CO2 Cascade Project **Quest for -100° C**

[Zork]

Wow man, awsome work so far.. Cant wait to see this thing in action... I see -100C in the future for you, real soon future..

 

[stockhatch]

Thanks Its good to get compliments from a skilled phaser such as yourself. I hope I see some temps soon. I was making a list of all the thngs it needs to be finished and it is alot longer than I first thought.

evap, flexible suction, gauges, wiring, charging, insulation, tuning, tuning, tuning.....

Dude, this is awesome. Great pics. How big is everything? Can you give us some pics with something to compare it to (the CD one was good, more like that!). I've never dealt with stuff like this before...all the terms and abbriviations are confusing me...but it still rocks nevertheless! GL!

Thanks. As far as sizing, here is a pic of the cascade with a motherboard on top of the IHX box. Its a blurry pic, but maybe it gives you an idea.

Very nice dude. Keep up the good work. You ppl with these kinds of skills make me sick

 

[d94]

sick stuff
imma deffinetly keep an eye on thsi thread

 

[CCUABIDExORxDIE]

that thing is HUGE! ima keep a big old eye on this thread. i like the looks of it so far.

 

[GQBalla]

wow cool! i subsrcibed to this thread!

pretty cool stuff

Lookin good sir, those rataries should do the trick for sure. I have a single stage with a 1HP and while it's a loud SOB, the temps are unbeatable.

Here's to reaching -100°

 

[stockhatch]

More progress. Gauges are fitted though not hooked up. Progress is slow as I dont have alot of energy after work...

Nice, I really like that look! Those guages are so cool.

 

[Alchemy1]

Wow, it looks nice, but that thing is HUGE!!! Good luck...I'll be keeping an eye out for progress reports.

Okay. A little update. Today I brazed in all of the second stage that I could. I am missing the flexible suction still, but the high side is pretty much ready. I sealed up stage II, pulled a vac on it and charged stage I again. The IHX gets down to temp much better since it is insulated. It hits ~-42 in ~-43 out with ease. I think once I do the final tune it should have no prob condensing the second stage.

 

[lclark2074]

good luck and maby a third stage like agon hehe but that was my dream awile ago

 

[Vio1]

any new progress? Awesome project!

 

[jcw122]

Wow what a project! Good luck dude!

 

[xTrEmEoVrClOcKr]

Whoa, havn't checked out this project for awhile! A lot of progress man, GJ!

Did you make that coil evap on your own or buy it somewhere? It's pretty close to what we use for HX on our liquid cooled FCB machines, and what I'm using on a couple of my chillers, except the ones I have, have larger diam for the water and 3/8 gas line.

Ive always wanted to build one of these, and knowing me, i one day will. My only reservation is that i dont know much of how it all works. How did you learn enough to build something like this? I understand the principle behind a 1 stage cooler (i had a Vapochill ls), but even then, i wouldnt know where to begin in making one.... i always imagine that something will blow up in my face, working with refrigerator components.

Did you take some kind of fridge repair course or something? How do you know what lengths of pipes to use, what component goes to what? How much pressure, etc, etc?

 

[SNieX]

soo tru.. like where do u constuct this stuff,,, i've always wanted to know.. how to build the piece that goes from the unit all the way to the CPU/GPU... (the tube and the plate)
like where do u start

It just takes a lot of research and hands on experience. A lot of tweaking and some instinct. Talk to people who do know what they're doing and familiarize yourself with terms and components. It doesn't hurt to know the basic principles of phase change either. A lot of it is math, but once you know what your doing you just get a feel for it. And most of all it takes time.
