[labnetwork] Nitrogen generator cost question

[Gabriel Catalano]

Hi Nathan,

Our N2 generator system is Atlas Copco NGP+360 with a ZR110VSD compressor. Our current output is 70 CFM @ 120 PSI, 99.996% purity, and the maximum output is 145 CFM @ 120 PSI, 99.95% purity.  Equipment costs was ~$450K. I don't have the total for installation costs, but I am sure it was at least that much again since construction costs are particularly high for us. I cannot speak directly to why this make and model was chosen, but I suspect it just boiled down to correct capacity at a reasonable price from a reputable manufacturer.

We still use our LN2 bulk tank to supply N2 gas for UHP applications (> 99.995%), but our LN2 consumption has decreased by ~ 80% since our N2 generator came online.


Kind Regards,

Hello LabNetwork,



There have been a lot of threads on  the network regarding nitrogen generator systems for your labs to replace or supplement your existing systems.  There is a lot of positive feedback from those that installed N2 systems but no cost or size information was shared.  For those of you who have N2 generator systems, can you share the size and cost of your system?  Moreover, why did you choose the manufacturer you chose?



Thank you in  advance.
