I was helping my FIL clean out his parent's garage after they passed. We uncovered two of these. They appear to be air to liquid heat exchangers of some sort. I brought them home hoping to use them in my brewing process as a chiller. I got around to looking more into them today and can't seem to figure out a way to hook up liquid lines.
The red caps on the top (same on bottom), seem to be the logical places to hook up lines, so I removed them. They have threaded rods attached to both top and bottom caps, pulling the rods reveals a through passage of course, but the "spacers" between fins of the chiller are just small "bushings and each level can move and become out of sync. This makes me believe it is not a liquid cooler as the passages would not be liquid tight.
Labeled on one of the tops is "Air Flow --->"
