National Refrigerants, Limited (NRL) is an independent worldwide distributor
of refrigerants and all associated refrigerant management services.

COMPOSITION: A blend of HFC refrigerants R-125, R-143a, and R-134a (44/52/4 wt%)

APPLICATION: R-404A is intended for low and medium temperature refrigeration applications where R-502 was previously used. Most new equipment has been built for R-404A (and R-507 interchangeably). It is also possible to retrofit R-502 systems with R-404A.

PERFORMANCE: 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. Capacity and efficiency are very similar to R-502.

LUBRICANT: 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.
