Chemours

The brand you trust with 85 years of experience

With more than 85 years of experiences in the world of refrigeration, Chemours offers the right solutions for their customers in non-regulated markets. Freon™ remains a trusted brand for our HFC products, even as the industry moves towards low GWP solutions like the Opteon™ portfolio.

A new molecule for high-temperature applications 

The brand-new molecule, HFO-1336mzz(Z), forms the basis for the working fluid Opteon™ MZ, which allows end-users to expand their heat-pump and ORC application envelope significantly. It can deliver temperatures above 160 °C and is stable to more than 200 °C for organic Rankine cycle (ORC) and waste heat recovery (WHR) applications. In addition, it has excellent environmental properties with a GWP below 10.

The latest innovations in the Opteon™ portfolio for stationary applications – Opteon™ XL blends are mildly flammable refrigerants with very low GWP for new equipment designs. 

Opteon™ XL blends will enable the market to further decrease the CO₂-equivalents to lowest levels. They offer similar performance compared to the current HFC technologies they are designed to replace, which makes them easier and cost-effective to apply in new equipment without major modifications. Classified as mildly flammable (A2L), these products allow much higher charge sizes than other flammable refrigerants, especially hydrocarbons, and can be safely used by following the applicable codes and standards. Hence, the Opteon™ XL blends offer the optimal balance in terms of performance and properties. 

• Opteon™ XL20 (R-454C) and XL40 (R-454A):  These low-GWP replacements can be used as substitutes for R-404A and R-22 (R-407C) technology.  Opteon™ XL40 offers a GWP of 238 as well as superior performance with respect to cooling capacity and efficiency.  This enables a reduction in CO₂-equiavalents of 94% compared to R-404A. Opteon™ XL20 is a closer match to R-22 (R-407C) based technology, but it is also a valid solution for R-404A equipment. With a GWP 148, it falls under the important maximum value of 150 in the F-Gas regulation and Ecodesign. 
   
• Opteon™ XL41 (R-454B) and XL55 (R-452B): Both Opteon™ XL41 and XL55 are excellent replacements for R-410A in new and existing equipment. XL41 provides the lowest GWP available (466) of all near-drop-in solutions with a reduction of 78% compared to

R-410A. In addition, it is a very close match to R-410A and in some cases even provides superior performance with respect to capacity and efficiency. XL55 offers improved performance compared to R-410A while maintaining design compatibility. It also has the lowest flammability compared to other industry-tested R-410A alternatives. It is gaining significant interest from OEMs like Trane which has already exhibited the first air-cooled demonstration chiller, AquaTrine™, designed for use with Opteon™ XL55, and Bitzer which has XL41 and XL55 compatible equipment commercially available

Non-flammable solutions for stationary and transport refrigeration.

Opteon™ XP blends have been successfully adopted in the refrigeration industry after their introduction at Chillventa 2014. They offer significantly lower GWPs than the legacy HFCs and are classified as A1 (low toxicity, non-flammable). Thus, they are ideally suited to replace the current high-GWP products not only in new, but also in existing equipment (retrofit) to reduce the CO₂-equivalents demand under F-Gas regulation (EU) 517/2014.

• Opteon™ XP40 (R-449A): the Chemours flagship non-flammable (A1) replacement for

R-404A refrigerant, is approved by major equipment manufacturers and has already seen widespread global adoption, particularly in the EU as the R-404A/R-507 replacement of choice.. XP40 provides a 67% reduction in GWP over R-404A, while improving system energy efficiency up to 12% and offers an excellent direct replacement option for supermarkets that are looking for a more sustainable retrofit solution.

• Opteon™ XP10 (R-513A): Provides a GWP reduction of 56% compared to R-134a. XP10 offers an excellent capacity and efficiency match to R-134a across a range of applications, including refrigeration, air conditioning, chillers and heat pumps. A growing list of OEMs have specified Opteon™ XP10, including Trane, Smardt Chiller Group, Emerson, Bitzer and Johnson Controls.
   
• Opteon™ XP44 (R-452A): A refrigerant replacement for R-404A/R-507A. With a GWP reduction of 45% compared to R-404A, XP44 also matches the discharge temperature of R-404A/R-507A, which is very critical for low temperature hermetic systems and transport applications. Tecumseh and ThermoKing have led the way in specifying Opteon™ XP44.

R-134a replacement for automotive & stationary applications

Opteon™ YF is a non-ozone depleting, low global warming potential (GWP) refrigerant. It was developed to meet the EU Mobile Air Conditioning (MAC) Directive for phase-out of high GWP refrigerants for automotive air conditioning. With a GWP of <1, Opteon™ YF easily meets the EU MAC Directive.  The use of HFO-1234yf has grown exponentially and by the end of 2017, an estimated 40 million vehicles were utilizing HFO-1234yf in their air conditioning systems. Opteon™ YF is also a very good solution for stationary equipment running on R-134a, as shown by pilot projects and field trials.
