over the other depending on local codes and installation requirements. Chemours also said the products are available now only in strategic countries, with broader availability to follow demand, so the near-term revenue contribution is likely to build gradually rather than arrive all at once. The company further noted it is confident in its ability to manufacture and sell these refrigerants while respecting applicable intellectual property rights, a line that points to how contested the chemistry around low-GWP refrigerants has become as multiple players chase the same regulatory shift.
Hedge fund interest in Chemours ticked higher, with 40 funds holding a position in the most recent quarter compared to 38 in the prior quarter. The stock trades at a forward P/E of 7.36 as of September 2, a multiple that prices in very little growth or optimism. Short interest sits at 12.61% of float, a level that reflects a real bear camp rather than routine hedging.
