2-Stage Cascade Project

[Obijuan83]

Its time for the next step in Phase Change cooling, so decided to build a 2 Stage Cascade.

It will consist of:

1st Stage

- Mitsubishi RE313VDMT Rotary 18k BTU/31.3cc
- 3KW Condenser 43x38x17CM
- 30cm Fan 25Watt
- 1.1L Receiver
- Danfoss TS2 TEV metering device
- Danfoss Eliminator molecular filter 1/4''
- Danfoss KP17 Pressostat
- Sight Glass
- Hi/Lo Manometers
- XMT7100 Thermometer
- R404a

1st and 2nd Stage will meet in an 40Plate HX

2nd Stage

- Mitsubishi RE207VHSMT Rotary 12k BTU/20.7cc
- Oil Separator 1/2''
- Danfoss Eliminator molecular filter 1/4''
- Danfoss KP17 Pressostat
- BartX 54mm Evaporator
- Tecumseh 2.35L Expansion Tank
- Hi/Lo Manometers
- XMT 7100 Thermometer
- R1150

Cascade will build in a 52x75cm Base Plate

You have some really awesome parts, good luck with the build!

Some progress

[Obijuan83]

Some electric components arrived

[eR1k]

Very clean looking, you're making good progress on the build! What temps and load are you aiming to achieve?

[Obijuan83]

Thanks, I would like to have -115C idle/-100C Load @ 350-400w.

A little more progress





And the thermostat for automatic power on the 2nd stage when 1st stage goes down to -40C

[Obijuan83]

First stage is ready





Also progress to 2nd stage, waiting for evaporator.

Man thats a very nice clean build !

[Charles Wirth]

I wish I put more time into making mine look nice, people are kinda shocked at how frankenstein mine looks. A really nice build

[Obijuan83]

Thanks, its a really compact cascade, a bit tricky to fit them all in 50x70cm base but I am used to work in limited space ( human abdomen )

[Obijuan83]

Time has come, only filling the 2 stages with r404a and r1150 remains

[Charles Wirth]

Thanks for the updates, very clean work. When I built my cascade 20 years ago, I waited until I had everything before I assembled and when I assembled it took me 24 hours to finish gassing the third stage.

[Obijuan83]

First stage up and running, fully insulated!

Beautiful Work. I always thought that phase systems should be totally encased because I was dedicating the unit to one build at a time.

[Obijuan83]

Finally after 4 months of building the Cascade its time for some numbers!

[eR1k]

Fantastic results and quality craftsmanship. How has the overclocking experience been for you so far with those temperatures?

Very clean build, looks fantastic and seems to perform very nicely! I am beyond envious that you can get ethylene, I've been wanting that for the last 20 years or so.
