R-404A has been the dominant refrigerant in residential and commercial air conditioning and large chillers for air conditioning and industrial process cooling and for medium and low-temperature commercial refrigeration applications.
R-404A has been the dominant refrigerant in residential and commercial air conditioning and large chillers for air conditioning and industrial process cooling and for medium and low-temperature commercial refrigeration applications. It can also be used as an aerosol propellant for pesticide and paint, or as a fire extinguishing agent. It is a primary feedstock for fluoropolymers.
R-404A has been subject to reduced production and restriction in new equipment since 2010, and production of the refrigerant is to end in 2020. The use of R-404A is allowed until the supply has been depleted. R-404A is non toxic and non flammable meeting the highest A1 Classification.
