We have nitrogen generators on four selective solder machines at one of the companies I work for. During the off-shift hours, the SS machine nitrogen generator is switched with a simple valve to refill empty nitrogen tanks. We then use the refilled tanks elsewhere in the building for other applications. We can measure the quality of the surplus nitrogen using the built in monitors. 
Thinking about getting rid of the liquid tank outside.

Hi Blair
What soldering processes?  We run two selective solder machines using a nitrogen generator, it is reasonably economical.  And pretty low maintenance.  At a previous job I looked at replacing the liquid nitrogen tank with a generator, big bucks but so is tank nitrogen.

cheers,

Hi Technetters,

We are thinking of switching from using bottled / tanked nitrogen for our soldering processes to getting a nitrogen generator. Looking for advice on what systems others are using and what they like / dislike about them. You can reply directly if you don't want to share with the list.

Thanks,
Blair

Anyone tried using the search tools from the web interface lately? I can't seem to get it to work.
