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.

Opteon™ XL blends

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 lower flammability (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. Opteon™ XL products are 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.

Nicht brennbare Lösungen für die stationäre und Transportkälte

Die Opteon™ XP Gemische haben sich seit ihrer Markteinführung auf der Chillventa 2014 erfolgreich in der Kälteindustrie etabliert. Gegenüber den herkömmlicherweise eingesetzten H-FKW besitzen sie signifikant verringerte GWP-Werte und sind als A1 (gering toxisch, nicht brennbar) eingestuft. So eignen sie sich ideal als Ersatz für die aktuell verwendeten Produkte mit hohem GWP in neuen sowie in bestehenden Systemen (Retrofit), um, wie in der F-Gase-Verordnung (EU) 517/2014 gefordert, zu einer Reduktion der CO₂-Äquivalente beizutragen.

• Opteon™ XP40 (R-449A): Dieses nicht brennbare (A1) Alternativkältemittel für R-404A ist das Flaggschiff von Chemours, ist von großen Komponentenherstellern freigegeben und wird weltweit verbreitet eingesetzt, vor allem in der EU, wo es sich als bevorzugter Ersatz für R-404A/R-507A etabliert hat. Im Vergleich zu R-404A besitzt XP40 einen um 67 % geringeren GWP-Wert, ermöglicht eine Verbesserung der Energieeffizienz um bis zu 12 % und bietet Supermärkten eine nachhaltige Option zur direkten Umrüstung ihrer Systeme.

• Opteon™ XP10 (R-513A): Besitzt einen im Vergleich zu R-134a um 56 % geringeren GWP-Wert. Zudem bietet XP10 eine vergleichbare Kälteleistung und Effizienz wie R-134a in zahlreichen Anwendungen, z. B. Kälte- und Klimaanlagen, Kaltwassersätze und Wärmepumpen. Zahlreiche OEM haben Opteon™ XP10 bereits freigegeben, darunter Trane, Smardt Chiller Group, Emerson, Bitzer und Johnson Controls.

• Opteon™ XP44 (R-452A): Ersatzkältemittel für R-404A/R-507A. Es besitzt nicht nur einen gegenüber R-404A um 45 % verringerten GWP-Wert, sondern ermöglicht darüber hinaus vergleichbare Druckgastemperaturen wie R-404A/R-507A. Somit eignet es sich für hermetisch geschlossene Systeme in TK-Anwendungen sowie für die Transportkälte. Tecumseh und Thermo King waren die ersten Unternehmen, die Opteon™ XP44 spezifiziert haben.

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.
