DuPont Fluorochemicals has introduced three refrigerants in its more sustainable DuPont Opteon family of products.
These refrigerants far lower global warming potential (GWP) than the products they are designed to replace and will enable compliance with a growing number of regulations that limit the use of high-GWP refrigerants.
The company expects its new family of products will reduce greenhouse gas content of refrigerants by about 245 million tons CO2 equivalent worldwide by 2025.
To enable regulatory compliance, DuPont has developed a full portfolio of low-GWP, high-performance refrigerants for a wide variety of applications. The new Opteon family is based on hydrofluoroolefin (HFO) technology and includes more than a dozen products that are in development or already commercialized.
DuPont is introducing three new low GWP products for commercial refrigeration under the names Opteon XP40, Opteon XP44 and Opteon XP10. Opteon XP40 is a flagship refrigerant that can effectively replace the refrigerant R-404A, which has one of the highest GWPs of the common HFCs and is extensively used in commercial refrigeration. In addition to providing more than 60 percent reduction in GWP, extensive testing has shown that Opteon XP40 delivers energy efficiency compared with R-404A, DuPont says.
Opteon XP44 is a lower GWP replacement for the refrigerant R-404A and has been designed specifically to meet the demanding operating conditions of transport refrigeration. Opteon XP10 is a lower GWP replacement for R-134a for refrigeration and other applications.
DuPont says it has additional Opteon products in its pipeline, including high-performance fluids for targeted applications such as chillers, high-temperature heat pumps and organic rankine cycles. The entire Opteon family offers properties and performance that are close to the incumbent HFCs to allow a smooth and efficient transition to more sustainable products.
