As the working pressures of RS-45 (R434A) are lower than 24 bar, there was no need to change the safety valves and other parts rated to 24 bar (348 psi) which would have been necessary with a conversion to R404A, R507, R422A or R428A

Since RS-45 (R434A) is compatible with all refrigerant oils, including mineral oils, installations using this lubricant do not need to move to a POE, which would have been necessary with R404A, R507, R407C or R427A, thereby reducing the conversion time, cost of oil, emergence of new leaks and the constraints imposed by the use of very hygroscopic lubricants.

RS-45 (R434A) low temperature glide of 3°F enables the system to be directly charged with RS-45.  From a technical standpoint, there is no need to remove the remaining refrigerant because no fractionation of the mixture would occur as would happen with R404A or R507.  However, good practice protocol and EPA guidelines call for refrigerants not to be mixed.

RS-45 (R434A) achieves good condensation and it is therefore unnecessary to charge the condensers or make any changes in this regard as would be the case with R404A and R507.

Owners can continue to use an A1 safety classification product, thus avoiding toxic or flammable chemicals like ammonia and hydrocarbons, respectively, which, amongst other things, also requires a major overhaul of facilities.

RS-45 (R434A) does not involve any significant loss of cooling power compared to R22 in contrast to what would happen with R422D, R417A, R407C and R427A
