ice-man cascade

Got a request for a -100° cascade some time ago, tomorrow it will be shipped to Sweden. I took longer than expected to get it ready, because of job and a lot of other work but finally its ready. And the most important part is good performance :)

Parts:
1.stage:
Danfoss SC21CLX
Luve 139 condenser(1,39kw)
0,88l receiver
Castel sight glass
Castel filter
Danfoss TS2 with 00 orifice
Plate HX
R507

2.stage:
Danfoss SC21CLX
ND50F Desuperheater
Danfoss OUB1 oil separator
Danfoss pressure control
R1150

Results:
-40°C to -45°C HX temp (today a bit lower because of only 15°C ambient)
-105°C w/o load, 200w -96°C
I hope the owner of the unit can approve this temps :toast:

Ready for shipping on pallet

http://www.extremecooling.net/random..._erixon/20.jpg

Clean build, nothing but A-quality parts. Very nice :D

Very nice as usual cold_ice :D!

:D Do not ship to sweden - invoice has changed, I'll give You my adress....:p:

How long captube you used on 2nd stage?

I cant really remember what length I used, but I think it was about 350cm of 0,9mm captube.

did u pack the box in another box? i would be a bit scared if that was coming to me, look at jinu...

nice as usual!!!

I see no danger in shipping that one. it is on a pallet dude ;)
Only fork Trucks will transport it :)

Nice and bloody clean!!! Not so sure on the suction line but as long as boa constricter but still nice!

Another beautiful work!!:toast: :clap:

You got it :) Shipping is expensive this way, but too much danger of damaga when you ship it in a normal package with common parcel service.

Thx for the nice comments!

Ive seen units shipped on a pallet get a nice "tap" from a forklift truck when the operator has been rushing and has gone forward on the pallet before the forks are fully down :eek:
Never underestimate the brutality of shipping a unit! I hope it arrives damage free.

G

so nice unit, simple and effective. Industrial quality my friend!

Looking forward to get this baby home, I'm praying that it will arrive damage free!!

Hmm, I woulda thought you would need some stainless steel braiding on that flex line to handle 1150 safely?

EDIT lol nvm:am:

Look at the second picture, the line has stainless steel braid.

Erixon: I shipped a few cascades like this one and all arrived with no damage at all :)

i ve made 2 or 3 casacde with ethylen , and static pressure with R1150 was around 5 bar , no need braid so...

th flex i use , i can put around 20 bar without braid :toast:

Yes thats true. Braided flex line isn't really needed because pressure won't get higher than 10bar at low side. But its better to have a braided line in cascades :D

realy nice really :banana::banana::banana::banana:ing nice buid there, i want uit, where is it going to be shipped from? i cant get my cascade from norway..but that cascade travels around the world:

Excellent work here cold ice!!

Not around the world krullet, from austria to sweden !!

i love ur clean work!!!!!!!!!

is the case by littledevil??

do u just turn both compressors on together or do u have different switch for 1st and 2nd stage??

He would have to let the HX cool to temp first before turning on the second stage compressor. Otherwise the 1150 won't condense and his pressures will skyrocket!

Thx!

the_new_guy: The case and the layout was designed by me, littledevil produced these awesome cases for me. He made me a good offer so he got the job.
The second stage compressor is turned on by the thermostat automatically when a temperature of -25°C on HX out is reached. So you only start the first stage with the switch. Pulldown on first stage is pretty fast, I would bet about 3 minutes after starting the unit and you have -100° on the evap.

Good stuff Cold_ICE.
Skirms, I probably use one of strongest unbraided suction line that is available around for single stage (185psi working pressure 270 psi test pressure). However, considering the dangers involved on 2nd stage, I can't imagine selling units with non braided suction line in case of failure on 1st stage. Pressure cut off usually are set around 300psi, manual pressure relief around 350 to 400 psi. Most of components are rated working to 300psi and suction line will be the weakest link bringing the total number down.
