For using in a 1/4 R12 compressor. I want the loest temp possible for heat load around 140w.

409 or 401B would be the coldest for the longest time.
R502 might get it cold, but compressor will not last very long.

Im using R409a, but got about -28c w 140w load
I want -38c :D
I think r22 would give me that :)
