Lmfao you know that's a great question!!! I have no idea but I have seen them in people's ovens before.

Lol I've never thought of that before! I imagine under vacuum an analog or a digital one that's not meant to be at vacuum may not perform well.

Good call bro, I have no idea. I bet you can find vacuum rated ones online somewhere.

Someone brought up mercury thermometers in my oven and I jumped right to hell no because even if the glass could handle vacuum the mercury would bust it from expansion right?

 

[Rotel]

I'm of the opinion that a spirit thermometer would be good to go. i'd put it by itself and see how it performed.

Mercury is pretty dense stuff. It's boiling point is 674F. If it was housed In thick enough class it might not explode. Try one and test it. Maybe vac seal it in a bag first.

Lol I hate converting Celsius to feranheit!

Me too, that was just the first thing that popped up on a search. Someone could surely dig up something in Fahrenheit.

So I was thinking, Do yall keep your AI ovens on 24/7? the first one I got to play with we shut off every time we were not using it, but AI told me when I went their that they are to stay on all the time. like, the next 5 years it could go without being shut off. the power it uses supposedly is so minimal vs turning the beast on every time i need to use it again... to an extent, but im sure you wouldnt have one if you used it that infrequently. anywho, comments?

Is anyone using the thermometer that have a probe at the end of a thin wire? The ones I have turn off after 30 or 45 mins and are inside the oven. Was seeing if anyone had used one like the one described with success I have doubts it would keep the seal on my vac.

We use thermocouples in the oven. Our Cascade TEK thermocouple wires are epoxy potted through the oven wall, and I stuck a 1/4" tubular through the wall of the Napco, using a 1/4" compression fitting, which I drilled through.

Depends on the range of the thermometer and how hot the oven was. No problem with the vacuum. Our mercury lab thermometer goes to 205C/400F.

Yup. Mine runs 24/7 with a bunch of slabs of granite inside. Nice and toasty warm

Im going to get 1/4 sheets of aluminum custom cut locally for like 11$ a pop. The ones they come with stock are only 1/16 inch and they try to charge 40$ a pop for them!

I'm wondering why we pay so much for devices that do such simple tasks? Is a vac oven really needed? You mean all this engineering going on and we can't come up with our own onboard purging system? I'm saying 9k for a vac oven and it doesn't even pull the vacuum just holds it and heats... Cascade Tek is clearly the better oven, but do we really need expensive machines that don't really hold much material anyway. My neighbor has two cascade tek ovens I'm familiar with them. But for me I know deep vacuum reduces quality via terpene loss. I do a quick initial deep vac at room temp then break vacuum and let the muffin fall remove while the oven heats up low heat 85- 90f vac down to 5-10hg and hold for about an hour and then only low heat with repeated flipping of the slab. Next day slab Comes out Stable as a coffee table with no waxing. All I'm suggesting is that we are spending lots of $$ for something we don't really need to imo. We can build something that should be able to deliver the same results.

 

[FatherEarth]

Wow! But really....? 100k.?

Have you tested your product for residuals after your purging technique?

 

[FatherEarth]

Yes, passes testing. No residual.

 

[A6 Grower]

It passes a 12 solvent test with <10ppm of all solvents? Hmmm ill have to try this

 

[Pangea]

Word, I drool over the 3 heated shelf 7.xcu.ft ovens, but for 7kish I think I can build 2 or 3 equal custom ovens.

 

[snake11]

Yes, passes testing. No residual.

This really surprises me as I have experimented a lot with time/temp while having our product tested. At the temps/vacuum and time you are using there was still solvent in our material. Our results are always below 10ppm however much higher vac and temp are used. What size runs are you doing?? Who do you test with?

 

[Dab Strudel]

It appears as though I got a bunk ass Elite oven. Its not heating right. top shelf hits over target temp and every shelf theirunder is between .75*c to 1.25*c off from one another. It is a shitty inconvenience but I gotta hand it to them. ive had it for about 2 weeks and all i said is its not working properly and she gave me options. I was impressed. I thought theyd give me the screws about it being my fault or something gimmiky but nope, they sent me a shipping lable and all i have to do is get a pallet, make a box and call the respective shipping company to pick her up. *sigh* I just thought of the woes of getting it off the truck, into the back... now i have to do it again........... oh, and again when the new one gets here.
