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!

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

Hahaha this is far from casual :P

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

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

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.

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.

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!

Dude, you're just too good at it.

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.
