    2-Stage Cascade Project

    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

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

    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

    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 )

    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.

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

    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.
