This image also just called a bunch of random cats to my location.
Sounds great to me
you haven’t known true fear until you’re working with incredibly toxic chemicals or weighing tiny amounts and get the jumpscare of your life by one of these
This would be what we called a “gas pack” - which I think was a brand name, it’s been a while.
What I would have considered a ‘dewer’ was a vessel meant to hold cryogenic liquid that was not under pressure, basically a thermos of any number of sizes. And then there are these large vessels that can hold pressure. Some are only meant to have minimal pressure, because the user is interested in the cryogenic liquid inside, so the pressure is like less than 20psi if memory serves. The unit that is being referred to in this post was the aforementioned ‘gas pack’ that has an extra set of tubing that is wrapped in a around the inner of two vessels, so that liquid can gasify due to the heat exchange effect this coil provides, and allow this gas to be used by the customer. These are usually vented around 250psi, again if memory serves, so that the vessel doesn’t explode, ha ha. You can keep it from venting by isolating this gasification line, but that also reduces the convenience. It’d probably be best to store the vessel in a temperature controlled location to minimize the the chance of overpressurization.
I’m bored at work, if you couldn’t tell.
I used to work at a place that used a lot of nitrogen gas in manufacturing processes, as an inert control for sensors and stuff.
I don’t know how much pressure the big tank held, but there was a bunch of heat exchanger plumbing outside with a ton of ice around the first section.
It may have been a pump that would send the liquid to the heat exchanger. This is the way they fill the high pressure gas cylinders.
In this case, the nitrogen gas was plumbed directly from the big tank & heat exchanger to the various points of use.
Gotcha.
If my customer sent me this much detail, I would be a happy tech.
