Counterfeiting in China is not restricted to Western brands. Zhejiang Juhua Co, an established Chinese producer of Giant brand refrigerants and a supplier of blend component R125 to Honeywell, is also under attack from fakers. And those counterfeiters are said to be passing off potentially fatal cocktails of refrigerants containing methyl chloride as R22.
In 2011, cocktails of R12 and methyl chloride (R40), sold as R134a, were thought to be responsible for a number of explosions and deaths in the refrigerated container industry. The methyl chloride reacts with aluminum, corroding the internal components in the system and creating trimethylaluminium, a volatile by-product that burns on contact with air.
