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 for an HFC such as R-404A, R-507, or R-407a. It is also possible to retrofit charge R-507 sysytems R404a. R404A has slightly lower pressure 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.
