Navin Fluorine to produce Chemours’ cooling fluid
10th May 2025
USA: Chemours has announced a strategic agreement with Indian fluorochemical company Navin Fluorine International to manufacture its HFO-based two-phase immersion cooling fluid.
According to Chemours, the partnership with Navin Fluorine marks an important step toward commercialisation of the fluid, providing critical capabilities and capacity – beginning in 2026 – to support the adoption of two-phase liquid cooling.
In March, Chemours announced a full-scale product trial of its new two-phase immersion cooling fluid Opteon 2P50 with Japanese IT company NTT Data and engineering firm, Hibiya Engineering.
The proprietary HFO-based 2P50 two-phase immersion cooling (2-PIC) fluid, was first announced by Chemours in 2023 for next-generation computing and electric vehicle technologies.
Chemours says that Opteon 2P50 has a GWP of 10 under AR6 and boils at 49°C. It is said to have a PUE approaching 1 and also claims superior performance capabilities compared to traditional or single-phase cooling technologies.
While Chemours has not revealed the HFO fluid behind Opteon 2P50, the company does hold patents on the application of the HFOs 153-10mczz and 153-10mzzy as immersion cooling fluids.
The fluid is part of Chemours’ newly expanded Liquid Cooling Venture, which will provide a portfolio of data centre cooling solutions, including direct-to-chip and immersion cooling technologies.
“The fact is, next generation chips alone can’t deliver the AI boom; the computing and resource demands created by this technology requires a new, integrated approach. Our deep expertise in cooling uniquely positions us to help bridge this gap,” explained Chemours president and CEO Denise Dignam. “Innovative liquid cooling solutions, like Opteon, can help significantly reduce data centre total cost of ownership through decreased energy, water, space, maintenance and capex demands, all while enabling next generation chip capability. Partnering with Navin Fluorine enables us to meet this critical market need.”
Two-phase immersion cooling involves a dielectric liquid boiling and turning into vapour when in direct contact with hot server parts. The vapour rises and condenses on a heat exchanger (condenser) above the surface, returning to a liquid state in a perpetual and passive cycle.
Liquid temperature remains constant. There is no need for pumps for the cooling process – only a small auxiliary pump is used to circulate the fluid through a filter.
Navin Fluorine International Ltd (NFIL) is one of the largest Indian manufacturers of specialty fluorochemicals. It belongs to the Padmanabh Mafatlal Group – one of India’s oldest industrial houses. Established in 1967, NFIL has manufacturing sites in Surat and Dahej in Western India and Dewas in Central India. NFIL’s R&D centre, Navin Research Innovation Center (NRIC), is located at Surat and Dewas, India and Manchester Organics, UK.
NFIL has experience with HFO production. In 2022 it opened a plant at its Dahej facility to produce the HFO 1233zd for Chemours’ competitor Honeywell.
