Hey Guys

Unloaded -110
Loaded @ 250W about -95

Client is happy afaik :)

Ill try to take some pics when i meet him.

We have similar unit's @ work too, cryo compressors with helium charged. 20Kelvin temps but very low load offcourse at those temps

good luck with the project !!

hey guys,

shortened the captube with 10cm so i have now 2.9meter, i was testing and the rotary went down because he was running to hot. need to install a extra fan i suppose.

i was waiting to...

Didnt measured the first stage temp on the picture, it's basetemp between evap and heatload.

I have some LCD tempsensors that i will install when the case is ready...

Hey Sdumper,

thanks ! yeah it's been a while that i did some building :) happy to see old faces around ! ...

Did some tests with a shorter captube, about 3meters now.

Hey gray,

Temp is measured @ evap, i think the captube is still a little too long, will cut some more tomorrow.
Yeah happy indeed that it holds the load !

grtz,
Jort

First results !!

-60 measured @ evap with 260W heatload...

Going to cut some extra captube, currently have 3,1m of 0.031

see you soon !

i want to participate also when it's a summer compo :)

Update :

Installed SLHX in 2nd stage, and shorten the captube about 15cm. getting vacuumed when i speak. test results in an hour :))

Hey ,

the smalest R507 compressor here is TL4CL 3,8CC displacement... what do you think ?

gr

Hey Gray !

I soldered the captube and the result was stunning :) could hold the evap @ -10 with a heatload of +/-300W. the fans on the condensor are medium flow so results can be improved. but i...

I am active and i live in belgium so 230V :)

Hey gray,

Thanks in advance !

I ordered a SLHX for the 2nd stage so i don't need to swap the other one.

I'll test again when the SLHX is installed and i'll shorter the captube. was my tought...

Hellow,

Did a first Real live test on a cpu today, first experience with cascade...

Results where not what i expected, -50 unloaded and -35 loaded @ 8core cpu @ 4.5 Ghz.

I used 0.9 mm...

Yeah gray your right, but i didn't have armaflex glue here and armaflex idd isn't that expensive, it looks a little bit less sexy idd :)

Thanks again.

Yeah subcooling is very important indeed, i wanted to place a Suction HX on the Ethylene circuit but i tought to keep the volume as low as possible ( static charge)

Ill try to do...

Hehe thanks for the explanation man ! your surfing the XS for years now and i am seeing you as a mentor to hold on and try new things ;) The Ultimate Vapo mod catched my attention 2.

The High...

Yeah w'll see when i put that thing under load, the Rotary does a very good job pulling the HX very cold, but idd i was suprized by the High pressure of the Ethylene ...

Incredible feeling to...
