There is absolutely no ghetto in that cascade. All high quality to the last detail :) There must be about 100€ wotrh of armaflex in there :D

Yes I used alot of Armaflex for this cascade :D
Today I finished the 4th and last stage. I have a small leak at the Rotalockvalve at the expansion tank. Will fix that as soon as possible.
The suction line has very thick Armaflex 32mm on both sides. All the other should be visible at the pictures.
Now only some of the insulation, the charge, the tuning and the eletrical wiring is missing.

that thing is a monster! can't wait to see some more frost, gl with that!
awesome ;)
this system is absolutely awesome. Can't wait to see it running!
wow i would never have enough patience to do something like that, simply insane
that thing must wiegh over 500lbs!
wooo good luck!
My question is simple:
What do you plan to do with it, and how will you move it?
^^^ and how much are you gonna sell it for?:D
Obviously overclock and obviously a fork-lift.Quote:

maybe he should test it on th beer first.:D
Much more than you can afford, that's for sure :p:Quote:

you havea pretty beautiful mess going on there ice.
OMG :OOOOO :eek2: :worship: :worship: :worship: :worship:
this is sooo sweett.... my god, this is the cascade of my dreams !!!:shocked:
Congratulations man, i cant wait to see the results !
:toast:
berkut
so..... how is it going?
:toast:
Thx for all the nice words :)
Yesterday I charged the unit. Continued the work today, the first 3 stages are running. First stage is running very nice, temp only rises when starting the second stage for 1-2 minutes, than back to -20° rock stable. Seems that I have alot of R23 in the second stage.
I hope the condenser of the first stage is big enough (1,1kw) because the whole surface get hot today. And only the first 3 stages are running...
The liquid line has about 40°C, although air temp near the cascade is 35-37°C. The heat output is enourmous, normal room temp is 26°C, and near the cascade it 32°C.
Second stage is running fine too, only struggling a bit when third stage starts. But HX-Out Temp is back to -67° in 1 minute.
The third stage doesn't run as I want at the moment. Yesterday I got -125°C HX-In but today i got only -75°C?? Will look tomorrow whats the problem here.

this realy is one of my favorite projects :)
Nice to see how all the hard work is comming to a result slowly but steady.
hope to see some evap temps soon.
here you go, have a beer :toast:
what a huge cascade :eek:
such a cold making monster :slobber:
good luck cold_ice :toast:
Very impressive... :D
you don't have floodback anymore?
No floodback anymore. I will get a bigger condenser next week. I think LuVe STVF 194 might be a good choice. Has 1,93kw at Delta T of 15K. The current one has only 1,1kw. I hope I have enough space for the bigger condenser...
I want to get the second stage down to -75° loaded.
I think your condenser should be much bigger than it is.
1.93kw might not be good enough... Unless when the system equalizes the heatload will be smaller.
You get quite a lot of frost on the sucktion lines next to the compressors. You could reduce the flow a little. This usually makes a big difference for me. Especially in higher stages.
What do you think what size of condensor I should get? Next week I make a new order at HVAC shop so I will order a new condenser.
You need to add up all the electrical wattage of the compressors ,then add the heat load.
The "heat of compression" will be your biggest load,add that plus the load on the evap,say 300 watts plus add some for line loses. that will give you your condensor load that must be rejected,
Very nice work
1.93kW isn't the maximum rating of the condensor. It is how much heat will be removed at a deltaT of 15K . At 20K the condensor is already able to remove much more heat.Quote:

Estimated that the compressor itself will add 500watt, the condensor is now removing 1300-1400watt. With the fourth stage + cpu added, I would say another 500watt is added, resulting in 1800-1900watt for the condensor and 1300-1400watt for the 1st stage compressor.
Since the condensing temperature now is 45 degrees and ambient is 26 degrees with the 1.93kW condensor and 4 stages active I would say you get a condensing temperature between the 40 and 45 degrees. If it is 40 degrees you gain some capacity but since the compressor still needs to remove 1300-1400 watt I think the first HX temp will rise up to -20*C maybe even -15*C.
With the SC21CL I think every 5 degrees in condensing temp you lower you gain about 200watt of capacity which is something like 3-4 degrees gain. If you want to condens @ 35*C I think you need a condensor in the range of 3kW or something but that's a geuss not really based on anything :D
I hope this rambling helps you anything :D
