Genetron® 32 (R-32)

Genetron® 32 (R-32) can replace R-410A in new air conditioning and chiller equipment. R-32 has GWP of 675, which is 68% lower than R-410A. It is mildly flammable, which means you must observe applicable regulations and standards for handling A2L refrigerants. As a straight R-410A system replacement, R-32 has around 10% more capacity. As a result, a new system built for R-32 will deliver higher cooling capacity, or require smaller displacement compressors to achieve the same capacity. Efficiency gains over R-410A are expected, provided the system and component designs have been optimized for R-32.
