how long is it taking for you to do a run? what size column are you using? At those temps i feel like my system would crawl. Im using a 12" base with a 4x24 column and i keep my water sitting around 75-90 depending on how much and how long im running. I can do 2 passes and one soak on a full column and pour out my product in about 2 hours or so

I feel there's a huge reason to introduce heat. It speeds up recovery time immensely. With out heat run times slow to a crawl. We've found that the product isn't jeopardized by introducing heat under a hundy to speed recovery times
Trying out a Terrp sleeved 900 gram tube today...
Doing some experiments, first time with a dry ice sleeve and its a fucking bitch to work with...
I want to run compressed CO2 for the sleeve, instead of dry ice...
If everything works out, thinking DUAL Terrp 900 gram tubes per run...

That system is becoming quite impressive krunch! I have been tossing around the idea of adding a valve at the column base for awhile now on my bhogartesque system to allow a flood -> shower approach. My question is: how does this alter your operating procedure? I was having trouble following the plumbing in your recent picture. It appears one column is directly from the recovery tank, while the second runs through the manifold. I was theorizing the flood being accomplished by tank pressure alone, open the column valve, and dump the column while throttling the manifold to push the rest of the solvent out ala a standard "shower" run. Any thoughts are welcome.

Are you still using the manifold? I've been using a BHOgart for about a year now but am building my first system from scratch. I'm thinking about going with a similar design as yours and continuing to use the test charge manifold. I haven't locked down a design yet so any input on using the manifold at cryo temps would be nice. Thanks!
Just took the manifold out of the equation, no need for it if you have a gauge on top of the tube...

So you got your blue low side gauge on the top of the tube and the red high side gauge on the collection pot. I was thinking about adding the high side gauge onto a tee fitting in-between the recovery pump and the recovery tank. I guess I became too reliant on the simplicity of the manifold. Thanks again for all the help.
Picked up 15 3" high pressure clamps for $100!!!!

Where? Locally? I'm in the bay also.
It was a Ebay "Buy Now" deal....
6 columns at a time?
Or you could make a four banger by setting one set of columns on top of and at 90 degrees to the other on the central pipe, and use the other two ports as light and vision/camera ports.
We had one set up with four columns for storage, and it looked a lot like a cross between a space probe and a steam calliope!
Could be used for a thermocouple port to keep track of the puddle temperature, and as a loading port for distilling butane.
Makes a killer conversation piece with pretty women!
I thought about adding a Y and another ball valve so i could do multiple tubes back to back a little faster but i dont know how much faster it'd be, probably not much. For feeding 2 columns at once would i need like 50PSI coming in to get an even complete soak of both columns? Going to be building another machine here soon

A "Y" with 2 2" X 36" columns work great. But I hate unpacking them and having to heat them up...
I like running a Terrp 3" sleeved column. Easy to pack and unpack and you can use the sleeve for warm water to liquify the butane vapor in the column...
This lid is for a second system, hate just standing there waiting for the butane to recover. Might as well run another system while waiting!
