The Mk III Terpenator

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:

Here is a preview treat of the Mk IV layout mockup, which also has parts out for machining”

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, 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.

12-14-12

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.

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 info@caresaverusa.com, 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

      with the mark 111 i just dip a couple times into 65- 72 f during the dump of each column .. in the 12 ‘ i actually add 65-72 f water to bottom holding rubbermaid (cant find a big enough soup warmer yet lol ) during dump then suck it back out for next column ..

        • Posted by KillaVolt on August 11, 2014 at 6:52 PM

          Everclear/ethanol is not used for the initial purge, at least not under pressure. If you have a 100# recovery tank then that is for butane gas. After you have extracted with butane and boiled it off then you pour that BHO into ethanol and let sit in the freezer to extract waxes. after that you boil off the ethanol/everclear and bake to obtain winterized shatter……. please do not try to recover ethanol/everclear into a refrigerant recovery tank.

    Hi All,

    Long time terp-er here, but over the last 3 runs I have run into an issue. I am getting extract traveling up my reclaim port and depositing in my SS cross, 3/8″ ball valve, and reclaim hose.

    I haven’t changed up the procedure that I know of, and have experienced this with two different recovery pumps, one being the Appion. Has anyone had this issue come up before?

    Thanks,

    Are there any videos showing the complete operation of a Mk 3? I don’t fully understand the process of whats going on inside with the fill, drain, wash. Basically I’d like to know the flow of the fluid inside the unit.

    I understand it’s filled from the bottom up and then the top vent and fill valves are shut off….but then what?

    • Posted by Clay on July 28, 2014 at 5:19 PM

      The flow is. Cycle one two and three r from bottom up thru material. Then last is from overflow down thru material and then opening main dump valve empties all product into bottom vessel. Hope this helps.

    Have you found a Teflon or BUNA-N Butterfly Valve Seat to replace the EPDM Seat that comes in it?

    By not replacing it, you are introducing rubber into the butane, same as with silicone. I am concerned about this with ALL closed-loop systems as every Butterfly valve is made with rubber as the standard.

    Glacier Tanks only sells EPDM & Silicon replacements. I’ve been looking all over to find a suitable replacement with no luck.

    hello all, i have finished my experimenting in oil, and have 3 of both the mark iii and v (w/ 1 3′ section, not 2×2) setups, along with literally 10-20 of every part needed to make either (reducers, endcaps with npt, 6 or 12 spools, etc). i won’t be selling the appions because of concerns and problems with used ones. if anyone is interested in buying please contact me at terpenatorparts@gmail.com, i know glacier is sold out pretty much 24/7 so hopefully this brings parts to those who need them. i also have lots of improved parts (ie: 3/8 npt -1/4 flare, eliminating the need for bushings, etc) i can send pics.

  14. Been running my MKIII as a passive unit. Having done about 20 runs thus far. Got it dialed in passively. I use a 1.5″ dia x 4′ column. Easily holds a QP. I run it by attaching the solvent tank upside down on top of the column like a tamisium with the recovery pot chilled at or below 26° ice salt bath. To transfer the butane back I set the recovery pot at 160°F and the storage tank at or below 26°F or less using a thermo gun for verification. I get almost 100% recovery after 24hrs. I am able to set it and come back the next day weigh my tank and its on or -.1 lb. Problem is, with that size column comes a good size pool ol’ oil in the bottom of the 6″ dia tank. Takes awhile to recover and it will not complete it in said 24hrs if the recovery pot is under 160°F. I tried it at 120°F and no dice. Only about 66% butane transfer after 24hrs. Also tried different ice melters for better cooling effect on storage tank but then the ice doesn’t last long enough. I am impressed with this setup because I can make loads of honey oil passively. Hopefully this info will help others. Now I want to make shatter which needs lower recovery temps. GW, do you still recommend the Appion G5 as the pump of choice for the MKIII as far as durability in its price range? Or something different? I am trying to have the setup maintenance free as possible. Thanks to SkunkPharm, making some fine oil in Michigan for some fine folks :-)

    I think I’ve got some moisture build up in my recovery tank. I’m currently running my mkIIIA with a Ek-032 mf on the incoming butane line. I’d like to put another filter before the appion pump. What would you recommend, and how often do you replace these?

    Hey SPR,

    Is it possible to purchase a MK3 prebuilt? I think I will have a difficult time trying to assemble one myself.

