I have this desiccant dryer it’s worked well for me.

Every other heavy use I change out the cartridge and repack it with fresh beads. This is maybe a little excessive.
But since I’ve bought in mine Eastwood rebrands this same at a reduced cost.
You’re going to want to cool off the air as much as possible before it reaches the desiccant cell and have a drip tee before the desiccant cell as well.
I would have the desiccant cell is close to the plasma as you can mainly to give the air as much chance to cool as possible.
I would stay away from anything with a quarter inch fitting.
