LANSDALE, Pa. (Jan. 5, 2012) — The Mobile Air Conditioning Society (MACS) is advising all industries using refrigerant R-134a to be on the lookout for possible contamination, and it has posted information on the issue from the Society of Automotive Engineers' (SAE) Interior Climate Control Standards Committee.
MACS has been following recent reports of R134a contamination, including from Neutronics Inc., a global supplier of gas analysis and handling technologies. In a Dec. 21 press release, Neutronics said all industries should test all cylinders thought to be virgin R-134a, including new 30-pound cylinders.
MACS has posted on its website information from SAE ICCSC to give more context on the issue. It also noted that the refrigerant R-40—which is not acceptable as a substitute for R-134a—will be discussed during its upcoming convention, Jan. 17 in Las Vegas.
Neutronics said in the release that several months ago its Refrigerant Analysis Division was engaged by the ocean going shipping industry “to assist with a R-134a refrigerant contamination problem that reportedly resulted in several deaths and a significant interruption to ocean going transport.”
Much of the possible contaminated refrigerant, Neutronics said, contained significant quantities of R-40, a toxic and flammable material not suited for R-134a refrigeration air conditioning systems.
Founded in 1981, MACS is the leading non-profit trade association for the mobile air conditioning, heating and engine cooling system segment of the automotive aftermarket.
