Those of ya’ll who have been following our progress with the Mk I and II Terpenators, as well as the Lil Terp passive extractor and Enabler compound fractioning still, will be interested in our new Mk III Terpenator, based on the Lil Terp chassis.
This is just one more configuration possible with the Lil Terp tanks, simply by changing out the modified lids and bolting on readily available parts.
You will note that the collection tank is a simple 6″ X 6″ sanitary spool, with a standard end plate and clamp for both top and bottom. We laser cut and machined new bottoms for the first Lil Terp series, but that is not necessary starting with a 6″ spool. The top plate is the only piece in the whole assembly, that is not standard off the shelf at either Glacier Tank, or at Paramount Supply.
This picture is a mockup of both Lil Terp and Mk III Terpenator parts, but I will post the final assembly with the correct parts, when they arrive back from the machine shop and welder.
The column shown holds about two ounces, but the system will accept longer columns. Cycle time is unknown until we run trials with our prototype, but with the same sized pumps and smaller volumes, we are expecting it to be faster than the Mk I, which processes about half a pound per cycle.
Here is the lid maching detail. I’m also replacing the long Tee for butane injection, with a more petite one made from a short reducing spool and a 1/4″ 304SS nipple. I’ll post pictures when I get the pieces back from the machine shop:
Hee, hee, hee, the Mk III parts are back from the machine shop and ready to be welded.
Lu lu lu lu lu lu lu lu lu lu lu lu lu lu lu lu lu!!!!!!!!!!!!!!!!!!!!!1 It lives! The Mark III lives!
Hee, hee, hee, here is the purdy lady and her butane storage tank complete and ready for testing!
Lu lu lu lu lu lu lu lu lu lu lu lu, whoop, whoop, ahwhoooooooooooooooo!! Hee, hee, hee, snicker snark snort………………
The Mk III worked ran like a Formula I on the Appion twin, and actually beats the throughput of the Mk IA, albeit with a column change in the middle.
Not counting the first cleaner load running leaf, I ran five column loads, of three different strains and material grades, and they weighed from 135 to 200 grams, all packed in the same 1.5 X 24″ column.
The thing that is mind boggling after running the Mk IA, which will process about 470 grams per hour of prime bud, is that although the Mk III has a column capacity 33% less than MklIA, it processes it through the same number of cycles in 12 minutes. It therefore can run four cycles per hour, vis a vis the Mk IA’s about 25 minutes per cycle, or two cycles per hour.
That is not counting the 5 minutes hard soak at the end of a series of runs of the same strain, which both the Mk IA and III add on to a series, but not to each cycle.
The Mk IA processes about 470 grams in two 235 gram cycles, in the same amount of time that the Mk III processes about 600 grams in 4 cycles.
The Mk III is actually so fast using the Appion, that the pressure gauge on the first reclaim cycle, looks like the minute hand on the clock as it falls.
The second flood and recover cycle is not quite so fast, as more butane made it through the second cycle, and the third is of course the long one, because it is evaporating butane out of the now open column as well.
As I don’t have column heat on the Mk III test sled, the columns iced up on the last cycle, which was slooooow compared to the first two, so I will add column heat.
That was the only time available to stuff the next column, because the other cycles are happening too fast to not pay close attention.
Peak operating pressure in the Mk III ran about ten psi higher than the Mk IA, at 45/50 psi, compared to the Mk IA’s 35/45 psi. All well within the component pressure ratings.
The only thing that didn’t go very well, was my picture taking, with most of the equipment in mixed shadows under a tree, but got one that demonstrates the point. Alas no good oil shots, as the light wasn’t suitable for in the pot and we washed it out with ethanol for winterizing.
I promise to do better with the pictures next time and will report the yields after winterization is complete.
One thing that we did do, that departs from the original plan, is to use a 50# refrigerant recovery tank, instead of our fabricated one, to speed thing up with its greater condensing area and lower price.
