HFC - R407C A blend of R-32, R-125, and R-134a which has very similar properties to R-22 in air conditioning equipment. There is a slight decrease in capacity and efficiency, however R-407C can be used in essentially the same equipment to perform the same job with only minor engineering modifications. It can also be used in medium temp R-22 refrigeration systems. R-407C has a 10F temperature glide. New systems built with R-407C must have POE lubricants, and retrofitted R-22 systems would need the residual oil flushed with POE. |
