Honeywell hits back over ‘poisonous’ 1234yf claims

Honeywell, one of the manufacturers of HFO-1234yf, calls refrigerant report ‘misleading and biased’.

Following the release of the report by German university Ludwig-Maximilians-Universität München (LMU Munich), which questioned the safety of the refrigerant 1234yf, Honeywell has issued a statement slamming the research reults.

It said: “Contrary to the misleading and clearly biased assertions of the report’s authors, carbonyl fluoride (COF2) is in fact a well-known breakdown product of HFO-1234yf that has been publicly studied by leading experts in the automotive industry.

It was studied in the 2007-2009 Cooperative Research Program (CRP) conducted by SAE International, the world’s leading automotive engineering organization.

The SAE CRP reviewed the COF2 data, included it in its risk assessment, and concluded that HFO-1234yf is safe for use in automotive air conditioning.

In March, the EU’s Joint Research Centre also reviewed this data and again concluded that HFO-1234yf is safe for use in automobile air conditioning. 

COF2 is also formed during the burning of the current automotive refrigerant HFC-134a, used in hundreds of millions of vehicles worldwide today.

When COF2 does form in such conditions, it only lasts for a fraction of a second, which is not long enough to put bystanders, passengers, or first responders in any danger.”
