@Cosmicmonkeybear What blend of solvent do you run? And do you ever clean out your tank? I use 70/30 butane propane
I found this thread Extraction & van der Waals Force
I noticed my psi in my tank at room temperature was almost 100 at room temp and only got down about 50psi at -30. I emptied my tank there as a decent amount but if ice in there as well and when I replaced it. So I’m thinking I must’ve been told running with a really high% of propane as well as having a decent amount of moisture in there.
