maybe this picture of her well show my reasoning to stay out with her on weekends..i dont want you guys to think i am lazy...LOL
Nice girl too....;)
BTW, what is the best way to fit a Prommie to a Radeon? Any advice would be appreciated. Preferable some all around solution. It would be nice if it could be used on future cards as well.
Found the info good read for all when pumping down from jb website in technical info then deep vacuum principals...http://www.jbind.com/
The purpose of evacuation is air removal, not moisture removal. That's what driers are for. Yes, a deep vacuum can remove small amounts of moisture, but that is not why you evacuate a system.
What is a deep vacuum? When you get down to about 29" hg, you are in the neighborhood of 25,000 microns. To remove moisture, you need to get down to about 500 microns or less. Unless you have a professional quality vacuum pump, you are not going to remove any moisture.
Removing air is the goal, and a triple evacuation beats the hell out of a single evacuation for this purpose, no matter how long you single evacuate.
well ....i finished triple evap my cascade...after i was satisfied i charged it with 410 to check for flow...so far it works pretty well..
the improved evap i designed for this application is doing very well..the unit drops down to -105f...(-76c) while on its pull down cycle...and after a hour being shut off the evap was still -50f..which doesnt tell much other than i have lots or area inside to hold refrigerant.
but enough on that...
i have 3 projects going on other than ithis....
one is a friends of mine...he broke his prom lower hose at the flex connection..this one is getting a baker new style block and new evap cover....this one is setting now letting the foam cure in the evap cover...i remade the entire copper hose assm and made a slighht mod to chip cons design...
i hope to have it on a vacuum today so i post a pic..befor i head out tonight to the night club.
second is the 410 prom i am using a 226 tec on to bring the condesing pressure withing reason...i am still installing a hi pressure shut off for safety...tring now i figure out how to get all this inside of a stock prom case and still keep my airflow....
and working out in my head a improved return to the compressor so i shouldnt have oil return problem(tring to think ahead)
and last...
well this one will wake every one up to the my latest brain storm...."MACH II TO THE MAX"
a complete stripped down mach II...complety moded..replaced compressor,increased condensor size and fan shroud assm.
one question i am going to ask of the forum....this mach II to the max project i am going to do...what would everyone rather see?
a dual evap MACH II....running in the -50c range
or a single ultra low temp unit....capable of hitting -65c to -70c temps.
and just for info guys..i am not selling or doing this mod to anyone ....
i am not into this for money like some.....i am not money motivated...i am honor and pride and respect motivated..i started doing this before anyone else even wanted to fool with these projects....i love the challange...not the money....i will die poor maybe...but i hope happy..sometimes i wonder..but i still get up everyday and move ahead...
Thanks bro - I sure appreciate what you do.
I'd like to see a dual, one for the cpu and one for the video card.:D
well let me show ...
this is the baker block and evap assm curing waiting to be connected to the prom:D
and this is the mach II project..so far....see i have been playing and thinking...:D
i start with a gutted mach II case
this is the 2 compressors side by side..going from one to anther
this is showing the condensor size upgrade...
and this is how it fitts......i have maxed the case as far as compressor and condensor..this will be a pretty compact unit//no room for errors in piping and instaltion..must be planned out well.:D
Where is the sensor machined into the block at?Quote:

well cannt see it and i didnt take a pic...:(Quote:

what i had to do..is the rtd temp probe i had to fitt the controller is 1/4" in diameter..so to give it more surface area.i cut a groove into the side of the baker block so i get better themal contact...the black cable comming out the housing..is the rtd sensor
Thanks for the explanation!
If you don't do the dual, then you probably don't need the oversized condenser. What refrigerant will you be using?
I bet I know where you got that larger compressor. ;)
Looks nice...tight fit but then you're good at working in those tight places...I know...I own a good example. :D chiller tank in "Crossbow"
well proberly going to try the 410..Quote:

now i have r12,r22,r502. 134a,404a,410....
410 may work if i can keep the head pressure down to a reasonable level.i am thinking i can if i tune the unit to near perfect conditions..but as with anything i may be using 410 in..i will try and use a hi pressure switch to make sure it dosent hit too high pressures.
if i go dual evap i may stay with 404..since i doubt if it can handle as much 410 as it will take to properly cool 2 evap's.
Bowman, what condensor is that? do you have a model num?...:stick:
Is that a SC12xxx ? Will you try the pelt condenser idea ?
I finished my friends system, now its time for some leak testing... Based on a SC12C, R22, works like a charm, if you guys want ill post a pic or two..
Love the way it looks, good job, im waiting for more.
I know pelts are very compact. Is there such a thing as a less compact pelt? The more surface area contacting the heat exchanger, the better. Possibly a series of small pelts?
ya gary a good one i would use is like a laser chiller....they are a series of pelts lined up on either side of a steel plate(or copper..) and the pelts cool the plates which in turn cool the water...people have used them for water chillers for there watercooling.... to be exact my man S_I_N over at extremeoverclocking has one that he uses dual psu's to power the like 12 50watt tecs or something dont quote me on that but iknow hes runnin the pelts in a series.. ill see if he can post here to help out:toast:
well its not that a pelt itself is large,but you have to remove the heat that it creates and that takes large heatsinks..with powerful fans,or water cooling blocks..
now take a pelt and connecting to a large water block or heatsink,,and then remembering it has to be close to condensor and heavily insulated...well this starts to take up room....
now if are not carefull you will restrick the airflow enough to cause a problem with heat...
i know it sounds easy....but it isnt by a long shot...if i just stick it on on there without making it look factory equiped .it really isnt worth my time..as i try and make top of the line stuff only...
it will come around...i am looking at a idea right now of cooling the drier...this would kill 2 birds with one stone per say...
if i can subcool the drier..this will help in condensation of liquid where it matters the most and easier for me to insulate the cap tubing than 5/16 copp[er tubing..because if i cannt keep the once cooled liquid in the drier cool...it is going to gain heat and pressure.so i have to keep it cool once i get it cool....
i think the drier may be the easiest and most effecient way to do it..the driers i use are large enough to help in cooling the gas...i hope:D
