    You drill two holes in the side and one in the bottom. The bottom hole is used for the separated oil, the lower hole in the side is used as the inlet, and the higher hole is used for the gaseous outlet. I personally would use the hole for the valve on the top as the gaseous outlet and drill out the valve so you don't have that leaking under pressure and low temperatures.

    Sorry Luke, but this thread is going to Customer/Builder relations so we can control who post in it.

    Please notice guys, that those are phase separators :-)

    So bottom hole is used for the oil AND gas in liquid state, top hole is for high pressure has, which isn`t liquid yet, so we can get them separated in simple way. Not 100% of course.

    symphy, for what temperature we should aim at this time ? I`m not overclocker and don`t know todays cpu`s, what do you wanna from that unit.

    edit:

    Cascade got second condenser

    Sorry I couldn't include some batteries, but that's the easiest part to get anywhere I suppose ( and I only run rechargable's myself which are rather expensive and not to say useless without a charger ).

    Gotta photos :-) (sorry for mess in celar)

    Big thanks to Marvin, you know I luv ya my friend



    Concept with two condensers (one for 1st stage, second for 3rd stage).







    Some frost.



    +0,5bar (7psi) suction pressure @ -76C (manometer is domaged and shows always +1 :p)



    two way cut-off switches



    manometers



    Fan for extra condenser




    New 3,7kg bottle of ethylene



    and some sub-zero temps @ 1st stage.

    That`s all for now.

    Looking good Luke, keep on working!

    P.S.: Is that condensor on third stage being used as R14/R50 desuperheater?

    I'm guessing you blew out the gauge then running a high static. I had that happen once on a gauge, was pressure testing to 350PSI and the low-side gauge was permanently damaged.

    Looks great man. So lemme see if i have this straight, the first stage is an triple autoc? Where would the second condensor that you're using as a desuperheater go? Right in next to the other condensor? Sorry, I'm fairly new to phase (but will have firsthand experience starting tomorrow)

    Good luck,
    Eli

    Hello

    Yeap, first stage is triple-autocascade (let`s say, pseudo, because now it`s autocascading a bit, should be there -90 at least)

    The second condenser will be just after oil separator on third stage (wanna have around 20*C on condenser exit, less load for other stages).

    @ [XC] gomeler

    Yeap, I got too big static for that gauge

    Gotta arranged final parts place, I resigned two-condensers idea.

    Choosed two powerfull compressors for II and III stages. Assembled everything. Gotta buy captube, few meters of 6mm pipe, insulation and oxygen for torch and it will be done.

    gotta question about dual captube feed. How I can use it ? It`s idea for big load ?

    Dual captube works fine if you don't have a wide enough bore single capillary tube. I used two 2.6 meter 0.7mm bore capillary tubes b/c I didn't have any larger capillary tubing. This was with a 7/8hp compressor and a slightly undersized condenser. Held the 2nd stage just fine(3/4hp compressor) but I would have sized it to around 2.8 to 2.9 meters to reduce capacity slightly in my build as the HX could have been colder. Just play with it, start with a longer length than you think you'll need and trim it down as you go.

    So If I gotta 0,8mm captube, I can easly use it ?

    I tought that dual captube is "new trick" in phase

    It's less of a trick and more like a work-around for limited resources. Cheaper to stock one size capillary tubing than three or four which helps when you are a poor university student There's a way to calculate the capacity with multiple capillary tubings, don't know where I saw the charts though.

    Nope, it is definitely not!
    It makes it just more complicate. So if you're able to get bigger captubes, better use that.
