I was interested in the diablo at first, but I had a few people tell me to steer clear. Glad to hear it's working out for you. How is the speed compared to the appion?

Sweet brother. Welcome to the mag! See ya around

i just need to reiterate this point

warm vapor INTO appion, good or bad?

Thanks for all you input and designs in this research between SPR and ICMAG folks great info.

just for refference, a suggestion to run cold liquid tane through the pump rather than warm vapor

sorry im making such an issue out of this its just that i have seen not one person mention a pre-evap coil or the longetivity of a pump when doing so.

check the bottom right of the image for the coil in the hot bath, try not to jizz on yourself when you see the res of the pic

The warm coil is to insure that no liquid butane reaches the pump.

I haven't personally tried it, but I'll see if I can get Eloquentsolution to come on line and comment on how it's worked for her.

As points to consider, to turn it back to a liquid, you need to remove the heat that you just added. ES is using dry ice, so plan to do something similar.

It isn't liquid butane that is hard on pumps, it is the resin in the butane that glazes the cylinders and fries the seal. Not sure where that resin goes with the coil.

The core issue is of course, how did liquid make it all the way to the top of the lid and get ingested, and besides over filling, one answer is technique. Look at the underside of your lid after an extraction and see how messy it is.

With the pot under more than 14 pounds of vacuum and a soaking column warmed up to 30/45 psi, when you open a vent valve or the dump valve, it is best done gingerly until the pressure equalizes. Envision the two down tubes aimed at the puddle in the bottom and about the equivalent of up to 60 psi differential is suddenly released.

Because there is lots of vapor to pump at that point, the vapor velocity through the intake port is high, so liquid is also more likely to be captured. Under vacuum, there isn't much flying around to have velocity and capture droplets.

Since it has proven to be a sensitive area, we are adding an inlet deflector to the automated Mk V beta prototype.

We supply Haskel pumps on our turnkey systems, but for shits and giggles on alternatives anyone can choose to add instead, we moved to a two stage system on the manual Mk V beta prototype, starting with a diaphragm pump, which doesn't care if there is liquid present, and as it puts the vapors into a secondary tank first, the oil less recovery pump is less likely to see it.

I thought about doing this exact same thing, but my thought was it would still be adding pressure back to the system and i didn't know how that would effect things like pushing oil back up into the vapor line or something.

Seems that it shouldn't matter that the vapor is hot or cold with the appion, i think it just doesn't like running under a vacuum. so if your heating your vapor after the collection pot and adding some pressure for the appion i think this could have a good effect on longevity. I have my storage tank in a deep freeze with dry ice around it so there's little pressure on the out side of the appion to make it easier for the little guy. I run my MKIII with no heat or dipping the collection pot the entire time until the final recovery. This keeps my butane very calm and allows me to run more butane in the system to keep some pressure, with my tech and soak times and 3 passes my gauge never drops bellow zero while i run and only goes to -10 on my final recovery.

Is this working well for you? Did it have any effect on recovery time? how hot is the water?

Ive ran an appion for 8 months 40+ hours a week, by never letting it drop too far in negative(never go past -10 with it) and clearing it out of butane every night. Lots of tane stays in the machine, i unhook my inlet and let air in to push all the tane into the tank. I burp my tank once a week, or till i start to see more pressure in the tank when running. Stock seals and everything, Going to switch to PTFE seals when it starts leaking.

I Dont think this is as much of an issue because I'm pretty sure I'm going to wire up the gast system. It doesnt look too difficult and seems to be the way to go with electric pumps. Thank you for the input gray and A6

[A6 Grower]

ya the gast would be a better option but this could be a cheap addition that would extend the life of the recovery pump. Although the gast will be a bugatti, and the warm coil is like a souped up civic lol.

Ive only seen appions in action, never ran one. But the the person who I watched run with an appion thought my diablo was much quicker and quieter, but at the cost of running hot because it doesn't have those massive fans the appion does that make it so loud.
