Should be good. One hell of a comp there.

What happened too the other cascade?

 

[Mr. Smith]

Is this unit for you or is this one to sell?

I still can't get over how you guys just casually build these like I'd build a w/c loop.

My hat is off!

 

[NoL]

Not for sale; yet, becuase its experimental in a bit of ways.

Hahaha this is far from casual

The old cascade was charged with co2 in low stage, hit -58C and was abandoned and parted out. (-58C is lowest you can get; period; with co2.)

 

[NoL]

Here's diagram minus expansion tank, filters, and a few other things.

Wow, I can't wait to see the final unit, autocascades, are the ultimate in elegance imo.

 

[NoL]

And here's the first heat exchanger (took only 10 minutes or so to build and coil!)

Dimensions of HX are 10" tall, 5.25" wide. Only 1.5" tall as well!

Nice and small, phase sep will most likely be inside of it before I apply insulation.

 

[NoL]

Sorta layout, at least with HX standing in front of condenser with phase sep in the middle. The accumulator/expansion tank with hand valve will go on top of the condenser though.

I'm also going to try and get some butane or isobutane, so that I can do some experimentation with r600/a, r290, and co2 while I save for the r23 and regulator.

 

[NoL]

HX on the left (well either might be HX), nicely spiraled up almost, bit of a trick with the pipe bender when you got 3/16" inside. But I got it!

Nice and toight!

 

[Mr. Popo]

Dude, you're just too good at it. :nono:

I managed to learn and forget, and you... you are a busy phase builder.

Just wait, one day you and me will have talk, you'll teach me everything you know.

 

[NoL]

You can always message me and I'd be glad to teach you waht I know.

 

[Brettbeck]

Good luck with the build !

 

[llwyd]

One on the left tbh, looks neater

 

[NoL]

Heh I'll be using em both, both will look the same insulated up

 

[NoL]

Plotting the tubes now for the rest of the system, trying to find a clean source of butane as well.

 

[NoL]

Updates ! ! !

Piped and plumbing is getting done. You can see the idle/load valve with bypass linked to the expansion tank.

Here's some pics, its all loose and not brazed so it was a bit hard to get it all to stand still!
