The Red Beards and I think all of the Terpenator units columns can be detached and packed and frozen before running.
They also use dry ice or a alcohol/salt bath to chill the butane tank way way down to -70, maybe all the way down to -100° F
From the recent reading I've been doing, chilling to these temps using a CLS, have been working to extract and in-line de-wax simultaneously.
RB suggested to use descending micron sized meshes stacked at the normal exit end. This would increase the speed of the in-line dewaxing process.
If I were currently looking for a CLS, I'd highly recommend first the MkIIIa
You'll end up spending just over 2 grand with ALL the necessary equipment, plus all the bells and whistles.
*The most advantageous aspect of buying the MKIII...

I am not aware of any of these CLS vendors that include all the other necessaries on order for these units to actually operate..
Like the Butane tank, Recovery pump, you want SS braided hoses, other miscellaneous items...
So even that Best Value CLS, that only holds 60 grams will still cost.about 16,17 hundred dollars.
The Red Beard units are looking VERY good, and I hear that; although this is a very small business right now...their customer service is fantastic.
Their 150 gram unit is 1250$.. That is 150$ more than the Best Value unit, for almost triple the capacity.
Here is a link to a thread...good read...
Except for the bickering..lol
Seems RB is good people to me
