I'm not sure if this is the best section to post this but I figured i'd give it a shot.
I'm currently restoring two monitor top refrigerators, a 1933 and a 1934. Both are methyl formate and work great.
I'm looking for anyone experienced with these as I am trying to learn as much as I can in regards to their operation and history.
Now the reason I picked this section. 1927-1932 MT's used SO2 as refrigerant. Then 1933-1934 used methyl formate. And then they went back to SO2.
I'm curious if anyone knows why GE only used methyl formate for 2 years and then went back to SO2?
I'm also curious if anyone has considered using methyl formate in modern units. Reason being it seems superior to R290 as it operates below atmospheric pressure ergo will not leak into a room rapidly if the system develops a leak. Obviously methyl formate is highly flammable, but then again so is R290.
Please, go easy on me. Trying to learn ;)
