Easy to use, Low GWP Refrigerant to Directly Replace R-22 and R502 (ASHRAE R428A) in a Wide Range of Conditioning and Refrigeration Applications.
RS-52 is a non-ozone depleting, near azeotropic performance refrigerant blend for direct replacement of R22, R502 and interim ozone depleting blends like R402A, R403B, R408A and other HFC solutions. RS-52 can be implemented without having to change existing lubricants, components, or equipment (except the case of small adjustment to the expansion device).
RS-52 is compatible with all traditional mineral oil/alkyl benzene lubricants and synthetic esters (POE). RS-52 is a capacity match for R502 and exhibits a temperature glide of less than 1°C.
RS-52 (ASHRAE R428A) is a low global warming potential (GWP) and zero ozone depleting potential (ODP) performance refrigerant to replace harmful and outdated HCFC and HFC chemistries.
