Refrigerant R406a

R406a is an HCFC based refrigerant replacement for R12 and R500 in some commercial refrigeration system such as automobile air conditioner, walk-in coolers, ice machine, freezer and transport. It is used in some industrial refrigeration equipment as well.Replace R12 R500 Application Automobile air conditioner Medium- and low-temperature positive displacement equipment in supermarket systems and walk-in coolers Benefits Close match for R12. Has higher Energy Efficiency and capacity than R12. Works with existing mineral oil (MO) in many unitary and close-coupled systems. Alkylbenzene (AB) oil is recommended for optimum oil return.