    Thanks!

  17. Appion G5 ? = When doing the seal rebuild is there another source for the hard plastic seal on the piston? The one that goes over the 0 ring on the piston. I ruined one trying to get it on the piston and would like to not have to buy a whole new kit just for one of the hard plastic seals. thanks as always. stay warm friends.

    Hey SPR,
    I wanted to start by thanking you for all the information you have shared. I went and read every question and response on this post, but have not found my question asked yet. I’ve finished putting together my MKIIIa and have done three runs now, but my end product keeps coming out very dark, almost black. I am using a thermometer in the soup warmer and H2O temps start around 80° F, climb to 95ish then drop to mid-40s on final purge. Do you guys use anything below your collection pot so that it is not sitting directly on the soup warmer? I have a feeling that the H2O may be around the 80’s but the metal is hotter.
    Thanks for everything!!

    • For blonde shatter, we set the Mk III beside the soup pot, and only occasionally dip it in it to de-ice the lower end so we can what level the puddle is at. That takes the internal temperature to 25/50 degrees below zero.

    • Most of the time when I see oil come out dark or black when the temps are in range is due to several factors in my experience.

      1- If the starting material has been ground up. Don’t grind your material. Check out GW’s “Nug Buster” for the best size.

      2- Some strains are very dark. This is rare, but some strains produce a dark product vs. a blonde product.

      3- Old material that was decarboxylated due to poor storage conditions.

        I agree temperatures and age are the cause of the dark color but is blonde oil better. I think not, I am really enjoying extractions from 30 day old material. After I learned how to make the blonde stuff I realized I did not like it. I know everyone wants blonde oil but i prefer extractions from aged material. Call me crazy.

    We are having further problems with valve leakage. This time, we are seeing small bits of oil coming out of the large 1.5″ ball valve (#3), or the “dump valve”. This is on top of having major issues with butane leakage from the normal valves, even when they are new. Have you seen this issue with the large dump valve before? What do you recommend to fix the issue, replacing the valve or cleaning it out?

    • I infer that we are talking about leaks at the valve stem, in which case I have seen leaks at the stems on both types as received and pressure tested, but except for one occasion, was able to seal it by simply tightening the packing gland nut. On that occasion, it was the large three piece dump valve from Glacier, and I returned it.

      I’ve also seen valve packing wear out, requiring repacking or valve replacement. The one piece valves are under $20 each from Paramount Supply, so we just replace them, and the whole reason for the more expensive three piece valve, is that complete rebuild kits are available for them.

      Have you taken the handles off all the valves and tightened the packing gland nut yet?

    • I’ve had this happen with the 3/8″ and 1/4″ WOG valves from paramount. Tightening the packing gland nut on the valve did the trick.

      I would recommend taking the large sanitary dump valve apart and cleaning it with acetone and > 90% isopropyl rubbing alcohol. The packing glands are made of Teflon and the entire assembly is rather easy to clean and put back together.

    I have a brand new never used Mk 3 Terpenator with a extra tube and tank, all hoses, fittings, recovery tank & pumps, soup warmer, this is a full set up all you need is material to run and we have that as well. Every thing is new but the vacuum pump but it is only a year old with very little use. We have decided to go another way. Email me for details…Cash only..email ssoma151@gmail.com

    Hi Guys,

    We have had a lot of luck extracting dry material at about 150g per 1.5″x24″ column. However, in switching over to processing fresh, frozen material we have experienced column blockage at packing densities over ~175g per column. Symptoms include low gauge pressure during floods and short recovery times. The coffee filters at the top of the tube seem to become saturated with water and act as a barrier to the butane.

    Is standing water on our fresh material causing these filters to wet? Are we at risk of dissolving any water into our butane at this operating temperature? We have been taking the vacuum bags out of the freezer and allowing the material to dry to the touch before packing, or so we think.

    We did a test without coffee filters and were able to see more traditional pressure readings for flood cycles with ~20F butane (~15psi), but of course a little bit of debris made it to the recovery pot.

    How much fresh material do you all normally get in a column of this size?

  22. n last on the column heast question is , Is this stuff comparable to the tape from Platt ?

  23. Is this the animal you recomend or is there another “controller part ” not in this setup I would need to make it work on a 24″ column? thanks again. I’m trying to get over this “damn it s cold out” hump as quick as I can.
