View Full Version : ECI 33+ (3 Stage Cascade Worklog)
Here is the project log for my current refrigeration project. A 3 stage cascade for benching CPU's to their very max at the flick of a switch, no liquid nitrogen around here. Better. Adjustable STABLE temperatures without pouring or filling.

Maybe more to come? Who knows who might want to see their product get frozen over.
I joined (followed Buckeye actually) to share with you guys some current phase projects.
Hope you don't mind! :wave:
So here's some autocad!
Estimated Temperature: ;) <-- Ha like I'd tell you that ;)

UPDATE JUNE12th.
Little update.
Got home today, gotta start unpacking a huge amount of stuff from school. But, ran down stairs, and threw some crap on the table.
Hope you enjoy.

A milling machine! Richard got it into the workshop on this dolley of his. I was scared watching this thing jump up and down with each step. (Had to underinflate the tires on the dolley to take 300lbs safely)
Welding up a new work table, mainly for the project, but also for the milling machine.
Then we can start plotting the cage :)

Winch + ceiling beam = Mill on Table!
I'm happy it made it, table seems more then okay, but conducts vibration a bit much.
Going to get some more MDF under it, get it all bolted down. And then figure out why the spindle ain't spinnin!

Everything moved over, so time to start laying out parts.
Might have a lead on the condenser I'd like for this, so the front is a little empty.
Compressors that seem "used" are working pulls from my own personal cascade that well, I built and never got around to finishing. So they're brand new still.
Layout time.
Brazed the first suction stem on compressor numero uno. It's nice to do them like this, since they'll shoot straight up to the heat exchanger coils. Nice and easy to insulate.

It's Nice Pics NoL
Good Work Men Let's Some pic More
Let me explain this picture a bit.
It's fairly hard to shove one tube inside another tube. It's especially hard as the lengths required get long and longer. When making a heat exchanger using 3/16 and 3/8" tube, it becomes an exercise in insanity.
Both tubes must be nearly perfectly straight.
That means, even the tinyiest imperfections become a problem. As you begin to push one through, friction becomes a huge problem. Even a degree or two at a tiny spot pushes parts of the tube against the inside of the other tube.
This isn't a problem with performance, simply that it becomes impossible to push one tube in any farther. You must then withdraw it, figure out what's stopping you, touch it a tiny little bit, and try again.
My method involves 5 ft long steel beams and clamps.
Clamp the tubes straight as possible.
And try.
When your looking down a 20ft long barrel though, things get interesting.
This took 3 days.

And bent on up.
20" by 12". 4 loops or so tall.
Should be adequate heat exchange. And nice and easy to insulate, I hope.

I'm MIG welding up a frame actually. Starting on it tonight,
Second heat exchanger rolled, CPEV's tested played. Nice and up front. They will be "separately" insulated in their own little sealed box.
Now thats sexy. And under 3 inches tall.

Nice work NoL, so your shooting for temps around -130 but with better load handling?
Buckeye
07-07-2009, 05:33 AM
I would suspect after reading about your other 3 stage and the amonut of load that one could hold it would be some where in the range of -130c unloaded and below -100c fully loaded.
I don't remember what loads were used in that past 3 stager tho.
I would like to see a load handling ability of 300watts or more to be able to handle the high heat loads of Core I7 chips.
From my tests with my 920 D0 and LN2 I was able to take my chip to -130c and was still able to boot at that with a 5.3ghz over clock and vcore of 1.575.
How ever the sweet spot for this chip was in the range of -90c to -110c and did not find a real use of going lower for high OC's.
How ever with other chips this might be different.
Also AMD chips would love the extra cold and lower temps are better with them.
My thoughts on single or multi stage units is to go for max load temps and generally try for higher load handling ability as you never really know what chips you will put this on later.
From what I understand about these units is a low unloaded temp is not allways the best for handling loads. Better tuning of units will result in better load handling vs lower unloaded temps.
That stack is looking very nice tho NOL, good work !

