- Alternate refrigerant HFC-134a has been found to be substantially more reactive than CFC-12 in the US Navy submarine catalytic burner. The burner operates at 316°C and uses a manganese dioxide/copper monoxide catalyst, Hopcalite. The reaction of HFC-134a produced hazardous quantities of HF in the outlet air in excess of the established submarine exposure limits. No other hazardous products, such as carbonyl fluoride, were detected.
