brettneck:
doesn't everyone like to blow stuff in the air?
maybe it's made in a phase mine who knows
anyway a basement is almost a mine.. it's underground

Take it easy pal. It was "Duh" who bought it up in the first place. I'm not flaming or intending my post to be agressive/nasty in any way...

I go by a good old German saying, good is not good enough, live long by it or die with out it, is another one guy would say about safety regs.

From an industry I grew up in, there are old logers and bold logers, but there are no old, bold logers. In other words, it never payes to not take simple action to remove the possibility of a failure.

Anyone remember stewie,I sort of mis the guy, Do I here a hint of Xeon catching on to the safey #1 Rule.

Hi

Yes kayl, but that is planned to be working with R507/R23 as I've wrote some posts over . R1150 isn't need, with ethylene, cascade rather will be too cold for owner . For sure first I'll try R507/R410a, maybe later I'll put R507/R1150 just for test (if mine new ethylene portion arrive on time ) . But that's not sure . Finally I plan R507/R23 .
I'm not able to put plastic shield on cables near condensor - it's too little space there, between pipes and condensor .

k, so what temps are you aiming for, with 24/7 application. -60 to -80c some where?
Like the way you did the oil sep return, when the float opens have you ever noticed a drop in temps, i have read of others having trouble and using capillary line return?

k, so what temps are you aiming for, with 24/7 application. -60 to -80c some where? yes, exactly -65-75*C@200W
Like the way you did the oil sep return, when the float opens have you ever noticed a drop in temps, i have read of others having trouble and using capillary line return? Sorry I don't understand what do You mean with those oil return ..can You write that in another way ?

New pics :



Suction line (braided one) is very short becasue cascade will be used in that way :





But oversized sleeve used for suction lines ...now Guys do You like wiring ?

I plan small surprise at back wall of case ...You'll see it in some next days .

Edit : Nevermind the quote was changed, it looked like that was what kayl said and the question hadn't been answered.

[Vuco]

That bolded words in the quote are Piotres's answers

IMHO, nice build Piotres, but aren't you a little pessimistic about the temps under load ?

We'll see. I rather want to be pesimistic and later have a nice surprise .

[sacha35]

Nice one mate, just a very small precaution will go a long way in your builds as they are awesome mate, cant wait to see this unit up and running.

[piotres]

Hi

Thanks for all comments .

Today one new picture, insulated suction line .

[kayl]

k ill try my best.
With the oil seperators when the float opens and allows oil to return to the compressor, have you ever noticed benching or on a load tester that the temps at the CPU drop during this time?. I have read others have had troubles sometimes that temps just drop for no reason, and only thing we could think of was when the float opened and system under great load.
For this reason they made the suction return more restrictive from the oil separator, ie used a small amount of capillary line to return the oil. For this reason i have always just used few feet of capillary line for oil return from the oil separator, but never just piped it straight back with say 1/4" copper tubbing like you do.

Great job! Get some brasso or polish on those filters .

[one_servant]

Excellent work man!

[Speederlander]

With 24/7 use and reasonable care, what is the average lifespan of a unit like this?

There is a Keeper! Marry her and lavish her quickly! Hard to find a mate who enjoys the machanical side of ones life!

[Brettbeck]

With 24/7 use and reasonable care, what is the average lifespan of a unit like this?

Probably as long as the life of the fan(s) or the compressor before anything would need doing!

[[XC] gomeler]

I'd say the fans would go first, then compressor so long as the assembly was handled with "clean room" conditions. Excellent build piotres if I haven't said it already

Love how your girlfriend has her pinky sticking up while sanding, I laughed

Hot little helper I wish my wife would help me with some of the stuff I do! Well maybe she'll help me stab the motor in in my truck!

[Pete]

Nice one Pete! I won't quote the photos but i think phase needs spicing up. So far only two of you Polish lads have photos of ya missis involved in the build! More we cry

By the way can we get away with asking specs of her unit?
