I have a few of the early 1900 Delco Light plants and happened to see this refrigerator ad. The light plants were 110 volt or 32 volt DC. Ad doesn't say which voltage and I assume you could get it either way. I wonder how many btu it was rated for. Ad says it was designed for a 20 degree evap just like the GE specs. Anyone want to guess how many pounds of SO2 this thing would take? And look at the size of the compressor pulley, must be 12-14 inches in diameter? Looks like hi torque capacity and low rpm!

Some of the deep-woods rural areas here were very late to get REA electricity. I saw one of these still in use 50 years ago.
There was a (what I took at the time to be 24 volt DC judging from the batteries) "Delco plant" on a cement slab in a shed, and a DC refrigerator in the house, with the condensing unit remotely located in the utility room, it had a metal mesh cover over it instead of being open like the photo. It made a sort of "wump, wump, wump, wump" noise when it ran. The Delco plant was particularly clever in that it didn't run all the time, only when it sensed an electrical load.
