wooh this is an incredible clean build, no doubt perfomance will be as high as the unit is clean, the most sharp builder around here bazx.

Those boxes are just painted fiberboard right?
Insualted and then with some PVC pipe for the copper and insualtion to pass over and inQuote:

Tim, this is a thermal static system, as such, placement is irrelevant as there will be a solid liquid coulomb to the valve no matter what as assured via the receiver.
If this where a cap tube system you'd have a snow balls chance in hell of having a leg to stand on, even then a correctly built system at running temp it is still irrelevant as to the F/Ds placement!
Very nice work. It looks like a sled :)
lol you spotted the wooden runners then:)Quote:

Beautiful, hard to top this build :clap:
Again very very nice, I particulary like your little mounts and stuff for holding stuff up. You make them urself?
shes coming alive, cant waits to see her frost bazx ;)
i specially like the flex suction lines, very clean :clap:
will you be able to close the whole unit? as I see the fiber board boxes coming a bit out of the metal sheet under..
lovely unit!!!
He said the unit is not going in case as he will be using to test a lot of kit
READ THE TOPICS PLEASE....ALL!!!!!!!
sorry dude, I spotted that part.. no need to answer like that.. same thing can be said in a better way and achieve the same objective :)Quote:

and here is the new 1st stage compressor LG NJ362
http://www.benchtec.co.uk/1/cascade5/water/IMGP0049.jpg
hey baz wouldn't you be worried about the water condensing some of the refrigerant before it hits the codenser? I guess that wouldn't be a problem as long as the desup is aboce the condenser so any liquid would fall down towards the condenser hey. Nice updates!
Looking better every day! :up:
hi tom thanks for the input
in this case the DSH is for the 1st stage as i have increased the compressor size quite a bit and i was unsure if the condencer i am using will be enough
also i am experimenting with water cooling in phase units of late and interested to see how it fairs
I just got my :banana::banana::banana: packet out and OMG thats huge! I like it alot Baz!!
Oh and when i saw the rear end of that WC unit i was hang on a WC'd PSU, not Baz! LAMAO
Can't wait to see this dude. Sorta a benching/test/sample/idea creation cascade. How manny elements can be entered all in one case.
Yes i am thinking dark and deep today heheh
just finished up fitting the new compressor and water cooled coiled DSH
its made from 5/16 copper in 1/2 copper pulled around a cylinder of R23
still have to make up a mount for the DSH
http://www.benchtec.co.uk/1/cascade5...H/DSC00724.jpg
http://www.benchtec.co.uk/1/cascade5...H/DSC00726.jpg
as you can see from the pic the new compressor is very large:)
Very nice buddy :yepp: - coaxial condenser for first stage desuperheater. :up: I hope the water cooler works well or you can boil hotdogs with that compressor :ROTF:
Your builds compare to Cold_Ice in perfection.:D

Very very very beautiful work bazx, nice paint job, as well as great plumbing. The higher content silver braze looks great everywhere as well.
5/16 in 1/2? Yeah that is perfect, 3/8" is too tight and 1/4" is a bit loose but works. I do like 3/16" in 3/8" as well.
Very nice indeed, looks like a store bought one!
Beauty of zip ties and paint ;)
surprising what a drop of paint can do
i will be painting all the exposed copper on this unit once complete
as its shine soon fades
here is the parts used for brazing
http://www.benchtec.co.uk/1/cascade5/brazing/
after brazing i clean up the joint with fine grit paper and use some wire wool
Very nice, shame on the cover up
I've been debating about painting the copper on my units also, I really hate the look of the tarnished copper after a few months :( Maybe a clear lacquer? Need to research melting temps and such.
Your attention to detail is something that is increasingly missing in most any type of work in today's world. It defines the word craftsmanship. Thanks for sharing.
thanks for the kind words but for me i am just having fun and its not hard to take my time when its a hobbyQuote:

sorry about all the temp probs all over the images i was having a look at superheat as well
the white prob line is T1 going in the DSH and the yellow is T2 comming out