Thanks for the clarification buckeye :thumbsup: Im no phase expert (I prefer LN2) I just remembered seeing sdumpers cascade at -130 coldbugging everything it touched lol.
I would eventually like to get a nice 2 stager but costs are very prohibitive for me. I got a wife n kids (hungry kids!) to feed. :pile: (thats a pile of kids to feed)

Yeah I read that also about cold bugs. Different chips do different things, my 920 can boot at -130c under LN2 but some others do not have that luck.
I don't remember if that first 3 stager had a hot gas bypass on it. I think those are really needed for these things.
On mine if I start getting CB's with other chips I have to shut down the 2nd stage and wait until pressure has equalized on the 2nd stage before firing it back up. Usually what will happen after I shut it down is temps will slowly start getting warmer and about the time pressure has equalized I am good to go to fire it back up again.
Before I do fire it back up I start the compuer so I am in windows before I reach max temps. It's a pain to do tho. but workable.
Oh yes. Sdumpers unloaded towards -150C. Coldbugged motherboards and RAM too ;)
The CPEV on all stages will allow a certian amount of dialing in of the temperature. Unloaded might be below -150C with the valve closed, but real useful tuning around -125C at i7 loads is a good goal. It will have a hot gas bypass as well for expressedly warm situations, and a controller on that to actually have it control a temperature automatically.

I really like that -125c loaded Core I7 temp tho ;)
With a setup like that you really would not need LN2 for 90% of benching, except for newer AMD chips that it. But very useful for getting everything setup and tuned before going to LN2 :)
And for that you could still dial her down colder for lighter loads. Not much use past quick Pi and such, but still not bad ;) The mass I'm delivering in the evaporator should be interesting.
Let's just say it competes with many top end ln2 pots.
Though finding the condenser I want is starting to become harder and harder.
Might have to shell out some serious cash to someone in Euroland.

I dream of the day I have a cascade setup. :this:
They're pricey, but if you bench Ln2 on CPU only 20 times, you've paid more.
karmakazi
07-08-2009, 08:38 AM
Not with the rates I pay for LN2 :D ($0.50/Liter)
So $25 for 50L.
$300 for a CPU pot.
$400 for a dewar.
How many runs to hit $1600? ;)
28?
Buckeye
07-08-2009, 09:49 AM
I prolly have just about paid for my Cascade in teh amount of use i get out of it, almost everyday its running which I could not do with LN2. I save that for chips that can really use it and for GPU's when I run them.
To say nothing about ease of use. You can walk away and do others things when the MonstaCade is running and not have to worry about the pot running dry. Being able to take your time in tweaking is also a big plus.
It has not taken away my need for LN2 to tho, just made things much easyer.
How ever, colder is better :)
Exactly. I hate rushed tweaking.
Here it costs you no real cash but electricity to play around.
Update for you later boys. Going to start cutting and measuring steel, and pressure testing the heat exchangers, AND creating the big massive pink box of doom!
Pink time!
Those CPEV's are looking beastley aren't they?

Kool, what do they do?
CPEV's allow adjustment of the suction pressure via the screw on the front.
In short, as suction pressure changes, so does evaporation temperature. Thus I can control the evaporation temperature of EACH stage!
Kal-EL
07-08-2009, 05:34 PM
Left loosy, righty tighty? Which way is colder/hotter?
Frick if I know. Probably righty tighty brings the screw into the body, more pressure on the screw, and pressure goes up? Pretty easy to test when its running. Normally they're set at 5-10psi to start. Even if its set at max of 55psi low side, it won't make a difference.
I think I went a bit overboard height wise. Don't need that much! (Yay the cascade just got shorter!) I think I'll shave 2 inches off of her. Having the "low" HX in the center helps with the insulation of it. Normally -80 to -90C would require 3" of foam.

Hahaha bug away, I think I'm almost done for the night. Cutting down that foam. Add some tube insulation inside the box, some tapering nails to hold it together, then break out some duct tape for an air tight seal. Maybe autocad the cage up. Keep your eyes peeled!
5 of 6 gauge kits.
2 ft of 1/8" tube on each, after brazing in an inch and a half of 1/4" tube to a tube adapator.
Will find that last bit or just pickup another while I'm at homedepot getting JB Weld for these joints. I don't like teflon tape, it's just not robust enough for me.

