Used Nitrogen Generators & Surplus Nitrogen Generators

Holtec systems often replaces nitrogen generators produced by other manufacturers, and sometimes our customers ask us for assistance in disposing the used equipment.  We do our best to help our customers, sometimes purchasing the old equipment for refurbishment, and sometimes simply assisting in finding a new home for a nitrogen generator that still works.  

This translates into substantial savings for our customers.  The level of refurbishment varies from new or “as is” to completely re-worked, improved, and warranted systems.  Currently, we even have new surplus equipment and in-stock inventory that has never been used.  Please see below for a list of systems that are currently available:
