Refrigerant Gas (Freon)

Sun-air® R-22

R-22 is an HCFC refrigerant used for residential and commercial air conditioning and for medium- and low-temperature commercial refrigeration applications, including: food service, supermarket display cases, food storage and processing, and transport refrigeration systems.

Sun-air® R-134a

R-134a is an HFC retrofit refrigerant for R-12.  It is used in new medium- and high-temperature stationary commercial refrigeration, as well as chiller systems and home appliances. In addition, it can be used to retrofit existing R-12 refrigeration and air conditioning systems. It is also the global standard for new mobile air conditioning and can be used to retrofit existing R-12 mobile air conditioning systems.

Sun-air® R-407C

R-407C is an HFC refrigerant replacement for R-22 in positive displacement systems such as new or existing residential and commercial air-conditioners and heat pumps. R-407C offers similar performance to R-22 and can be used to retrofit existing R-22 air-conditioning systems. R-407C can also be used to replace R-502 for some existing medium-temperature applications with evaporator temperatures above +20°F (-7°C).

Sun-air® R-507

R-507 is an HFC replacement option for R-22 and R-502 in commercial refrigeration systems. It can be used in new and existing systems, and provides very similar performance to R-502 over the entire operating range.
