A blend of R-32, R-125, and R-134a that has very similar properties to R-22 in low and medium temperature refrigeration applications. R-407A has the closest property match to R-22 in a low temperature retrofit project compared to other blends on the market; however, there is a 10°F temperature glide. Most new supermarket and refrigeration equipment has been built for an HFC such as R-404A, R-507, or R-407A. New systems built with R-407A must have POE lubricants, and retrofitted R-22 systems would need the residual oil changed to POE.

Raki R134a
RAKI ® 134a ,This HFC refrigerant has been the standard OEM choice. R-134a is used in applications, including automotive air conditioning, chillers, medium temperature commercial refrigeration, household appliances,small self-contained refrigeration units and automotive air conditioning.

Raki R22
R-22 has been the dominant refrigerant in residential and commercial air conditioning and some very large centrifugal chillers for air conditioning and industrial process cooling. It has
Raki R410a
A blend of R-32 and R-125 that nearly forms an azeotrope, which means it has extremely low temperature glide and almost no fractionation potential. This blend has about 60% higher pressure than R-22 in air conditioning applications, and therefore should be used only in new equipment specifically designed to handle the pressure. Systems designed for

Raki R404a
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
Raki R407c
A blend of R-32, R-125, and R-134a that has very similar properties to R-22 in low and medium temperature refrigeration applications. R-407A has the closest property match to R-22 in a low temperature retrofit project compared to other blends on the market; however, there is a 10°F temperature glide. Most new supermarket and refrigeration equipment has been
Raki R507
An azeotropic blend of R-125 and R-143a intended for low and medium temperature refrigeration systems. Similar to R-404A in operation, most new equipment has been rated to use either blend. There will be
