What cryocooler were you using in this video? I am having a hard time finding ones similar to the ones used to condense Nitrogen on TH-cam. All the ones I am finding look like they are part of a much larger system.
@@douglundy5755 I have not made a liquid nitrogen generator, so take my advice with a grain of salt, but I plan on making one in the future. But it looks like he is using a Stirling cycle cryocooler. It uses a piston to expand a gas and in turn cool a cold finger which is where the liquid nitrogen is condensed. What you can do is look for cryo vacuum pumps, they are ultra high vacuum pumps that use a cold finger to remove moisture from a vacuum system, however they can be used to make liquid air and nitrogen. eBay has many of these for 500-1000 used but you also usually use them with a compressor, which keeps helium on the inside of the cryocooler cold.
It is something like this: th-cam.com/video/ZSJFPb8030g/w-d-xo.html The actual cooler here was also bought off the shelf. It is very hard to almost impossible to make one of these yourself. And if you can it is probably cheaper to just buy one.
Nice work. Just remember you do NOT have pure liquid nitrogen but liquid air. It means there is some 20% of oxygen which has higher boiling temperature than nitrogen. It means that after some time the majority of N2 will boil off and the concentration of oxygen will be significantly higher. Take some risk precaution - don't use porous cardboard and similar easy burnable materials - they can start to burn very aggressively and rapidly they can even explode. There is a mixture used in the mines as explosive: liquid oxygen with one common material (I won't tell what it is to prevent some people to try it on purpose). Good luck with nice experiments. BTW, did you built the Stirling cooler or you bought it?
Hermann Göring You don't even need gas. Liquid oxygen turns organic material into high explosives. Just tossing a match into it can create some pretty crazy results.
The core component is bought off the shelf. And it is very hard to make this resonant stirling engine yourself. It is not outright impossible, but for most like 99,999% of people it is. And then it is probably not cheaper than buying one.
OK - can you at least tell me the manufacturer and model number of the cryocooler you are using here? I am working on a project of my own that requires liquid N2 (I will separate the O2 out with a separation membrane). Desperately need to get my hands on one to build my project. - thanks
tony cole They are not sold in any shops that I am aware of, only as surplus equipment salvage. It can condense most gases if they have a boiling point of at least 77 degrees Kelvin

What’s even cooler to think about is that not only does the processor become more easily cooled, but silicon is a superconductor at cryogenic temperatures, meaning at the boiling point of liquid nitrogen the electrical resistance of the silicon chip is exactly 0
@@awesomerthanyoutim20 Unfortunately, as far as I know, silicon itself does not become a superconductor at any temperature. Some highly boron-doped silicon apparently was a superconductor at 0.35K, but that's way lower than the boiling point of nitrogen. There are very few high-temperature superconductors that work at liquid nitrogen temperatures
th-cam.com/video/ZSJFPb8030g/w-d-xo.html They make them. The type is called "free piston stiring cycle cryocooler". Or "Resonant piston" or "linear piston"... something along those lines depending of the brand.
It's all basically a self contained unit, it runs on 0-110VAC approximately with 100W power usage. I am currently selling these for 6.25 bitcoins or $675 via paypal. PM if interested
So that's how a "Scroll" works... I always thought it rotated... Hey nerds. If you want to start messing around with cryogenics go and obtain a full 1-4 ton HVAC unit and then start doing your homework. Liquid air isn't a dream.... Dry the suction line on your compressor, feed it through a water cooled condenser after your orifice. No evaporator needed. Open loop.. Dry ice helps big time too. It's not Rocket Science although it appears to be on YT....
This is not a scroll. The spiral on the top is a dampening spring for a normal actuating piston. Scroll compressors use a rotating spiral that meshes with a static spiral and compresses the gas that way.
+Photon939 That would cost me less that $0.15 per day here in BC Canada. I thought the consumption would be much higher. Small amounts of liquid nitrogen run around $1 a liter (pure, filtered, delivered, 50L)

Can i use this to generate NOZ?
Inplix has the best handbooks and ready instructions. You can learn much from them and make it yourself.
I need it, to cryotempering my knife blade
More please. I would LOVE to make one of theses. Any plans anywhere? Thanks! ~Russ

Where do you buy it? Is this a Stirling Cryocooler? @@jackmclane1826
I've been trying to find a FPSC based cryocooler for the better part of the last 2 years :-\ Where did you get yours??
Where can I get this device for cheap? I found some on ebay, but there are so expensive for me :/

The cooler used in this video is a hybrid 98 by CTI Cryogenics. It's a common cryocooler
where can I contact you? I want one.
here
@@MrZanardimotors lol
You have of course not made the cryocooler, did you get it at ebay or so?
the exquisite beverage
Are you selling a completed unit, or plans so I have to take into consideration cost of parts as well?
Do you know what voltage the cooler runs on and where you got your autotransformer?
Could you share your design layout please I want to make lox for my rocket engine
Menace
What website do you go to buy the same type of cryocooler? Been looking can't find one. Can you use it with other gas?
tony cole They are not sold in any shops that I am aware of, only as surplus equipment salvage. It can condense most gases if they have a boiling point of at least 77 degrees Kelvin
Amazing! Could you give some details on how you built the cryocooler?
+Sébastien Bourdeauducq He made only the setup , nobody can built it.
"Nobody can build it" What?
Never give up

What voltage are you running this unit at?
could you farm argon with this?
How much time to generate 1 liter liquid nitrogen?
That's a sunpower cryotel right? How much was that?
How much liquid N2 is produce in 24 hours?? 1 liter??
thanks Juanma
What is the minimum temperature, and cooling power, if you have it?
How can it be -130°C ??? oxygen boiling point is -183°C and nitrogen -195°C...
could this be used to liquify methane ?

He didn't. The actual cooling unit is COTS.

i think this is liquid air ,not liquid nitrogen (although air have 78% nitrogen)
So that's how a "Scroll" works... I always thought it rotated...

Not scroll is, Stirling
It is a electricity-eater. The liquid air should be very expansive.
Gearldine Sweet Cryocooler uses 100w, costs $0.36/day to operate producing approx 1 liter of liquid air
+Photon939 That would cost me less that $0.15 per day here in BC Canada. I thought the consumption would be much higher. Small amounts of liquid nitrogen run around $1 a liter (pure, filtered, delivered, 50L)
