I've never run a Mk IV passively, but the Lil Terp took about 1 hour 45 minutes running 110F and a regular ice bath. Folks have cut it to 30 minutes, or so, using dry ice/alcohol for the recovery bath.

Hey GW,
I've just been reading through the Mk IVB instructions and noticed it's setup for running a one column lot. Would an extra port need to be added somewhere to properly vac down the column and pump foreline when changing out a column with partially recovered extract in the base?

Not sure I follow your question. The column is isolated from the pot by closing the vent and dump valves, before removal, so the rest of the system is still secure.
The high vacuum pump then evacuates the column through the discrete column recovery port.

Sorry, I likely have it mixed up somehow. I should have described what I'm thinking in a better way.
After I extract and recover a column I have the vent, dump, butane feed and column recovery valves closed.
At this point I can remove and replace the column with another from the same lot of material.
Then I would need to remove the recovery pump suction line from the discrete column recovery port to attach the vac pump and pump the column down.
When I go to replace the recovery pump suction line it would have atmosphere inside wouldn't it?

OK, I read you now. We have ours plumbed, so that we can just open and close valves. Once we change the column, we pull a high vacuum on it using the refrigerant pump, which we then valve off before injecting butane.
We open another valve in the same manifold later in the process, to use the recovery pump to recover the remaining column butane discretely.
Yup, so far all of WolfWurx turnkey systems were built around Haskels.
Good point, the Mk IVC is cart mounted and shares the center dip tube. Here is one currently being assembled for NV that demonstrates how they are set up. I'll post another picture when she is finished and ready to dance.
In this case, the Mk IVC is also using a 12" pot, and the same lid as a Mk VC. WolfWurx only imported (10) Mk IV 10" kits and only cart mounted one turnkey 10" system.
WolfWurx is actually in the business of engineering custom systems, vis a vis importing and retailing kits, so has since concentrated on strictly commercial systems, typically the Mk V and larger.
Might I suggest you build a Mk IVA lid and add the 10 degree angled view port shown on the Mk IVC lid?

Wow thats a mighty fine contraption
She sure is a beauty!
What 2" sight glass do you recommend for the view port? The angle is key for seeing the liquid level when filling close to the top?
Is that a protective cover material on the base of the cart that the tanks are on?
looking forward to seeing it all dolled up!

It was a treat to build something different. We have more orders for MKV's, but I would like to build more of these IV's.
Pangea,
We don't recommend any 2" view ports because we don't particularly care for any of the "view port" style site glasses.
We do however use the Illuminated 2" from Glacier Tank when its applicable. It does require a gasket change to Viton & careful attention to torque. They require a non standard battery, ect... Someone should build a good L veiwport!
Our new lids will have the veiw port angled 10 degrees toward the dump tube.

I don't know of any good welders in your area, but there is bound to be someone who can make sanitary welds.
Have you already bought the material? I can recommend someone up here for you. Do you have drawg's?
