Where can I find a bristol comp like that?
so can anyone send you their prommy for an upgrade bowman ;)
You better watch out bowman, or you'll have a whole new business soon. :D
Wow, excellent work Bowman !
That a nice balance of temps you've managedwill be interesting to see how it runs on a system, then when its cascaded that should be a sight to behold :slobber: :slobber: :slobber:
Great work, Bowman. And the best is yet to come. We both know that ugly white "F" stuff is keeping it from showing what it can REALLY do. :D
Being that you push these systems right to their absolute limits, I wonder if that 1 HP compressor has been given a hernia... LOL
Personally, I like the desk lamp mod. ;)Quote:

took me most of the day to get it finished.no benching yet but it is running .i need to do a fresh install of win2000 and them bench,
here is what it is looking like so far.
Nice job
VERY NICE! To bad its a total mess :p
i woulndt say thats a mess....ive seen allot worse..IMO thats about the best its going to get unless hes a neat freak which it doesnt look like hes affected with a lil mess here and there;) nice work bowman!Quote:

Bowman, how did you finnaly insulate these evaps ?
Well i left the ceramic coating on and made boxes and sprayed foam just like i had been doing.then covered the foam with armorflex.used pipe insulation and colored sleeving to finish it off.just have to do the rest.Quote:

by the berkut.....i like the avatar:D
But as it seems the ceramic coating is almost useless :\ Its only good to full the space between the evap and isolation :\
What temps do you get on this system ?
Ill start making my system in a few days when my flex hoses arrive ^^
why didnt you rotate your mobo by 180*, your gpu evap would be base downwards, you would have better temps ^^ Since you made a new "case" for everything it didnt matter (?) how would you position it.
thx, i think it suits me more ^^ Thats Rayne from Bloodrayne ^^ Great game, played today for over 8h and now i have a "computer hangover"
I think his main plan is to throw his Intel rig on this bench, after testing the triple evap out first. Go baby go!
I'm thinking my 3 GHz+ 1700+ chip could be used there :D :)
I do know JC he's ready to give that a long hard ride!
Hey Bowman, What is that colored wrapping youve been using and where did you pick that up? Thanks
well guys would post a pic but i have to reload window tommorow to see how far she will go but......
I did manage to make a couple of 3d2001se passes over 3.0g on a amd.3013mhz @2.1v to be excate.which was running -38c,the r9700 was benching at 500core.turning in a couple of strong 20995 scores.this was with a old 3.1cat set.i cannt get 3.2 to load with my patch like i used too for some reason.so i will try a fresh install of windows tommorow.shouldeasily turn a 22500 ot 23000 score for a r9700 that will be stella.....then i will mod the r9800 maybe this week.
what fsb are you using ?
well with only a short bit of time to test,it was running 231fsbQuote:

i have to fine tune the bios and do a fresh install of windows tonight.
been a while since i can been benching,not sure what the fastest cat drivers are right now for win2000 and amd...anyone know for sure.if i am going to reload i may as well get the fastest set installed first.
i did a quick ORB search this morning and found the #1 amd r9700 spot is held with cat3.6.win2000.so that is what i am planning on tring first.
but i was impressed with the load.it was holding a good -36c to -39c temp range.by the volts and speed that is putting 190watts of heat.but hard for me to believe that.it may...just used benchtest.com to caculate it out.
I would test how high the system can go before reinstalling windows ;]
These temps are evap temps ?
Well i always ghost anyways.
thats the first thing a bencher does.get a clean setup at default speeds and then ghost.saved me countless times.it is just i dont have a clean image for the nf7 abit board.
as far as temps goes you cannt go by the motherboard thermistor.i thought every living sole knew that.the thermistors abit and epox are not worth a penny at cold temps.
i was in my bios last night and it shows a cpu temp of -74f which is impossable,i trust no socket temp thermisitor.
i have such good contact the board had ice once midway between the chipset and cpu towards the ram.i placed some foam to cover and seal it.but i had to keep a strong fan blowing on it to keep the moisture evaperated until i can get in there to protect the upper half the board better.
anyways we will see later it it even starts back up.you never know with these extreeme machines
Use the heater from you vapo ;] Think it will work nicelly on the mobo's chipset
The termistor on the 8rda3+ show really nice temps, but ill buy a MAX controller
Damn i have to start using ghost... Anyway i got 19.2k on my fx (here) on my half dead system (sobix + blaster and other god damn things + corruptions caused by testing) and no o/c on the vgaQuote:

you connect it to the smbus and directly to athlons thermal diode
ok I got ya now, thanks berkut
MickeyMouse - believe he's testing out JC's old 1700+ at the moment.

