Hey, May I know what is the low temp in your tank do you need? Does it have a insulation cover?

Hi Dear,

Some need -40℃， some need -60℃， some need -80℃， what cooling temperature do you need?

15

I never paid much attention to temps on my butane tank when I extracted. I would basically submerge my butane in dry ice for a good half hour or so before my flood… I would prob like it to be -60- -80. From what I have read dry ice is north of -100

16

-60 to -80 somewhere in that region

17

I thought you weren’t got at selling services. You’re great at it!

if you’re gonna play with chiller math, you need to settle on a scale. I suggest C rather than F.

dry ice sublimes at -78C

dry ice acetone hits that temp, dry ice + ethanol might be a couple or 4 degrees warmer at -74C

Thanks man, yeah after doing some digging on here I think I’m gonna try some experimenting with dry ice and a magnetic pump to circulate a subzero friendly liquid through the jacket. I think it might have been you that was talking about it in a post I came across last night :+1: After looking at some of the diffrent chillers im not certain now that will be a good option. Most of the bigger ones I came across seem to need 3 phase and are mind boggling expensive. I should have bought this stuff when I was actually making a decent income within this market years ago​:rofl:

Make sure of two things (at a minimum): don’t get dry ice in your pump and make sure your pump is rated for flammable liquids and the temperature you’re going to be running at.

So not a pond pump?

:+1: I’m going thru the threads now. Yes I agree with your advice with the minimum 2 things for sure. I came across a good discussion on them last night and now I cant find it. Someone was experimenting with different ethanol pumps i think it was @cyclopath. It seems there is not many options for pumps that meet those requirements.

23

Oh man, I read a few discussions with people using them. I cant see that working out well imo.

24

I’ve only tried a couple or six Cold ethanol pumps

the hive however has done a great job of exploring that particular problem.

(don’t neglect to explore the links underneath the first post…)
