Does someone have experience with cooling units on solvent vapor degreasers?
I worked on such a machines around 1985-1990 and I didn't take any notices then.
Digital camera's didn't exist yet, so some experience is lost.
I now have a manufacturer who's asking to make such a unit for them.
These units are used to degrease items in the vapor of a degreasing solvent (trichlorothene was what I've seen mostly)
Strange phenomena happened in these degreasers, imagine a reservoir of +/- 6 feet x 3 feet x 6 feet high. Boiling solvent at +/- 80°C at the bottom and you don't smell almost anything.
You lower your hand slowly in this vapor and at a sudden, the solvent is streaming of your hands.
The cold coils on the upper part condense the vapor again so that it doesn't flow out of the reservoir.