If you need an unmodded NF7 V2.0 that'll give you

d10 BIOS will get ya there.
well got a fresh install loaded and then i started getting errors...guess what?condensationdripping into the video card.i am having to take the board out and reinsulate the upper half the board.with all 3 evaps the board itself gets cold to the touch almost to the ram slots.....
so it coming down now.i hate tearing it back down.
o well thats what i get for making the thing cold.more worklike always....
I know it's more work....but it's not really work, it's the R&D that everyone is waiting for...it's the Leading edge of phase change technology...it's just more Bowman!!! The best is coming soon!! :)
yah its hard to believe ur the first to do this.....
Im more and more liking dabits vacuum box setup for condensation reasons and rma reasons, itll be all good once setup.
]JR[
well got the upper half insulated last night.and had time for one bench....ran a 21798 the first and only bench i ran.got too late.but for some reason now after the new windows install it wont run at 3013mhz,not sure what that is but i will work on it later.
condensation is a problem when you cool the chipset down.the cold just travels the board. right to the agp slot.i have been lucky so far that i catch it before it took out my card.
JR yep i like the vacuum box more and more,
How are you insulationg your board? I have 2 that I would like to have done for the prommie (Bowman Modded) and Crossbow.
I want to be able to RMA them if needed....what do you suggest?
Thanks :D
i will post a good pic tonight,sorry just been busy trying to get the new triple going and kidds started school this week so has been a interesting week.Quote:

one more little thing...i did get a score tonight for the orb...not bad on a 9700 pro..but i will have to tweek it alot more.
Superb job there Master Bowman..
baker18
goddamn lol whered the mobo go? all i see is neopreme;)
Clear!!!...Cleared for take off!...Ready to fly!..............:)
i love the way u made those plexi glass tops to hold the blocks on;) and also the green one on the 9700;) what are u gettin for an oc on the core? ne higher then 479?
well i was a volt modder way before i started refrigerant cooled pc's. so the r9700 is running......as far as i know this is one of the fastest core speeds....506core. memory never was much 353.
yea thanks MickeyMouse that was the 4th ot 5th bench it ran.but i am starting to have the cannot publish problem again...i remember now how much of a headache it was....it is proberly the timming.
i am running only 2950mhz seams i cannt run any higher because i am pulling to many amps though the board.i can lower any voltage and then increase another.but i am tring to push the memory as high as possable.right now it is running 2 2 2 11 @227 x 13.i may have to back off some of the timming some to clear a publishable score.
not sure how much i will get done this weekend,but i have a mach II to mod and finish,and another custom one for a man.
i will keep you guys posted.
Good to see you benching again! :D

i did a little looking today on the orb.and if i can get the bugs worked out and get this one published.it will be the # 1 AMD r9700 score....i was suprised to see it did that well.unless i am looking at it wrong.
http://www.xtremesystems.org/forums/...&postid=214980
nice scores ^^
think my fx 5800 could catch up with you (but seriously i dont knnow), at least it does in the ntaure test (153fps @ 570/1140)
well i did it.put the amd xp1700 at the #1 spot for a AMD and R9700....got it to publish at 22312.....got to try and go now for 3dmark03
edit...forgot to say...r9700 is running @ 510core....woohoo...i believe that is one of the fastest r9700 core speeds ever
also i make 3 more capillary tube adjustsment to the triple evap,bench rig.
went to adding tubing until i saw the temp start going up(showing the evaperator was starving for refrigerant)then i shorted up slightly...it is very time consuming,but i know now the minimum cap tube that can be used on a r9700 @1.93v which is alot of heat.and what the cap tube is for a xp1700 @ 2.1v...
got the rig running CPU @ full load -40c and the GPU @ -42c running 3d2001 full steam.

