Cascade for John

[LukeXE]

Hi my friends

Few days ago John asked me about building for him cascade. I thinked about it and decided to do normal 2 stage cascade, but not in 100% normal.

I want to use ethylene as low stage gas, but thinked about high stage. Better HX temps = much better load temps on evap, am I right ? I will do first stage autocascading, even with -55*C under load on HX temps should be very good and I will have reasonable pressure to condense properly ethylene

It`s not problem for me doing first stage autocascading, like normal stage, but a little bit more pipes and phase separator and those are all differences, so why not try ?

For I stage I will use my autocascade just rebuild it a little bit and add second stage with 1HP rotary compressor and plate HX from Gray We will see how this baby will perform



and HX I will use...




tomorrow I will go for small shopping, I`ll buy some brazing rods, pipes, second highpressure cut-off switch and some more stuff

Stay tunned

BTW, we are thinking about 3 stager, so then we could use R14 as well !
