G5 down

G5 down

Did a run recently with two MKIII's running off one G5 with two tanks, also ran them both on one vacuum. Worked great and the tanks were filled evenly, I weighed them before and after to be sure. Seemed like it wasnt any slower than normal as I was running a third MKIII next to them and they all finished simultaneously. The reason for the trial was I had a G5 go down during a run. I had to switch G5's and attach to the vac line to clear it out. The G5 sounded like a car crash when it went out. I instantly shut it down, heart racing lol.
a pressure test after the fact revealed it will no longer reach the pressure cut off...

High Life,

Not at the moment. I had mine break during a gasket replacement. It broke so easy I must admit I am a little concerned. It was a bit stuck to the buna gasket, which was breaking down btw. As I pulled the glass off the gasket it broke in my hands. I was a bit surprised how easy it went for being Boro and so thick. So I have found a better option for peeping the action. Fused stainless and glass that will not fail, or so they say... A bit more spendy but for the promise of never failing Ill take it. It is much smaller and attaches to a triclamp port, ie an instrument arm and you can even get them with explosion proof lighting options... hit me up if you are interested.


On another note I have noticed my buna gaskets giving off a black residue when I wipe them down. A friend who has attended the SP classes mentioned GW said that they will breakdown if you clean them with alcohol, which I do regularly. So I switched to Viton for all my gaskets. I have a fresh pack of buna that I will finish off first. changing them frequently is key .... Maybe GW can elaborate..

Check out the comparison between the g5 and cps.

While I honestly am not certian it applies I was suprised that the g5's rating for recovering "r22 vapors at 75 deg" is higher that the cps...

Do any of you cordial intellects have insight as to what ratings (if any) might apply on the search for superior recovery?

Really interested to hear back from the shootout GW, keep us posted.

Yeah, Buna N is suitable for butane, but not alcohol, which we use a lot of for cleanup, so we switched to Viton, which is suitable for both.

 

[Momerath]

Momerath,

dont pour butane on silicone, they are not compatible and silicone will break down and contaminate your oil. I was also reading were graywolf mentioned how certain terpenes will strip paint off of things. One terpene mentioned that is not compatible was pinene. Im going to quit using it just to be safe. A quick google Im sure will turn up some info...



I do not see a link GW...?


FE

I agree, silicone plus butane is a big no-no. However, the Oil Slick guys make a product called a Slick Sheet. It is an 18" x 48" roll of PTFE film, not silicone. PTFE is rated to be fine with butane, so it should work just fine with the pour out.

[Momerath]

Also noticed the same thing with my Buna gaskets, they give off a little black residue when wiped with iso. Will be switching to all Viton gaskets.

 

[FatherEarth]

AhhhHAaaa! PTFE... wish it wasnt disposable but nice indeed. thanks for the link.

 

[Momerath]

Disposable, yeah, but I figured that's 4 large pyrex pan size pieces for 25 bucks. Pays for itself and can probably be reused at least once or twice if handled gently. When it gets here I will let y'all know how well it performs.

 

[A6 Grower]

PTFE may be fine for butane but the terp issue fe brought up is something to ponder. Terps stripping paint!?! Thats crazy lol. Glass everything in my lab. Need to try to the pour out method sounds nice.

 

[Holden Oversoul]

Has anyone tried [URL="http://www.bedbathandbeyond.com/store/product/chef-39-s-planet-non-stick-oven-liner/1013037604"one of these?[/URL] It's a PTFE oven liner and it looks to be more durable than the slick sheets. Measures 23" x 16 1/4" x 2/5" thick and is made in the USA.

They also sell the slick paper. I've purchased it in the store before,it comes in a roll box like parchment. I can't find it on their website.

Sorry to double post but I can't figure out how to edit my previous message to fix the bad HTML. Hope I didn't typo this time.

sight glass

just put my Mkthree together and I was interested in the new link for the new sight glass you just posted. Tried to pm you but new to this forum could find the link. Hats off to you for starting this thread and sharing information. Peace to all !

 

[FatherEarth]

I didnt post a link to the new sight glass... I previously posted the one from brewershardware.com which has been pillaged and plundered for anything that fits the MKIII.

 

[FatherEarth]

Search for Metaglas thats the name you want...

I am working on getting to a completely scrape-free tech. Its always just messy and wasteful. In the next couple days I got a cool new slick sheet coming that I will be combining with the pour out method, low heat purge and then right into the vac, scrape and agitation free!

Was also thinking the same thing on the spout for the collection vessel. Just gonna install a little spigot so I can just drain off the butane/oil without opening the whole system. I am dreaming of a MKV with a spout that, when opened, flows a most beautiful stream of golden goodness right into a lovingly prepared pyrex.

I was thinking of a port to connect a purging/finishing vessel via tri clamp that I could connect a vacuum pump to. I would connect the purge vessel, pull a deep vacuum, then open the drain to pull all the oil laden butane in and then close it so I can do this without worry of butane escaping. Then connect that to a recovery pump recover, vac down ...etc

maybe we should have an open source extractor thread where we throw ideas in to come up with an ultimate design...

 

[RegisPhilburn1]

FE i was thinking of setting up the same thing, But i would like to incorporate some sort of de-waxing technique. I was thinking that once you are ready to transfer between initial collection vessel to the secondary one you would super chill( Think dry ice towel wrap) the initial vessel to precipitate out the wax, then with the appion pulling on the second vessel, open up the connection between the two and pull the oil through a filter to dewax. And then recover the tane from the second vessel if you want.

It would be really nice to be able to dewax under vacuum for 3 reasons.
1. No pouring liquid butane in open atmosphere
2. No condensation from super chilling with dry ice.
3. The ability to dewax and recover all of your tane


You could also make the secondary vessel a much easier to scrape shape too.

 

[FatherEarth]

++ For not needing another solvent to winterize. A filter on the triclamp valve port would be easy too. I agree about the vessel, Im going to get away from the spool for my purge vessel Im going to see what I can have custom so its exactly how I want it...or at least until i try it and realize it needs something else. Im thinking rectangular and more shallow with a bottom you can remove like the spool. I want the equivalent to a triclamp seal with the removeable ends aspect just make it larger and not as deep as the collection pot...

 

[nakadashi]

Winterize it. Thats what this machine was originally designed for. I have recently switched to winterizing everything, as i noticed some metal shavings in my oil from trying to scrape the spools. Stainless on stainless scraping will eventually lead to shavings for sure. So its pretty much pour liquid butane out or pour ethanol in for me now. And doing the winterizing method i can get about 1.5 times as much extracted in a day since i dont need to go back and forth to the vac and scraping sucks. Then i just filter and purge the winterized stuff later in the week sometime. a big evap box like on SPR helps a lot.


If you do multiple columns you need to have heat the whole time. I only do 2 max, the oil gets everywhere in the pot though. You have to pull a vacuum in between columns to make up for the air that gets introduced while switching.

Uuh LOL i can't believe I never saw the evaporation chamber on SPR before, thanks for turning me on to this. Also when you use ethanol, at what stage are you adding it in, and at what quantity?

Is it actually possible to achieve true winterization without use of a second solvent? I was under the impression that a polar solvent was strictly necessary for the precipitation of plant waxes. Have you guys tried doing an alcohol winterization of dry ice run before? I did once and actually was able to precipitate more waxes out of the EtOH solution but I was not sure if I performed the dry ice extraction correctly..

 

[icdog]

What happens if you don't cool down the tank with ice? If I run one column and flood 3 times does the tank need to be ice'd?