Wow....benching that 1700 at 2964! :eek:
yea running smooth.but the board is holding me back.i have pushed it to the edge.....HA HA HA..if i add .1v to the cpu it locks,add .1 to the ram it locks.....i have maxed the amps that can be pulled through.i can run past 3g at lower fsb and higher mulitpler but not with the scores i have.the twinmoss is killer....228 running 2 2 2 11 now thats tight.i have adata pc4000 and hyperx pc4000 that wont run close to this ram.Quote:

the cpu is not doing bad.running -40c and the gpu is -42c until the room heats up to close to 90f (33c ) then they drop to -37c and -39c....but still thats pretty good with the heat.
Fantastic job Bowman!!!!!

Hey Bowman, Where can I get a bristol compressor like the one that you have running the three evaps?
Not to disillusion anyone, but of all the compressor brands out there, Bristol has the worst reputation.
Whatsmore, I don't know of anyone who makes a compressor specifically for very low temps or cascades. These systems use regular everyday low temp compressors.
Whats a good low temp compressor?
Nice going bowman :)
dont know whats up with the futuremark ORB not finding all R9700 scores but atleast my project manager has one 9700 @7.2k ;)
yea i know i ran it now is shows,,run again and it disappears...LOLQuote:

you wont,they have been discontinued.Quote:

and finding a good low temp compressor will be expensive,but i dont know what to tell you .it is hit or miss.
i have spent lots of time and money just swapping out compressors until i found one to work it.it is hit or miss.
just like cascades.the proper low side refirgerant is normally something like r508b (95 )or r23,something along them lines.and the cost of that stuff goes way over $1000.us for a can of freon.
so these toys i have cost me lots.which at the moment i am not spending that to just play;)
anyways i havent been working this week in my shop much since i have beed swamped at work and at home.
i do have a mach II i am tring to finish up today.
and i did spend yesterday morning tearing down my cascade and make a new frame to hold the new version i am working on.
as it is a normal cascade,but i am making a few modifications which is not normal,but as always i dream up new things to try.i have been always lucky as i can design in my head and picture the outcome.then i just build them.
but it will be differant.:D
I like the Copelands, with Tecumsehs second. Danfoss is getting a very good reputation, also. There are many other brands out there that I am just not familiar with, so have no opinion.Quote:
Whats a good low temp compressor?
As a rule, all compressors are pretty rugged, but some more so than others. None are noob-proof. Common causes of failure are overcharging and charging with liquid. Systems should be vapor charged. The exception is zeotropic blend refrigerants (all of the 400 series refrigerants), which must be liquid charged. This should be done gradually, a small squirt at a time. Compressors are designed to pump vapor, not liquid.
Hi Gary, Hi Bowman :) This is a great thread.Quote:

I have become particularly attached to the Tecumseh "TPA" model of compressors in the 850,950, and 1050 btuh range, rated at -10F R-134A. I use R-404A for a -50F to -60F evaporating temperature application.
I suggest using any compressor rated R-134A for -10F or -20F (low temperature), and using R-404A for the temps we are trying to acheive here, -50F. This is a common practice in the commercial Ice Cream Cabinet industry. ;) My experience is, select the capacity at the R-134A rating at twice the design load @ -50F.
Also, Bowman - I was doing some figuring, and came to the conclusion that in the three evaporator application, that a Sporlan NIS(E)-1/8-ZP expansion valve would be a perfect selection for a three evap system, assuming a 150w load for each evaporator. :toast:

Welcome to Xtreme herefishy! :D

You sound like you know your stuff...stick around and help the rest of us out. :D
welcome aboard herefishy:toast:
glad to see you make it over to this neck of the woods.:D
well i have tried a couple tev valves,and on these systems they dont work.the temps change too quicky for a tev to adjust to the load or no load,so you get a starve condition at times,and that starts a chain reaction that is hard to control.too much refriegerant is boiling off before it enters the block so you dont get it where it is needed.man it would be nice if i could get one to work.would take alot of work off of me:D
Hey herefishy. How's it going? :D
What would you think of doing multiple evaps in series with a TXV?
Why would you prefer a R134A compressor over a R404A compressor? The valve ports may be tighter, but the valve reeds would be weaker, and the internal relief setting lower.