Braz, you should use flux only when strictly needed as it is considered a contaminant in the system, a rather nasty one too! Or at least use it very sparingly.
Impressive with the desuperheater! I didnt think it drop temps that much.
EDIT: Now that I think about it... could the water just be cooling the copper and not the gas so much? Im sure the pipe running from the compressor to the desuperheater is quite warm, and the water is just making that cooler. Not sure though.
True, he should move the discharge probe closer to the Hx to get a better compensated reading, to know how much it is truely cooling he'd need the probes in the gas stream.
decided to test an slhx for the water cooling loop
its 5/8 with 3/8 running thro the middle
just been water testing it for leaks
will hook it up saturday and see how it works
http://www.benchtec.co.uk/1/cascade5...b/DSC00743.jpg

Looks good, love your craftsmanship.
you have som interesting ideas bazx :)
we don't see much watercooling in phase change here.. glad to see someone introduce it :)
If I understand you want to use some of liquid refrigerant to cool the water loop that itself subcools the HP line?
That's even worth than an SLHX (useless, once again) :D
No, I think the liquid is still cooling the refrigerant.
How would the liquid cool the return gas in the suction line? The gas is colder than the liquid.
I think hes using the SLHX to cool the water even further for the desuperheater coil.
That's exactly what I've said, and once again a classic SLHX is useless, a water loop even more (if that's what we think)
slhx isn't useless.. everything depends on what kind of unit and load you're aiming for.
it's pretty common on bigger r404/r507 units. But i would be carefull using a slhx as it raises the superheat. A high compression ratio and a big superheat can 'cause some issues with the oil and in worth case a broken compressor.. But i expect everyone who is playing with slhx have an eye on temptures, superheat etc..
slhx can gain or reduce the capacity of a unit depending on what unit and how it's used.. it's important to remember that the enthalpy isn't same for gas as liquid..
normally if you have a big compressor you can gain a little by putting a slhx.. which we also have seen on some SS builds with oversized rotaries. Everything depends on what it's used on and how it's used. this isn't a easy game.
regards
Tim
SGHX Is essentualy an unloaderof sorts. For this aplication I think it is a poor choice as you need the capacity at the head not unloaded to sub cooling as the liquid line runs are not so long as to need it.
nice work bazx, ya taking overclocking to the next level here hey ;)
Lookin good, love the high silver and flux still, and proper reducer usage and stuff (though I prefer to swag everything myself).
Kinda tough to swag .625 to .375 :D
There are tools to crimp down I beleive as well :)
Also, you can swag 1/2 to 5/8 and 1/2 will fit over 3/8" perfectly like a sleeve ;)
On cascade it is, yon loose some capacity for nothing... Once again remember the cascade that used one and couldn't get any lower than -33° on HX, without it it went down to -45...Quote:

Love the work done
after trying the slhx i removed it
it failed to give me the results i was looking for so
i moved on to the large water barrel:D
and a pond pump
more images here
http://www.benchtec.co.uk/1/cascade5.../watercooling/
http://www.benchtec.co.uk/1/cascade5...g/DSC00781.jpg
the pump is the same unit people use in there garden
the idea here is to take the cooler water from the bottom of the tank
and return the warmer water from the dsh to the top of the tank
and as the water cools it drops to the bottom
http://www.benchtec.co.uk/1/cascade5...g/DSC00783.jpg
http://www.benchtec.co.uk/1/cascade5...g/DSC00780.jpg
this has worked so well i am going to stick with this for a while
in this image you can see the loaded temps/pressure of the first stage
13bar / -50
this is by far the strongest first stage i have ever built and to say i am happy with it
would be an understatement
(the load is coming from a X6800@4900mhz/1.8vcore 32m run (more of this later))
http://www.benchtec.co.uk/1/cascade5...g/DSC00795.jpg
Glad you found what you were looking for:up:Quote:

