my first Cascade is born :-)

even i thought that thing wouldn't get finished....

but in the past 3 days i worked a little bit on the sweet baby :D

changes so far:

first and second stage compressor is a r407c rotary (~7200 and ~6800BTU). captube on both stages.

I just charged the first stage to look wehter everything works right. second stage is beeing evacuated.

ND pressure is very low, HD too. I charged the first stage to ND-0,3/HD+16,5.
capillary is 225cm long (TC-26).

i have got high pressure cut of, but for tests now its not connected. for bench use and unattended use ill install it.

Scary build...how you tell where stuff is

well done on the -105 bet that felt good

yes! that felt VERY good :) :banana:

edit: ethene, not ethane.

Very nice :) Love the 'smoke' on the evap, hehe.. But you got ethane in there? That's R170.

of course ethene. i mistyped...
R1150.
i'm afraid i'll have to buy a 5L ethene bottle... :(
cannbot afford that now :(

Lovely build godmod, good (amazing) job, show to as loaded temps :)

Nice cascade!

But im still unsure about the gas? Is it Ethylene (R1150), Ethane (R170), or that Ethene? Or was that a typo?

Ethene is Ethylene. and thats what im using. the A in ethane was a typo.. i ment ethene.

2nd stage gas is R1150 !

Ah cool :D!

Nice work but on serious question to ask?

What are you going to use it on?

MB, CPU...have you decided?

no. i think i'll hook it up on my E6600...
but i built this just for the fun of building :)

Well good for you, absolutely beautiful work.
If you got nothing to do with it, I'll take it. :D

Nice one. Especially liking the CAD drawing. Congrats on -105.

the unit is finished. i installed an expansion tank to decrease static presure and and a removed some piping on High side od the 2nd stage to reduce hd volume.
i have to tune it yet, but i'm out of ethylene :(

new assistant :D

Nice picture ;) and nice temps too...

regards

Ive got nice assistant too ! Welcome inda club, hehe !

out of ethylene really sucks, I know that feeling ;/
