I saw this at a surplus auction:

Its a 2 stage freezer, 1st stage is R134a/R404 and second is R290/R14 (I think, it was some double digit R I've never seen before mixed with propane). Total charge was on the order of 20 oz, but I forget the breakdown. They only wanted 5 bucks for it, but it had to weigh at least 200 pounds and ran off 220v, so I was fairly skeptical I'd be able to get it off my truck and if I did be able to run it at all. Assuming I can get a hold of it, would it be worth trying to make a chiller out of it? What kind of load do you think something like this could hold?
We've got a few of these around where I work and they hold -90C pretty well, but I'm not sure what the capacity would be like. I'm thinking maybe its not worth the massive trouble to convert one. Thoughts?
