    i would also contact tom holck, hes in denmark, and either made or had made for him a beauty of a cascade, so he would have some reseources, and i imagine denmark to italy shipping isnt that much $$

    can you see the light? is it shining too bright? can you see the light at the end of the tunnel, i know i do, i know its true.

    omg i really hate that 100 posts thing for classifieds. ive been browsing these forums for years and never posted, im a frequenter of ocforums.com. i do see the reason to have over 100 posts to purchase anything though, theres some crazy ppl out there.

    also- just my opinion but i think you should lock the classifieds UNTIL YOU GET the 100 posts. i know this would lock me out of them but i guess i can wait

    I hope to have such a beast shortly, 24/7.....the oil sep im making should be darn efficient, multiple layers of a very very fine woven copper mesh - and ive got some idea's for a automated 'maintanence cycle' to get the system to perform to get rid of any oil in the evap.

    Btw, insulation and condensation is no longer a problem, since i obtained 10 metres of this low voltage flexible heating wire - can put it anywhere, cut right down on insulation needs - and since its only a few watts of heat here and there it wont effect temps at all (compared to cpu heat loads of 150 watts etc, a few watts of heat, of which less will actually get thru the insulation, is hardly going to effect anything)

    If its low enough not to produce enough heat to matter, its low enough not to do anything about the condensation.

    Missed the point entirely there - the point is that sometimes your insulation in places is just not good enuf to keep surrounding parts and the insulation itself, close to ambient temperature (to stop condensation). It wouldnt take much heat, from heating wire, etc to stop this - we're talking in the couple of watts range here if your insulation isnt too bad.

    It's very difficult for example to stop a graphics card gpu thats at -80 celcius, from forming condensation in the AGP slot - because the cold will travel to the agp slot (i know technically the ambient heat on the agp slot and its connectors will get absorbed by thermal conduction paths back to the evaporator, but for simiplicities sake i will talk in terms of 'cold travelling')

    By using thermal wire near the agp connector on the card, this cold can be stopped from travelling further down the motherboard where it will cause condensation - it would only take a few watts of heat as less than a few watts of cooling power reaches the AGP slot via thermal conduction paths.

    It's not like im trying to use heating wire alone! lol, i'm just using it to make low wattage heat barriers that will raise temps just enuf to stop condensation - again it will only take a few watts in these areas - the insulation will be doing the rest of the job.

    It's much easier to put a heating wire round the agp connector on the card than it is to insulate a large section of the motherboard Low wattage heat barriers work very well in tandom with insulation - you can get aqay with half the insulation necessary or more - and only end up inducing a few watts of heat into whatever your coolin.

    Insulation can keep 95% of the cold in....but to get that last 5%, you require twice the effort and twice as much insulation...where heating wires can easily take care of the last 5%

    Yeah, I completely misunderstood, your method is great. I thought you were going to try to use the wires alone.

    that's awsome fruedog...do u just run a current through the wire?...how does it work?

    The wire has a resistance of 75 ohms per metre - so using ohms law, you can get X wattage per X voltage per length.....so say i had just a 20cm length, thats 15 ohms, if i ran it off the 5v line, that would give me 1.6 watts of heat - which is fairly hot for such a thin cable - plenty warm enuf to do the job of heating....if i needed more heat, i could run that same length off 12v - thats almost 10 watts - bit on the hot side that would be!

    I intend to use the stuff on my controller board, which has a 0 to 100% variable PWM output - i can then basically make it run as hot as i want.

    This sort of cable normally cost's a fortune - but i managed to pick up this 10 metre real for just £12! from http://www.wires.co.uk/

    Thats the place i also got hold of the super fine copper woven mesh for the oil sep - they do lots of scientific materials and wires, stuff you probably couldnt buy anywhere else in small quantities.

    ya doesnt some sort of retail prometia ship with elements? or somthing? its an awesome idea..its got a nice color...just snake that stuff around the block even to hold back even more.

    how thick is the wire in diameter ?

    It is about 2mm (i sent a PM)

    But it does matter. A wire that is 10mm thick isnt't very easy to use

    I got 1 question,with my vapocill LS @4550 under load the temp on the evapor is around -38°,on the CPU around -12°
    wath wuld be the temp on a duall cascade under load?
    tnx

    under load i'd say around -100c on the cascade evap, meaning -80 or so on the cpu.

    made me badly worry why macci used dryice to brake the 6K when he own it self a duall cascade.... any exsplanation?
    tnx

    Afaik one of his compressors from his cascade is broken, he wrote that somewhere at xs.org