.... for the same reason that the ice cream merchandiser manufacturers prefer to do it that way. LOL! ... and I do it, and it works great.Quote:

Actually, you will not find R-404A compressors rated for -50F. -50F - 60F is what we are trying to acheive. most '404 compressors and systems are rated mostly down to -30F, some down to -40F. These ratings get even rarer in the fractional horsepower department. As a mtter of fact, I cannot recall a 1/4hp compressor that I have seen specifically rated for -40F.
The low temp compressors that are rated for the (lower pressure) refrigerants seem to be very well adaptable to very low temperature applications with the (higher pressure) refrigerants.
:)
It must due to the valve porting. The downside would be the increased pressure on the high side.
I'm thinking Bowman should be about ready for a triple evap in series with a TXV. The combined load brings it in range for the smallest orifices. :D
I'm wondering which evap would be the most efficient. There would be flashing in the first, and superheat in the third. Would the most efficient be the center evap or the first evap?

Bowman.... it's all yours.... mind you, you may have tried, "a couple of expansion valves", but there is only one with the proper capacity. :stick:

That's called "hunting". It's caused by the orifice being too large for the heat load. With the heavier combined heat load of three evaps, this should hopefully pull it in range of the smallest orifice.Quote:

work is killing me latley.
not saying i havent thought about the valves...LOL i have,
and i do appreciate anything you can offer to help.
as i need all the help i can get sometimes.....:slobber:
dont know the name of a good shrink do ya?:D
to run a tev valve i would need to redesign the evap's for the larger tube intake,not like i dont have a case of adjustable valves setting in my room.with every offrice they make.so wouldnt cost me anything.i just need more time to test and experiment.
but i did start on the cascade again.so that is the next thing i am fixing.built the frame,electrical box with relays and lots of goodies.got it on wheels.trying to decied what refrigerant i am going to use in the high side.as i have 22,502,404 to pick from here.since the compressor i am using has mineral oil.i could use 22 or 502 or a mix of both,or could change the oil out and use 404.
Gary what you think on the high side refrigerant?
the low side....thats in the air right now.i have a can of co2 to test with,but i am worried about the triple point.i could easily try some 410 but not as cold, about $240 a can.or go ahead and order a can of 508b which would cost me $1100.
on the prommie front...... hobocrow i have yours running at -46c loaded cold and -44c loaded hot.so it is running about the same as the last mach II:D
bowman, woudlnt R410 have a too small pressure ? like 2bar max... :O
the problem would be finding a apropireate cap tube
but you could overcome this problem using a fuel pump on the exchangers outlet that would increase the pressure to like 10 bar.. :D

Didn't I see a post whereas you received a bottle of R-170 (ethane)? If your going to use R-170, you would want a 1st stage evaporating temperature of -10F to maintain a second stage head pressure of 173psi.... or +10F to maintain a second stage head pressure of 239psi. It would be a low or medium/low application, nonetheless.
What would be the ideal range for a R-170 pressure ratio, I wonder?:confused:
Hey! Where's CaptainCascade? :p:
What do you have a case of? Sporlan "Q" valves and orifices? The smallest "0" valve won't do it, it's rated at about .22 tons @ minus40F SST R-404A. You need a valve rated at about .11 tons. The best selection is the Sporlan 1/8 valve, of which I like the NISE-1/8-ZP. Externally equalized for sure!Quote:

;)
Well ..berkut ...410 will work if you can put it in a deep enough vacuum but temps would only hit ...i am guessing around -65c on a slight load.it is just the cost is alot cheaper.
herefishy na....would be nice if i had a can of r-170 ,but i dont.
and you are so right about keeping the low side at a high enough condensing pressure to work right.but i will be able to adjust the high side with refrigerant to fine tune the evaperating temperture of the high side.this will allow me to change the condesing pressure of the low side....i hope:D
it's all about fine tuning.......damm i sound like Gary...i am feeling old LOL;)
Could try NOS, although similar triple point problems to C02 apparently although lower temps, looking at the phase diagram in the overclocking section for C02 looks like its a non starter anyway...
I found some ethylene at work, ive stashed it and going to see if any1 reports it missing ;)
