The loops are a continuous downward slope so the oil will pool right at the

and starving the compressors that I got scared.

Glenn, did you give any thought to circulating water through the keel,
and then using that to cool the condenser? That would allow you to
use a combination air and water cooled condensing unit, and if
anything went wrong with the keel loop (and I'm concerned that it
will), at least you have the air cooling as a backup.
