I have a medium/large size chest freezer that is in great working condition. I use it as a cold conditioner for beer kegs, for home brewing.
I have it set up with a Johnson analog controller and a manifold to keep 9 kegs under constant co2 pressure. If you are interested in it as a home brew setup let me know, I also used it for fermenting beer and it will hold four 6.5 gallon carboys with some additional space. It has been on a controller sense it was new, so it has very little running time. It has never been used to deep freeze.
The outside has some scratches and dent consistent with its age and use. It is a very good unit.
