I am running a nitrogen assist passive cls. I have been told by several individuals that it is safe to vac down my solvent tank while my solvent tank is still in dry ice, after Ive “emptied” it into the run, and after I have purged off the nitro in the solvent tank.
I did it. I didn’t die. Should I dance with the devil again?
Look at a temp/vapor pressure chart…or whatever they are called. When the gas is cold cold, you can pull down on it pretty good in a safe manner. I think I don’t usually pull past -10 with my shitty gear. Operating your system under vacuum is a game changer.
