How about those situations where the automated Mk II just isn't big enough, even running a 3" X 36" column, holding approximately 2 pounds of material?
I designed, but have yet to complete building a Mk IV Terpenator, because it was an attempt to gain more surface area than was available in a 6" diameter spool, by laying it on it's side, and Glacier Tank has since been able to arrange for 8", 10", and 12" X 12" sanitary spools.
Hee, hee, hee, go big or go home! We are building two Mk V's based on the 12" X 12" sanitary spool, with 4" X 48" columns, holding approximately 5 pounds per run.
The Glacier Tank parts and prices are listed, and the Paramount Supply parts list will follow as soon as the bids are received.
Pacific Semiconductor, Inc (PSI) has agreed to build us another control system, and has designed one half the size of the original and estimated to cost about $840.
A Hoffman electrical enclosure will still be required, as will be the three pressure switches which control the process through the Panasonic programmable process controller.
As before, the valves will all be pneumatic, so that the enclosure containing the Mk V can be kept spark free.
It is our intent to run it with dual CPS TR-21 recovery pumps with after coolers, to keep speed up, and a CPS VP6S 6.2 cfm single stage vacuum pump for initial and final evacuation.
The following list shows two lower spools and an extra set of columns, though only one is required. They are included as extras to speed up operation and to keep the machine operating.

An option to the Appion G-5 or the CPS-T-21, is the Caresaver Universal refrigerant recovery machine, which can be viewed at http://www.rda-eng.com/caresaver.html
They are designed to pump R-600 and R-600A refrigerants, which should gladden the hearts of the fire marshalls.
More information can be had from Mathew Ellis at firstname.lastname@example.org, or at 720.412.5194, and they sell for $2380 ea, plus applicable taxes and shipping, in units of one and $2240 for five or more.
I got the machining and welding done, and assembled the Mk V tank for a pressure test using the new high pressure clamps. At 100 psi there were no leaks or excessive deflection, and the balance of the parts are rated at 150psi or above, so I'm proceeding to assemble the first prototype.
We continued with pneumatically operated automatic valves for explosion proofing, and they have also arrived.
The electronics are ready to mount in an enclosure and we made some upgrades, using an Arduino board to allow us to use a absolute pressure (PSIA) transducer to control the cycles, vis a vis three adjustable vacuum switches, as well as a read out announcing what is going on with the machine at that moment, instead of just indicator lights. That also allows us to more easily change the program parameters using the computer and software.
I'm picking up the 1 1/2" 16 gauge 304SS tubing for the roll around frame this morning, which is the last big chunk. Here are some prints, as well as a picture of the Mk V body components, without the valving:
I made some changes in the Mk V frame, so now it also supports the pumps and ancillaries. Here are a couple of pictures of it and its 304SS frame in final assembly.
All the machined brackets are made, so next we will hang the automated valves, so that we can start plumbing.
Well, the first manual Mk V beta test sled was delivered and automatic is due completion next week. Here is a picture that the proud new owner sent of his second run, yielding 277 grams, or just over 12% on mixed trim.
