Germany’s Federal Motor Transport Authority have tested next generation air con gas HFO-1234yf reporting ‘no evidence’ of serious risk of explosion. The gas has a low ‘global warming potential’ and is being phased into production to meet new EU regulations.
The tests were commenced after the roll out of the new refrigerant gas, which will replace R134a, was delayed by challenges over safety. Engineers at Mercedes Benz had claimed a risk on flammability in the under bonnet environment if gas is released quickly following a collision.
Thierty Vanlancker, president, DuPont Chemicals & Fluoroproducts, said: “Testing produced no adequate evidence of a serious risk related to HFO-1234yf. In fact, the KBA testing indicated no safety concerns whatsoever for the product.
“The KBA report proves our earlier statements that it is only under extreme testing conditions that do not represent real-life crash scenarios that the refrigerant could be made to ignite. The results of the KBA testing confirm DuPont’s high level of confidence that the refrigerant can be used safely in automotive air conditioning.”
The KBS’s report follows the Society of Automotive Engineers (SAE) who also saw no safety risk in using HFO-1234yf.
