An automotive coolant Daimler claims is too dangerous to use in their vehicles, despite the warnings from the European Union to cease usage of an older coolant considered harmful to the environment, was found to be safe according to a report made by EU scientists.
Reuters reports the coolant in question, the Honeywell and DuPont co-developed R1234yf, posed “no evidence of a serious risk in the use of [the] refrigerant in mobile air-conditioning systems under normal and foreseeable conditions of use” as reported by the Joint Research Council in their findings last week.
Daimler, who claimed the coolant emits a toxic gas when burned, defended their position against using R1234yf, claiming the research “too restrictive,” preferring an option to develop a system using carbon dioxide as the cooling method, though said system is years in the making.
Meanwhile, the automaker uses R134a, an older coolant that the European Commission has found to have a global warming potential 1,000 times that of carbon dioxide while developing an air-conditioning system; EU rules state new coolants must have no more than 150 times said potential. As a result, the Commission has begun legal proceedings against Germany over Daimler’s current action on the matter.
R1234yf is currently 500,000 cars according to Honeywell, who expects the coolant will be in more than 2 million units by the end of 2014.
