WOW!!!! CRYO-TEK/Chilly1/Polycold Modded Autocascade Rev.3!

[Blaster]

Second test run.
Two heads cooling.
Load cell on one head.
Added 10 psi argon.
Load Inlet head out
0 w -128c -128c -128c 18/155
50 w -121c -117c -117c 20/170
100 w -117c -112c -110c 20/180
150 w -113c -107c -107c 20/195

Looks like a captube adjustment and a slight change in the blend are in order . Not bad for a first try.

Geez your still not happy with it Cryo?

hi,
Cryo man thank u for stopping by! experts in this domain always needed!
got few questions:
whats the ''20/195'' ?
U put gas by presure dont u have a ''weighter''?
cap lines lengt, plssssssssssss!!!!

regards,
q

PS: nice temps!

[Jort]

20/195 is prolly the pressure in PSI

Hay s7e9h3n, It seems that your system was unhappy with it’s identity and has started some sort of a transformation ! Must be something I feed it.

I always wondered what it looked like INSIDE

[ak_47_boy]

damn thats cold, is argon in a liquid state in the tanks you get for welding?

[cold_ice]

No, ever heard something about critical temp/pressure?

[Jort]

lol you don't want to be close to that bottle

-185,7 °C @ 1bar atm

[Unknown_road]

lol you don't want to be close to that bottle

-185,7 °C @ 1bar atm

?? what are you trying to say?


critical temperature of argon is -122*C so above that temperature it can't be liquid no matter what pressure you apply to it.

[cryo-tek]

Well s7e9h3n wants his unit back so I have to stop playing.

I’m going to return it with the no argon charge so that s7e9h3n doesn’t get over cooled. The final charge is 123, 22, 23, 14. The captubes are:
#1 = 81" x .055
#2 = 90" x .042
#3 = 90" x .042
sub = 30" x .026
evap = 72� x .031 x 2
(one captube per head)
Exp. tank= 30" x .026

I did play so that I could see what I could get out of it. Here are the temps with the thing pushed and tweaked with argon and methane. Methane worked well.

It’s the bomb!

Load, Inlet, head, out, suc/dis
0 w, -123c, -123c, -123c, 13/145
50 w, -121c, -121c, -121c, 15/175
100 w, -121c, -120c, -120c, 18/185
150 w, -119c, -117c, -116c, 20/200
200 w, 116c, -100c, - 112c, 23/225

Now I’m hooked. Next project will be a ¼ to ½ H.P. shooting for -60 to -80 @ 150 watts. Comments ? Thoughts ? I know “show some pictures� I will. I raided my barn and here is what I found: some things to work with.

[martinjon666]

do it cryo, you know you want to!

[n00b 0f l337]

Hehe I plan on doing the same sorta thing cryo-tek next weekend or so. My problem is I dont have the gases you have!

WOW....looks like the temps improved

I'm gonna let Cryo-tek have a go with a Danfoss SC12MLX I've got sitting over at Chilly1's place. (Chilly1, if you're reading this, please send my compressor to me )

Sheesh...that must be some kinda barn if you just "stumbled" upon a practically new P100. I can't imagine what it's like to have so much stuff that I'd forget about a ~$10K cooler

[fatty]

Hey cryo please answer my pm I need some handy hints

s7e9h3n will be looking forward to seeing your results mate

oh yeah an any spare chips that cant handle the cold send em over

[charlie]

a p200 sold on eBay last week for $300...

[n00b 0f l337]

Damn should have jumped on that!

i think user PC_ICE (from another forum) got -90 with his autcoscades... i dont remember what HP but i think it was 1/3...

[ak_47_boy]

ya it wont condence but will it evaporate at 3000psi if its in a liquid state already?

edit: jezuz this new sig is making me lag... rofl

[n00b 0f l337]

i think user PC_ICE (from another forum) got -90 with his autcoscades... i dont remember what HP but i think it was 1/3...

Yeah but its not bout no-load, that just can be seen from a damn PT chart. Tis all bout capacity.

[Revv23]

im not sure your point, i never said it wasn't loaded, and i never brought up a PT chart either.

[n00b 0f l337]

No no, by the PT chart I mean unloaded temps mean nothing really. If you want to see an unloaded temp just go look at a PT chart. That will tell you the BP at whatever suction PSI. Thats all unloaded tells you after all, what your BP is. Once you apply a load its a different story.

Polycold that s7 has was -160C or something at 5w of heat.
Not much use for that -160C right?

[Revv23]

i know that

now how does that apply to PC_ICE's -90 autocasecades?

like i said i did not say that was an unloaded temp. IIRC they held in the 80's

Noob correct here, in fact for club membership a standard load should be set. like 150 watts. not just reaching -100c. the whole point of XS is cpu cooling. but since memberships have been handed out by just displying a number without verifacation of any kind, The club dosn't mean much any more . thats my opinion.

But what if the unit does -100+C @ 150W on TWO heads? So then maybe a 2 x -100C club should be made

BTW, that -90C from PCIce was unloaded and it was never tested with a load. From what I've been told the unit didn't have much capacity....

BTW your using a $10,000.00 comercial polycold , Far cry from a DIY unit.


Build one from scratch to 150 watts then youll get a that a boy.

If I went to work monday and changed a asorber and recharged a helium cryopump should I get in the -250c club ,of course not,I didn't build it, just serviced it.

I can remember him personally saying it had crap capacity. Looking forward to how things goes. Been too busy to continue on experiment but I should be right back on track next week
