The United States Environmental Protection Agency (EPA) has released proposed Significant New Alternatives Policy (SNAP) Rule 27, expanding the list of acceptable refrigerants for motor vehicle air-conditioning (MVAC) systems, including R1234yf for buses and heavy-duty vehicles, plus the addition of R444A, R456A, R452A, R480A and R1234yf as acceptable retrofits in certain applications. Mobile Air Climate … Continue reading US EPA proposes YF for buses and heavy vehicles, lists potential retrofits

Honeywell’s proposed R134a to R1234yf retrofit

By Refrigerants Australia executive director Dr Greg Picker With the start of the transition to R1234yf in significant numbers in new vehicles and the HFC quota likely to impact refrigerant supply and price, the mobile air-conditioning industry is trying to assess what refrigerants they can use in a retrofit situation.  The situation seems complicated and … Continue reading Retrofitting refrigerant in automotive applications: What are the current rules?

Koura has launched Klea Edge 444A across the UK and Europe and positioned it as a direct aftermarket replacement for R-1234yf in automotive air-conditioning systems. The new refrigerant is claimed to offer enhanced vehicle performance and reduced environmental impact at a lower cost than current alternatives but has a higher global warming potential than the … Continue reading Just because you can… Koura publishes retrofit guides

Chemours and Honeywell have announced the development of a “retrofit approach for vehicles using the legacy R134a mobile air-conditioning refrigerant” that enables these systems to run R1234yf. As Honeywell rightly points out, there are hundreds of millions of cars on the roads “potentially leaking R134a every day.”   Replacing all that refrigerant, with its global … Continue reading Retrofits to return: Why it won’t be simple

R1234yf-gauges

Refrigerant manufacturer Honeywell, which co-developed R1234yf with Chemours, has filed an application with the United States Environmental Protection Agency (EPA) seeking approval for the use of YF as a retrofit refrigerant in R134a systems. This step, previously considered unlikely due to YF’s A2L mild flammability rating, was motivated by growing concern about the availability and … Continue reading R1234yf retrofits coming after all?
