I wanna see the OP's pics!
"gee, I'm not selling anything, and this thing is awesomenessly awesome, and ALL my friends have them, but I have only made THIS one single post,.........ever."
LOL... that's funny...
I have actually had mine for about one month and I paid full price for it. ($1300.00). I only know two other people on earth that have one, and I told them about it. After they saw mine, they bought one. LOL again... I have actually done about twenty extractions with mine and still have the same butane I started with... Still wondering if anyone has seen one besides me...

awesome post!Gee, funny how Joe posted virtually the same text on several websites but hasn't responded to many questions....
I'm fairly certain how this thing works, I built a system using the same concept but abandoned it as being too slow and went with a pumped system.
This thing has several major drawbacks, but I'll start with how It seems to function.
The tank at the top is the butane reservoir, the plant matter will go in the column like piece in the center and the oil is flushed into the bell shaped tank at the bottom.
The butane is recovered by removing the tank at the top after closing the valves and re-attaching it through a hose to the angled fitting on the bottom tank.
Recovery is achieved by Freezing the reservoir tank and heating the tank attached to the column. The butane will condense in the chilled tank.
Unless the chilled tank is cooled to at least -5 to -10 deg. Celcius there isn't going to be enough gas condensing in the chilled tank to make it worthwhile. It will take a considerable amount of time as well. I don't believe the 1 hour recovery time either.
The column/ recovery tank will need to be heated, either with hot water or a heating jacket. I saw electric heating jackets on the site a while ago.
If left at room temperature butane recovery would be minimal, it will need to be heated to push the vapor into the tank being chilled.
The other Major flaw is that the oil would have to be scraped out of the recovery tank unless you add alcohol to the tank before the recovery is started.
Notice how Joe mentioned adding alcohol like it was a bonus feature? It's necessary unless you want to scrape the oil out of the tank.
Then you have to boil off the alcohol. PITA.
You also would only be able to use N-butane since iso-butane condenses at a much lower temp. If you used lighter refills to charge this system you will have to chill it to around -20 to recover the butane.
Isobutane boils at -12, so you have to chill the recovery tank somewhat lower than that.
Without a pump in the system I can't see the recovery percentage being very good, maybe 75% or so and that would take some time.
The larger systems would take much longer to recover the butane, the website indicates overnight.
Without a valve to isolate the column with the plant matter in it and the recovery reservoir you are also essentially soaking the plant matter for the duration of the recovery process, there will be some unwanted compounds extracted due to this, not as bad as soaking the plant matter for an hour or more but certainly not desirable.
The column is joined to the lower recovery tank with a tapered flange connector, usually called a dairy flange or sanitary flange.
A split clamp joins the two, you can see the hinge at the front...
It will work, but again it's slow and you can only monitor pressure to judge when the recovery has completed. There's no indication how its progressing.
The quick connect couplers he's using are also prone to leakage, not good for flammable gas use.