i was unhappy with the vapo type dsh on the second stage so hooked two fans up
to a larger unit
http://www.benchtec.co.uk/1/cascade5...2/DSC00770.jpg
before i went ahead and made up the gpu line set i wanted to load test
the evap
evap used in this load test is one of little devils chilly clones
o/s is just my desktop vista
the cpu is a X6800 @ 4900mhz
m/b asus commando
vcore is 1.8v vmod and droop tested with meter
load is super Pi 32m
T1 is temp taken with the temp prob taped to the outside of the evap
T2 is temp taken with the temp prob taped to the suction return about 10 mm away from the evap

really nice temps bazx..
dam this build is a work of art, it soo nice, as are all of your projects
How come you're not running two instances of super pi to fully load the chip.?
32mo doesn't load the chip like TAT or Prime do anyway.
What where the results with SLHX to make people be aware about their unefficiency on cascaded systems? (:P). Your first stage is powerfull with this subcooler (I think it's more a condenser according to the size of the "air-condenser" and the discharge pressure, but anyway).
You should try LBP compressor (CAJ2464Z, for example) to make this wonder unit work as good as it looks nice :)
thanks krullet

in this case 32m is just a tool for me to compare this unit to others i have built
and have found that just running a 32m @ 1.8v will give more then enough load
and most importantly for me a variable load
Also as i build these units for benching
I know that if the unit can pass a 32m
At the set mhz/voltage it will also be able to get thro a 3D06 cpu test
you should try it with your 2 stage
@Clemmaster there was no improvement with slhx it was just the same as without
so no gain and i removed it
with what i have learned so far i now want to completely water cool the first stage
Pushing the boundaries of accepted phase knowledge in his ceaseless quest for freezing perfection,my mate Bazx.Rock on matey.
You are to be admired bazx :up: Let's get this back to the top where it belongs
No doubt Ron!
After reading thru some old threads as well as some other hvac information, I see some watercooled HX's mentioned, but I'm suprised we never really adapted to this, maybe because it is a little bit of a hassle, but the gains seem quite great! Especially on autocascades where you really want all possible refrigerant that can be condensed, condensed, and saturating as much higher pressure refrigerants as possible!
Only thing is copper prices are higher and such, so I'm thinking about trying this with some plate heat exchangers.
thanks lads
i need to put up some more images of the unit as it is now finished and installed on my benching table
i have gained a great deal from this build and i have a feeling it will become a 3 stage next year
the shut off hand valves have work like a charm as well
i just close the liquid line with the unit running wait 1 min and close the suction return
turn off the unit and remove the line set with no charge lost
I love bazx work, it's mind blowing and i can sit and look till the cows come home. It's shear artwork
Bazx winter time that watercooled HX could be fun when we get some sub ambiants and snow!

Started running some load tests with cascade 5 and a 8800GTX kindly lent by
Raja
Thanks man i owe ya one:D
In the tests i was only looking at load on the unit not bench results
The card was over clocked to 902 core @ 1.55v using riva
The cpu just ticking over @ 4.8
Load is future mark 3D03 which it completed fine
The cascade evap temp (measured 10mm from the evap on the suction return) did not move more then 1 deg during load and sat around -104/103
o/s vista but for the next set I will put xp on

Bazx you one lucky guy. Can i be your son or have you babys!
Lovely setup, clock in backgorund is nice!
I love that bench/works area. Very nice.
Awesome temps :up:
Nice going mate,lets hope you have the other one ready for these 2 ultra's by xmas,lol.
i will need to make up the sli line set just need the right evaps nowQuote:

True quality mate,. best and cleanest home overclocking setup in the world. Well best i seen anyway. :D
wow some really nicw work there man
:) Truly outstanding mate, you have set the bench for all to dream about with this setup, as 4Qman said this must be the best looking setup in the world and i should know i have seen it.:)
:D Well done again mate on a great job, now lets see it in action with some of your benches. :D
