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. :banana:

Geez your still not happy with it Cryo? :eek:

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::toast: :toast: :toast: :toast: :toast: nice temps!

20/195 is prolly the pressure in PSI

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

No, ever heard something about critical temp/pressure?

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

-185,7 °C @ 1bar atm :D

?? 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.

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

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!:eek:

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 ? :rolleyes: I know “show some pictures” I will. I raided my barn and here is what I found: some things to work with.:banana:

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 :toast:

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 :wth: :D

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 ;)

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

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...

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

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

im not sure your point, i never said it wasn't loaded, and i never brought up a PT chart either.
05-13-2006, 12:37 PM
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?

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 :p:

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.:toast:

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 :)