Here is the parts list and costs. I will try to get a more finite breakdown on labor, with the next build. The total included building a storage tank as well and extra set up time for a single run, so ostensibly future labor will be less.

Progress has been made! I set up an aerospace quality manufacturing network to build Mk IIIA kits, and we licensed manufacture and distribution to Specialized Formulations, who now has a sample lot of five Mk IIIA lid and injection tee kits being machined and welded, to the latest design. http://specializedformulations.com/
The Mk IIIA design differs from the original Mk III, from the standpoint that the 3/8″ half coupling was replaced with a 3/8″ nipple and the cross assembly welded in place to clock it properly and eliminate two threaded joints.
The Mk IIIA design also incorporates a 6″ X 6″ sanitary spool for the lower tank, as opposed to splitting a 6″ X 12″ sanitary spool and welding on a new bottom. The new arrangement uses a tri-clamped end cap for a bottom, which costs less overall and allows easier cleaning.
The Mk IIIA can use either passive heat and cold techniques for recovery, or a refrigeration pump to reduce cycle time to less than 15 minutes, as with the Mk III.

Terpenator Operating Instructions
The Terpenator series are operated as follows:
1.0 Open all valves, except for valve #4, the butane supply valve.
2.0 Turn on high vacuum pump and pump system down to -29.5″Hg.
3.0 Close valves #1 and #3.
4.0 Turn off high vacuum pump and turn on the recovery pump.
5.0 Place one hand on the vent line exiting the top of the column and turn on valve #4.
6.0 When you feel the sudden chill of liquid butane reaching the vent tube, close valve #2, and then valve #4. Record the number of seconds required to flood the column with the existing packing density.
7.0 Continue to pump with the recovery pump, until the internal pressure is reduced to -10″Hg.
8.0 Open valve # 2 and valve # 4 for the same number of seconds that it took to flood the column the first time.
9.0 Close valve #2 and then #4 and continue to pump, until the system pressure is again reduced to -10″Hg.
10.0 Repeat steps #8 and #9 for as many cycles as you choose to run. Typically three cycles for the Mk IA and II, and five cycles for the faster Mk III and IIIA.
11.0 At the end of the last cycle, when the gauge hits -10″Hg, open valve #2 and then valve #3 to dump column.
12.0 Continue to pump until the system reaches -22″Hg, at which point close valve #5 and turn off the recovery pump.
13.0 Open valve #1, and turn on the high vacuum pump.
14.0 Pump the system down to -29.5″Hg and close valve #1.
15.0 Shut off the vacuum pump and allow the system to sit under hard vacuum for 5 minutes to purge.
16.0 Remove product from lower collection tank.
Heads up! Beta testing revealed one leaky lower dump valve thus far, and as there is no packing adjustment on the valve, we have replaced it with a three piece, adjustable and rebuildable 1″ ball valve, that sells for $69. The part number is BV2CV-100.
We bought the last ones Glacier Tank has in stock and new ones are out 8 weeks, so as an alternate, will use a Dixon three piece triclamp ball valve at $115 in the interiem. It is available from Paramount Supply as PN 115-BV 2 -GG-150-CC-A.
For those of ya’ll relying on the Mk II parts list for hoses, we have also replaced the 3/8″ recovery hose with one from RSD refrigeration supply. The hoses listed has undersized ports and substaintially increases recovery time.
Mk IIIA Terpenator Parts List
|1||Wyott RCW-11 Commercial soup pot||1|
|2||G-5 Appion Twin refrigerant recovery pump.||1|
|3/8||RSD refrigeration supply house 3/8″ X 5′ heavy duty charging hose||1||$37.55|
|50#||Refrigerant recovery tank||1|
Depending on what you are extracting the oil for, you can vary the recovery pot temperature from ambient to 212F. As the temperature increases, the oil becomes more decarboxylated and looser, and the plant sugars caramelize, darkening them.
Here is a picture of oil extracted at 85F, showing how blonde it starts out as carboxylic acid shatter.
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 marshals, but they are not oil less, so we don’t use them ourselves.
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
