**HP80 (R-402A), an HCFC-based refrigerant from DuPont, is the premier retrofit refrigerant choice for replacing R-502 in existing low - and medium temperature commercial refrigeration equipment such as reach-in and walk-in freezers as well as supermarket systems. HP80 (R-402A) offers the best combination of properties and is approved by more compressor manufacturers than any other R-502 replacement.
Alkylbenzene (AB) oil is recommended for optimum oil return. One compressor oil change to AB will typically remove 50% to 80% of the existing MO, which satisfies the recommendations and requirements of most compressor manufacturers.
