First time posting, I apreciate the help and patience in advance.
I Just purchased a closed loop system, currently plan to recover the butane passively.
I’ve open blasted in the past, but I am completely new to the recovery process, and have a few questions before I give this a go.
I have the following to work with
-CLS -Vaccum pump (standard pump not a recovery pump) -20lb tank of butane (not sure exact size, will have to check but looks like a BBQ tank) - two recovery tanks same size as the BBQ tank, red and blue valves
Heres where I am need of some help
I was told to pull a vacuum on my empty recovery tank prior to recovering.
Let’s say then I use all of the butane in this tank for delivering until it’s empty. I will once again be using it as a recovery tank.
Do I pull a vacuum once again, even though this tank has been exposed to butane? Just my guess but this seems unsafe.
My next question is,
if I have one recovery tank full of 20lb of butane, and another tank empty..
I do a run and say use 2.5 lb butane, and recover to the empty tank..
I now have 17.5 in one and roughly 2.5 in the other
On my next run, am I good to use the tank containing 2.5 lb to recover? Or do I need an empty tank that I can vac?
I apologize for that probably being hard to follow, but I guess I’m just confused on how to manage my butane between my tanks.
if you have any good resources you wouldn’t mind sharing my email is homiejohntrees@gmail.com
Thanks again!
