Is this from some known authority?

There's some serious misinformation on that page. The "oil vein" pump bit is amusing.
It's on the intarwebs, so it must be true eh?

It is worth a read, but holy cow, how much slander, name calling, and "I'm the closed loop God and you are all my lesser copycats" can I take? Not much.. That's a waste of my time.

Too much "THIS IS HOW IT IS DONE PERIOD." when I can debate them easily.....handling live resin and moisture....use of 1/4" copper coils...
I skimmed it, but got caught up in this guy's fucking ego trip.

Yeah that's that Elliot Valentine or Jon Brown Valentine(or whatever his new name of the week is) guy from the closed loop group on Facebook. Everything you know he has thought of already and it won't work. Lots of run on sentences and poor grammar that makes my head hurt. I have a hard time taking people like him seriously. Seems to have quite a following though.

Im actually surprised but at the same time a lot I would argue with. Seems like he doesn't realize that there are plenty of people with custom CLS/tech that have no interest in sharing with the public... But damn imagine having that back in 2010...


Just realized thats a store. That 800$ "2-phase 1/4" super chiller stainless steel food grade" says a lot

should i go 50' for the injection and 25' after my TR21? both 3/8.

or should i do a 50' coil for both? re-read this thread a couple times but haven't seen to find a consensus...

 

[Obsidian]

1/4" is unsuitable for subzero butane, because of how high its viscosity gets.

We use 1/2" on our injection coils.

GW are you saying that his 1/4" inlet and outlet for the 3/8" coil is to small?
you mention you use 1/2".
my question...

should one use 3/8" recovery lines on the MKIII?

I use a 1/4" injection hose into the MKIII, and use 3/8 recovery line to a 3/8" coil that has 1/4" inlet and outlet, then 1/4" hose to the recovery tank.

I've noticed recovery issues when things get to cold, and my thoughts were the 1/4" ports are way to small.

uping the size to 3/8" ports and hoses would be better I'm guessing?

We used 3/8" coils from the brewing industry for our Mk III, and they worked fine. Since we pass more gas in the IV' and V's, we use 1/2".

Ok, so we run a 1/2" x 50' stainless coil in a ten gallon pot as a cooler coil post compression - essentially an IC69.

The IC69 pot has a 1/2" lower drain valve (for fluid, the gas is bulkheaded in and out of the pot else where) which is where we inject the cold fluid from sweaty Betty. At the top(side) of the pot is a 3/4" drain which returns to the sweaty Betty reservoir. A counterflow setup. Gas flows down and cooling fluid flows up.

So, we tore apart Betty and got her naked for the first time in her life.

Bending the evap out wasn't too hard, tried our best not to kink anything. As you can see, I'm using two 27 gallon HDX totes from Home Depot. There is enough room between the two for insulation. We used foam on the bottom, bubble foil on the sides and foam on the top, and a little spray foam everywhere.

Electrical was easy. Betty had a digital thermostat but we ditched that in favor of on/off switches. Plan on doing a better temp control setup soon, but for now this will work to prove the concept.

Just for testing purposes and because PG is so pricey and hard to come by in large quantities, we ended up using RV antifreeze. Already plan on switching out to PG/ETOH/H2O once we get her lined out.

Anyway, we had to build a skid to fit her on:

I don't have pics of the fluid supply and return setup, but it is fairly straightforward. A simple submersible pump that I had laying around from an unused aerocloners serves as the circulating pump, and vinyl hose for the lines.


So, once we got Betty all hooked up, filled, and circulating, we kicked her on. I think it took us about an hour to chill our 20 gal of antifreeze from 68f to 0, maybe less because we were kinda drinking around a little bit. Lowest temp I caught on camera was 1f.

Anyway, going to do a test run today with her and see how she compares to drowning dry ice in the IC69. Will report back with results.

Betty is loaded with r-22, btw, which boils at -41.6F. You may or may not have better or worse results using a Betty loaded with a different refrigerant. Just an FYI for y'all...

This is badass, I might have to do something like this now.

So, Swim finally scored an xtractor depot infinity tank with the internal coil and a second hand ice maker. Going to plumb the two together to make a giant immersion chiller. It may eliminate the need for a post compression heat exchanger. Will construct and report back!

Certainly delivered in the voice from Mt Olympus style, and starts off with class photography demonstrating his perspective.

Kool! How many BTU/Watts is the ice maker?

I believe it is a 2 hp compressor, not sure on btu's but IIRC I think 2hp = roughly 15000 btu/h

I'm going to our island of misfit toys to dig it out of the pile this afternoon so I'll have a solid number later.

That ought to be big enough!

Unfortunately I overestimated the size of my equipment, a common thing amongst us men sometimes.

I have a 3/4 hp condenser/compressor on the ice machine. We're still going to try it, but I think we'll need a condenser/comp doubt that size.

According to my very unreliable temp gun, we are shedding 60 degrees f from one side of our flat plate dischg HX to the other (90 degrees to 30 degrees f). We are accomplishing this using a 1/2hp 134a window shaker converted to a chiller, so this 3/4 hp 404a con/comp may be large enough. We will see this week, hopefully.
