The propane regulator is something my pops put on the tank.. I just unscrewed it.. it's like a little round disc ..

Anyway the reason why I didn't take it off before is because I was having trouble finding fittings to go on the piece that the regulator screwed into.. well I got a reducer that fit.. and now things are good.. I am blasting propane out at super high PSI's

I vac'd my system.. filled it with straight propane.. HOT DAMN! THIS SHIT WORKS!!

So far I've seen -13F.. that didn't last long though.. temp rose.. I ain't getting that crap like before.. where the temp would drop.. then rise.. then drop.. it's staying well below 20F this time.. It seems that the propane likes a high highside pressure.. of around 200 to 210PSI.. and the low side around 5PSI to 10PSI.. although if your compressor was strong enough to put the system in a vacuum with that high of a highside.. then the propane would work even better.. cuz vacuum is good

I filled that sucker up good.. letting it sit now for like 10 minutes.. so the temps will even out and what not... Then I will add more or release some.. whatever needs to be done.. this is a 25gallon tank I am using.. I think.. costs 10 dollars to fill it up.. I used 3 cans of 134a last night.. each can is 12oz.. cost me 3.50 a can! WHAT A WASTE! PROPANE OWNZ J00!

I was really afraid at first.. to screw around with propane.. hot temps.. etc.. but I got over it.. and did it..

My whole condensor is hot now.. even the very last pipes are warm.. The dryer is around 90-100F.. I believe that the dryer should be cool.. but.. the system seems to be working fine even though..

Time to roll

Oh, the only down-fall to using propane is there is a chance of having a small amount of air in the tank.. As far as I know they don't vacuum your regular residential tanks before filling them.. but oh well.. still works fine.. as long as you don't have moisture in your system it's all good.. plus.. the propane smells like ASS..