Im not trying to derail your thread but how much wattage does the monstacade draw at load?
I bet electrical costs top $100/month to run it. I prefer to tweak on air cooling b4 I go ln2.
I think for the temp control ln2 is a better bet anyday over a cascade, just my opinion tho.
Here my breakdown:
$25 per dewar fill (lasts me ~3 weeks)
$200 - 50l taylor wharton
$300 - F1EE which can be updated to fit any socket for just a couple dollars for a new holddown/backplate
So I assume that for $1600 the mostercade/something similar could be had? I would need to fill my dewar ~50 times to equal the original cost. not including electrical usage each month to run that monster. 50 dewar fills = 150 weeks or almost 3 years of running ln2. in 3 years i bet the monstacade needs a regas and retune. that isnt free either...
Just my $.02
Buckeye
07-09-2009, 05:14 AM
You make some good points there Karm.
Basiclly it boils down to trade offs on how you want to run your bench.
For me LN2 is 100% the way to go, but so often there is a catch to using it for me. Having to go out and get the Dewar filled and get scalpped by Airgas, I really need to put some foot work down and find a better LN2 supplier. Setting aside time where I won't be interrupted. All that and the Dewar gets empty all to fast LOL !
My Cascade uses two normal power plugs, 1 for each stage, I assume a 3 stage would need 3. Some homes/appts may have a problem running a machine like these and pop fuses or breakers.
Power costs might be an issue also, but I do not run mine 24/7 and perhaps 3-4 hours at a time. At my place the swimming pool pump is the biggest power draw. But you never really know because you can run the machine for very long periods and don't see the cost until the end of the month, and that could be OUCH ! if not careful.
If you could get a deal where having a large Dewar delivered to your home every month that might be prefered, where I am at thats not all that easy to do. But a carefully planned bench session and that would be a go.
Being able to dial in your temps with LN2 is also perfered, with mine unit its -111.7c unloaded and thats it. And also dealing with cold bugs is np with LN2 but could be a huge pain with Cascade, you can't just take a blow dryer to warm up the pot.
So in the end it's all about trade offs. For me it's convience of using the Cascade and ease of use. I use it more becasue I can simply turn it on and away I go, then off and I am done. Never worry about phone calls or having to do something around the house while in the middle of a bench run.
Does it mean I am done with LN2, far from it. I can just get in more benching with the Cascade now at temps that I want to run at.
I highly doubt that this Cascade will ever need a recharge or retune, it is built very well. Things like these don't need recharges unless you have a leak. This has held up for 3 years so far with no leaks so I think it can last longer with out a problem. Retuning a unit like this is not really needed, unless I decided that I want to go for a higher load capability. But I don't really see a need for that anytime soon.
To me it's all about the quality of the build and the steps the builder has taking to make sure things will run smooth for a long time. Good brazing and extended leak/pressure testing are all good signs.
If you ever get a chance to see this unit up close you will understand what I mean about quality of the build. I have seen other units built in a weekend and hardly leak or pressure checked at all, poor looking brazes which looks like nothing but trouble imo., better live close to that guy because you may need to go see him again :)

That dewar fill can't be lasting 3 weeks if your benching. You can kill 50L in an afternoon pretty quick with a quad and a video card. Also, you've got an amazing price at .50$ a liter, most people pay 2-3$.
And having an ADJUSTABLE cascade means it won't ever need a retune unless the world goes insane, and intel isn't going to produce a 9000W chip again anytime soon (the 840EE was never that popular past being a space heater after all!)
Having proper features from the beginning, like a hot gas bypass, allows you to have massive range of temperature control as well.

I know Airgas here in Oklahoma puts a $10 extra charge on small amounts of DICE. They told me that it is to get the average Joe Blow to go buy it out of grocery stores, I guess. How much is the charge on LN2 Buckeye?
Gauge prep! 6 lines made up, two lines for the hot gas bypass solenoid done as well.
JB Weld time, that will take the rest of the night to dry. Then will begin to pressure test components.

