we have played around with diesel storage and condensation is the problem in SC. Additives help
When you use plasma cutting the air has to be nearly pure dry or you can't get the plasma arc to manifest.
The two critical things and maybe it is 3
1- free tank of containment and fill 105%. Leave no room for air.(which holds the h2o)(some consider that 2 things. I see it as everything inside the tank)
2- use compressed air thru a purity filter and only send that to the tank.
I'll say the filters last 10hrs in SC when it's humid af. But take them in a climate controlled space for a week they dry out. We have 5 in service/5 drying each week. And we are cheap. If we were a big place we'd just spend 25 00 a day on filters. I save toilet paper by only shitting at fancy hotels all dirty af too. Lol
It can be done but you're on spot. I've basically giving my idea to protect only me away. Cool
