CHEMOURS (DUPONT) FREON 404A X 9.5KGS HFC REFRIGERANT GAS (CHINA)

Freon™ 404A (HP62) has been the long-standing HFC replacement for R-502 and R-22 in refrigeration applications. HFC-404A is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in certain end use applications in the U.S. market. There are no U.S. regulations currently impacting the HFC service market. Refer to the Summary of U.S. EPA SNAP Regulations Pertaining to Refrigerants.

Learn about Opteon™ XP40 (R-449A) and Opteon™ XP44 (R-452A), low global warming potential (GWP) hydrofluoroolefin (HFO) based refrigerant replacements for R-404A in new equipment and for retrofit of existing equipment.

Lubricant Recommendation
POE

A blend of R-125, R-143a, and R-134a intended for low and medium temperature refrigeration applications where R-502 was previously used. Most new supermarket and refrigeration equipment has been built for an HFC such as R-404A, R-507, or R-407A. It is also possible to retrofit charge R-507 systems with R-404A. R-404A has slightly lower pressures than R-507 (from the small amount of R-134a added), and generally both blends have slightly higher pressures than R-502. R-404A requires polyolester (POE) lubricant, which is usually charged into new equipment. If retrofitting existing equipment, the original oil must be replaced with POE.
