Chemical firm Chemours has launched two new refrigerants for data center chillers.

NYSE-listed Chemours Company this week announced the launch of Opteon ZE (R-1234ze(E)) and Opteon 515B (R-515B) for stationary chiller applications.

The company said the new refrigerants provide customers with additional low-global warming potential (GWP) refrigerant options for large-scale cooling applications, including rapidly growing AI and data center infrastructure.

“AI is reshaping the demands placed on cooling infrastructure, and customers need solutions that can keep pace without compromising efficiency, reliability, or long-term regulatory readiness,” said Joseph Martinko, president, thermal and specialized solutions at Chemours. “With Opteon ZE and Opteon 515B, Chemours is expanding the choices available to chiller OEMs and operators as they build and maintain the critical systems powering data centers, commercial buildings, and other mission-critical environments, while further strengthening our position in attractive, high-growth cooling applications.”

Opteon ZE (R-1234ze(E)) is a hydrofluoroolefin (HFO) based refrigerant the company said is well suited for air- and water-cooled chillers, commercial air conditioning, heat pumps, and data center cooling applications.

Opteon 515B (R-515B), meanwhile, is a zero-ODP refrigerant blend consisting of approximately 91.1 percent R-1234ze(E) and 8.9 percent R-227ea. Chemours said is targeted at conventional chiller applications, offering a “balance of lower GWP, performance, and ease of adoption for customers transitioning from higher-GWP refrigerants.”

They are available now in “strategic countries,” with additional market availability expected to “follow aligned with market demand.”

Chemours Opteon line includes two-phase direct-to-chip and immersion cooling liquids.
