more than likely gonna need a bigger consumables budget tooâŚat that rate youâre paying roughly $300,000 a year on dry ice alone (if you operate 300/365 days a year )

I pay $3/lbs

At $3/lb itâd be $900,000 
Edit: I just wanna say, Iâm a proponent of getting the job done by whatever means necessaryâbut this is why I always start with specifying chillers for clients.
If you want to do it with speed, you either eat into your margins with dry ice or you make the upfront capital investment.

My friend runs 10 6Ă48 columns a day he goes through roughly a 500lb bin a day in a 10 column day at max 600lbs a day . His cost of ice is 75 cents a pound although expensive at that level of production 1 column is paying for ice for the whole week. I get my ice at .55 cents a pound so it can be even cheaper depends on location. At that scale of a system a chiller would be 30-60k so some people would just rather factor in the cost of dry ice especially if it is cheap . 1$ a pound is pretty expensive for bulk dry ice. Also if the system was ran for 300 days it would generate 6 million$ selling good extracts at 4-5$ per gram so 300k for dry ice at the end of the year isnt . Especially when it might only be 150-200k.

Speaking of coils, I saw some killer shit the other day in one of Subzeroâs solvent tanks, and they called it a âCold Fingerâ. Apparently, itâs like a small pot that extends into the solvent tank that holds your slurry down into the tank. Maybe this is a common thing, but it was the first time that had every seen some shit like thatâŚ

Dry ice not so cheap in Canada eh? You should have a discussion about it in the Canada thread. Someoneâs gotta have a cheaper source than that.

you cant figure it out and you were giving me a hard time?
im learning slowly tht you guys are all about recovery volume. Cant regular ice take place of alot of the dry ice by running through ice/salt slurry prior to condensing?

Hi! so no nitro push needed? Would be one TRS21 enough for 2.5lbs system with 25lbs of solvent? thanks!
Yes, no nitrogen needed, the pump is used to create the pressure differentials where you need them.
Iâm not sure on the trs21, it might be a little undersized. Worst you can do is try and see if it works or not.
