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.
