The New Anaconda Kingdom AKA My 3 Stage Cascade!
My New benching palace:

See that the high stages are all located one side now, at the window, to throw the condensing heat outside, finally, no more sauna room!!
Right here, you see the Anaconda nest... 4 Heat Exchangers....

1 is home-made winding pipe in pipe, almost 7m, its supa ghetto, Polyurethane foam is banned here now, so back to Armaflex insulation! This is for CPU first stage, which connects to CPU middle stage Heatexchanger right below. On top you see a fanless condensor, thats the de super heater for CPU middle stage, good to have, cos a lot of R1150 needs to be condensed!!
The 3 evap cooling heads right here... benching section.

My CPU evap gets a major upgrade, much thanks to my friend Xu Gang and Susie from China!! He made me this awesome evap head!!

Its way too massive, i even trimmed some fins off to use aq smaller outer cap. But to cool it by itself is a huge heat load... but once cold, it stays there for frkn long...
Here are the 3 low stages for CPU and gpu1 and 2, with oil seperators right beside:

The 3 High staqes and 1 Middle stage for cpu area... 4 x rotaries 1HP each!!

Of course oil seperator for middle stage as well!

Much much thanks to my friends for building me such a beautiful Control Panel!!! So good to have all switche controls over here!!

GPUs Cascades is usual R22 stage 1 and R1150 Stage 2
CPU Cascade:
1st stage: R22 + dash of R290 - 1.3m of 0.31" cap tube , yes had to rim so short, the heat load on 1st stage is immense, trying to condense so much R1150 on middle stage, and R1150 of 3rd stage and then also CPU heat load.
Under fulll load running, -26C or so.
2nd stage: R1150 + dash of R290 - 1.65m of 0.31" cap tube.... Under load, it's about -80C to -85C...
3rd stage: R1150 - 1m of 0.47" connected to 0.5m 0.31" to evap head :D low hi side preesure with -80C condensing temps, so short cap tube for good enough flow!! With ~ -80C condensing temps, this is the length you want to maintain good flow for kentsfield loads with R1150!
The evap is so huge, cooling it down itself is huge load, so i need to wait till its cold before turning on PC, if not middle stage will be overloaded with heat load of cooling evap and pc all at one go. overload is no good, hi side pressure of 3rd stage rises rapidly due to rising condensing temp, flow gets too fast for short cap tube and liquid slugs the comrpessor. just an issue if cold bugged cpu.
i had the probe placed at evap exit which is bad side to monitor... evap exit is more liek ur usual suction line close to compressor due to evap size. but cpu evap base is around -107c to -110c load or idle, as evap is so huge. suction preesurfe is vaccumm under load, like 5 to 7hg good stuff,,,, R14 wil be nice to switch to now :D
