I'm a mechanical engineer..My father works at one of the nitrogen filling stations nearby..I always wanted to know how these things work myself.. I've searched alot about nitrogen filling and safety but this video is the best of all videos that I've seen...Thank you guys for such a beautiful explanation of everything....Good luck😊
Great video covering the safety issues using liquid Nitrogen. Most ice cream operators or franchises will not discuss issues such as "burns" as they want to maintain the image of fun.
very informative, learned a lot. specially about safety, relief valve importance, and gas transfer diagrams. any information about rebuilding a Dewar please, in some of our containers we have noticed a vacuum break due to aging of o-ring in the double walls . i have a roughing vacuum pump plus diffusion pump
I want to mention one error. at 3.55 they say to not cover, tape or plug a pressure relieve valve. True although the port pointed to in the video is not a pressure relief valve, it's a vacuum port which should be covered to protect the vacuum from being disturbed. All I ask is that you point to the right part.
I have been working with liquid nitrogen for 5 years now with no formal training. 4:03 is a bit worrying, the pressure release valve is always freezing open and venting into the workspace.
4:02 Am I to assume that any pressure relief valve doing its intended job, should result in folks running away to call 911 ("emergency services")? These valves blow off a small amount of gas 8-10 times a day. A person can hear it, see it and because that gas is so cold there may be some frost formation....wait for it.....run for your lives!!! I have filled, delivered and serviced thousands of LN2 tanks and feel that this video gives enough good information to be worth watching but also includes enough bad information to cause problems.
should the room storing LN2 have ceiling exhaust or low level exhaust one says ceiling exhaust as nitrogen is lighter than oxygen to so extract effectively at high level; another says the when accidentally pouring some LN2 on the floor, low level exhaust can exhaust out nitrogen which is just been vapourized, not letting them even have chance to reach mid/high level of the room

Nice. Did you come across any repair technique for these containers?
Great video covering the safety issues using liquid Nitrogen. Most ice cream operators or franchises will not discuss issues such as "burns" as they want to maintain the image of fun.
This video is a great source of info. I have learned so much!
Pro tip: you can watch series at Flixzone. Me and my gf have been using them for watching all kinds of movies these days.
@Daxton Jace Yea, I have been watching on Flixzone} for months myself :D
Thanks a lot. I have learned a of liquid nitrogen from your video.

Hi jawad,Did you come across any information regarding this. I have a container having same issue. Any information on repairing instructions? Thanks
This video helped me alot, thank you very much!
Great video

Como es el proceso para producir el vacio en vessels
Nice
After closing the valve, how long does it take to built pressure in the tank?

What do you do with it?

GOOD
Did you take safety percsuition.not watching input
It could get stuck in your gloves
should the room storing LN2 have ceiling exhaust or low level exhaust
one says ceiling exhaust as nitrogen is lighter than oxygen to so extract effectively at high level;
another says the when accidentally pouring some LN2 on the floor, low level exhaust can exhaust out nitrogen which is just been vapourized, not letting them even have chance to reach mid/high level of the room
