I’ve been asked to look into centralizing a nitrogen gas utility that is used by a number of laboratories within a manufacturing building. Currently, the individual users that need nitrogen gas use something like this within the lab spaces: https://ph.parker.com/us/en/nitroflow-lab-mobile-nitrogen-gas-generator-for-lc-ms
The concerns from my client are: they are too loud, the heat buildup within rooms is excessive, and the PMs on the devices are getting to be a bit much (in terms of cost and downtime).
I am looking into replacing all these smaller generators with a central source of gas cylinders (dual bank with switching regulator) or maybe one larger generator unit. I’m not familiar with these nitrogen generators and am wondering if people have some ideas why this is preferable to a cylinder bank? My experience from college and other lab clients has been that cylinder banks are used in favor of these types of generators. Unfortunately my client contact is new and doesn’t know why the generators were used vs. cylinders from the get go.
My hunch is that capacity might be the (perceived) problem and that’s why the generators were chosen, but I’ll be digging more into the problem soon.
