Cascade 6 (mobile assault unit)

[bazx]

most of the parts for this build will be comming from cascade 4 accept the comps and cases

She lived a short but glorious life 12-17-2006 to 11-04-2008 R.I.P my freind

any ho on with the new



Cascade 6 is to be a mobile unit as I have had the need to go to events of late and my current cascades have been difficult at best to move around

With this unit the compressors will be mounted around a central column along with the oil separators and most of the first stage

From this the pipe work will raise up throw a table top where it will be routed to the evaporator, heat exchangers and gauges

This unit will also have the ability to change evaporator sets with out the loss of refrigerant along the lines of cascade 5

So could be used in a skulltail 2x CPU configuration or GPU/CPU or just CPU

As the chassis on this build is key this unit i may well be making changes to it for the best arrangements as the build progresses

The top and sides of the unit will be closed in this build

The evaporator is to be the new V8 from SoddemFX

This is the chassis so far tomorrow i will mount the 2x oil sep's

Very nice job, I love the idea, very thoughtful! I'm assuming you made that table thing yourself? Great job I'd recommend r14 for the third stage, but why not try an autocascade?

[marru]

Haha, nice assembly, but i wouldnt be anywhere that thing when the 3 rotarys are up and running.

Hot damn bazx, that looks awesome. Great idea on the chassis also, should really help with usability. Nice job welding that steel together

[n00b 0f l337]

So lets see, condensers going to be mounted to undersize of the "mobo" tray? I think your going to need more of those little pull stands

[godmod]

Make sure that you mount different wheels - WITH brake

What if this is a dual-purpose chassis though? It is after all a mobile assault unit, I think bazx is really creating the opposite of a flamethrower, a cold thrower! In all seriousness though, brakes would be helpful as stuff tends to get accidentally bumped from time to time and it'd suck to drag everything off the table and snap a suction line.

[bazx]

hehe these are not the final wheels just mock up once all the welding of the mounts is compleat its going of to be powder coated

yes nol the condencer will be under the table also the receiver

and most of the oil sep just the top of each sep will be visable from the top

[bazx]

Haha, nice assembly, but i wouldnt be anywhere that thing when the 3 rotarys are up and running.

why

Very nice idea bazx This is like a new program coming on the television. I like it.

i have missed the phase section and have wanted to build a new cascade for some time ron

so will be enjoying this build a great deal

@ nol i was thinking R14 myself never used it before so it will be a new refrigerant for me

as for auto cascade i will build one eventually but i am not ready yet

[killermiller]

It is amazing what people come up with. Weld a heavy duty dolly to it and you have mobility and stability.

[n00b 0f l337]

Trick to R14, have an extremely short unrestrictive captube on the r1150 stage, you need the capacity if your going ambient down to -90C and expect to transfer load well.

[[XC] 2long4u]

^^
Use the captube like an orifice tube?

[n00b 0f l337]

LoL no not that unrestrictive, just less then you'd normally use. Sdumpers has 5ft of .031" on second stage.

[Moc]

00 nozzle will be too small I think.
With 1kW load, -40°C 4K Subcooling and 35°C condensing temp, DanVen 5 says
02 nozzle !

[n00b 0f l337]

Why the monsterously huge compressors by the way? Thats going to be a hell of a 3 stage. Revolutionary idea too. Wish I could make that sorta stand

[Moc]

Move to Europe ....
-120°C @ 300W ?
Bazx, what do you want to hold in the third stage?
Perhaps a bigger Plate HX in the first stage would better...

[godmod]

Seems like nowadays 2 stage cascades become uncool and 3 stagers are cool 8)

[n00b 0f l337]

Well Bazx, Sdumpers, whom else got one? Ricky. Fuggers got his but I havent seen him use it lately...

[Moc]

And Fuggers is R4/5**/R1150/R1150 what is in my opinion quite useless.
R14 or R50, if you have a -100°C second stage (under load!) make sense.

[n00b 0f l337]

R50 requires too much flow, and chilling from 0 to -100C is horribly hard actually. The benefit of r1150 in third again is it acts almost like a water loop

Very nice project Bazx
