Those are all awesome points! I considered getting a dew point monitor just so I can actually see what I’m getting at the tool point. I’m just doing this as a hobby… my shop in Wisconsin is air conditioned so I’m not to concerned of high ambient temps in the summer. If anything I’m more concerned about it AT TIMES over the winter because I’m bring my trailer in and snow melts off and the water on the floor just has to evaporate… so it has definitely been stuffy in there at times over the winter.
Putting space behind that copper tubing and the wall is a great point and very cool to see the success people have had improvising something to get the bulk of moisture condensed out! It clearly works from all the videos I’ve seen.
You touched too on lowering the air temp going into the plasma cutter… that there is a max temp. This further had me thinking that maybe I would add some kind of transmission type cooler to the side of my compressor as well. Seems simple enough and very effective. Would only help lower the air temp even more before in my case going through the pressure drop in the dryer I ordered.
Only thing I had to consider was if I could set the operating pressure of my compressor to turn on around 150 psi and off at 175. Fortunately I was able to dial it up from the 150 it was at from the factory. The pressure will enter the dryer where it will drop dramatically to about 90-100 psi if I recalled. That reduction in pressure allows any moisture down to about 50 deg F dew point to boil off. So doing what a whole wall of tubing would do in just a few feet of space.
But yes this is a pretty interesting topic. And one I just wasn’t seeing any specifics on. So hope others can find this useful as well!
