4 stage cascade

Actually I planned a 3 stage cascade, but now I want to try 4 stages. I started with the build last week.
Here is the old thread of the 3 stager: http://www.xtremesystems.org/forums/...ad.php?t=85580
I kicked the huge coaxil heatexchangers, and bought some nice plate HX. Furthermore I use only Danfoss compressors now.

1.stage
Danfoss SC21CLX
1,1kw condenser
3,6m 0,9mm captube (TC-36)
plate HX
R507a
Dixell XR10C Thermostat (PTC probe)

2.stage
Danfoss SC18CLX
Desuperheater
Henry S-5181 oilseparator
3,8m 0,9mm captube (TC36)
plate HX
R1150

3.stage
Danfoss SC15CLX
Henry S-5181 oilseparator
plate HX
R14

4.stage
Danfoss SC15CLX
Enthitzer
Henry S-5180 oilseparator
plate HX
chilly1 evap
methane

Last week I took the first pictures

Today I insulated the plate heatexchangers, but I have to take photos of it tomorrow.

A monster!:slobber: :slobber:

*Subscribed*
What sorta heat load you putting this on?

Monster! Is that the planned layout of the system?

good luck cold_ice :D

Methane :slobber: You don't have enough room around the HXs though. They will need LOTS of insulation. I'd want 6" around them.

How much does the whole thing weigh? 150+?

huge and sexy
this unit is a beast

oh my...

The 4 compressors alone are probably 160 lbs.

That's some awesome project you got planned there. I don't know if you just layed the components out to take piccys, but i'd put that thing on wheels before you braze it all together, or you'll never be able to move it with out a crane:D Good lucky:banana:

What temps are you expecting?

Looking good :clap:

methane

below -160°C? :toast:

But methane doesnt hold a load well i thought?

:eek2: Geez, Im floored. Nice work. I really want to see this fire. RussC

Thats fully sick. Good luck dude

Impressive cold_ice. I hope you beat the cascade records.
That that not you, is like altars to isolate the badge and the cpu. That if it is like they say for there is, that you arrived at -160º.
Luck with the project, I will follow it sincerely.

Greetings

Were those SC15CLX siamese twins at one point in their life? Can't wait to see the results of this beastly build.

:shocked: no way! Look at the size of...everything basically! Imagine the weight of that!!! I cant even begin to imagine the potential power of that!

I`ll be watching this!

Yep sure looks like it. Thanks for the cool pics.

I don't think the oil seperators will like being on their side like that.

LOL;)

Maybe they only have one leg.:D

how are you going to solve the r14 oil issue?

One compressor weights about 14kg, so I'm sure that the finished unit will weight 70kg or more.
I hope I can get -160°, I don't know if anyone ever used methane here at xs. But I'll give my best...
The SC21CLX is a new one, the SCL18CLX is from a condensing unit, and the two SC15CLX are from a Twin Unit. It separated the two compressors.
I have no idea how to solve the problem with the oiland the R14 though, there's not much info provided on the web about this. But I'll try it with the Henry oilseparator. We'll see how it works.

maybe other oil? Seeing the troubles chilly had with r14. I don't know if AB is suitable...