When I take my 50L over to Airgas they charge me $125 and that includes a Hazmat charge and what not.
Do those guages up real nice there NOL, so they don't end up looking like spaghetti flopping all over the place <cough> like another I have seen ;)
It's starting to look real good :)
Even the pink insulation for the guys wearing confortable shoes ;)
I'm trying to size it all up right now, you know, make it come together.
If I want to have the big electronic box on the back but within the case, I think 32" long, 18" wide, and 20" tall is going to happen.
But If move the electronics out the back, I have easier housing for the expansion tanks.
Hmmm what to do.
Compressors and what not can't really move. Oil separators are fairly large.
See what happens when you don't autocad EVERYTHING? ;)
Meh I've got an idea.
Time to start drilling holes in a big mdf board.
When I take my 50L over to Airgas they charge me $125 and that includes a Hazmat charge and what not.

How long will 50L take you on just a CPU pot.

It aint cheap, but I'll say "Its EASY!" turn on switch, bench all u want, tune in clocks, turn off. Now run off to get some ln2 to see what else you can muster from it. In the end, it all costs more than an un-addicted person could stomach. :shock:

07-10-2009, 09:05 AM
I think its cool to see others approaches. I wasnt criticizing or anything NoL.
For me LN2 is just cheaper, easier, and better. If I could make a good cascade or have one built at a reasonable price I would. But neither of those things is gonna happen ;)
Hey its the classic OC'ing arguement. Cascade or Disposable (Dryice/Ln2), cascade is just a long term investment.
Extra insulation bolstering the HX box, pushed finishing nails through, holds the walls in, and lined all the holes with nice black duct tape. That'll seal it up before I spray it with foam later on.
Now to do some welding work.

So is that pink box insulating the pipe so you dont have to insulate it w/ pipe wrap?
Sort of.
They're really won't be much piper wrap here.
By using this box though, not only are my heat exchangers nicely insulated, but they'res no real runs of cold pipe other then the direct suctions up from the compressors.
Also, the first heat exchanger is helping insulate the second, and never leaving the box means minimal heat losses.

Obviously I haven't touched this in a while. Had shoulder surgery and medical school keeps you low on time. So back to work on it.
Today I finished the base, swapped first and second stage to new QK191CAB compressors (1hp), and made mounting brackets for every part.
Also got some brazing done.

Guess this thing is gonna be permanently mounted on that table? Looks beastly heavy.
Hey a little update; she's all brazed up except the flex and evaporator (still need to decide who's Evap is going on this!). So I began to pressure test the first stage.
I hooked up my N2 to the high side schrader and slowly increase the pressure.
Then something odd happened.
I'm checking my gauges on the front of this thing, and the high side one rises, but the low doesnt. So I figured I had a bad CPEV. Then I realized what it was.
The CPEV was set at 0psi.
So it was locking out the N2 flow.
With a laugh I opened up the CPEV and ta-da pressure on the low side. Fun to be able to adjust it all over. Can pop out the schrader on the low side and make N2 do whatever pressure I'd like. Like a miny regulator! :)

NOL this build is looking amazingly neat and tidy for the amount of copper that's going into it. How the hell do you find time for med school and to still build this stuff? :Dizzy:

What I like is hes doing this build totally different than the knock offs that are going around.
Yes its taking NOL awhile to build this, but these are not simple builds and take time and money + knowledge to complete a good performing and safe unit to run. Plus he has school etc that he also does.
Good Job NOL !

Funny because my cascade still doesnt work properly from him.
Take your issue elsewhere Planet, we already resolved our dispute. Crash someone elses party.
I shall name it Squishy, and it shall be my squishy!
Run caps and R507 decided to show up (that cylinder took 3 weeks to get here from Hawaii, but brand new for $85 was hard to pass up).
So what did I do? Checked my micron gauge, and after a week sitting, she still read 185 microns. Amazing; that meant charging time.
A burst of r290 (brought up to 20psi) to handle the oil, and then flipped to r507a. After I had maxed out the CPEV, I realized I was getting little adjust-ability, the rotary is just huge and doing it's job. More charge and I got adjust-ability back. I hit critical charge and the temperature started dropping. At four minutes the back end of the goal had snow. And six, it was all nice ball. By eight minutes the accumulator was showing signs of blizzard conditions.
She has a nice purr to her too, vibrating against the table it's on isn't helping but the 1/3hp thing on the condenser is working. The first coils are warm if a bit hot, but by coil loop two it's only 2C over ambient. That will change with load, but I doubt by much.
Onto the sexy pictures.
