What is GN2 Purge?

• GN2 is Gaseous Nitrogen. NOT Liquid Nitrogen (LN2).
• Creates dry atmosphere in the chamber.
• Consists of a solenoid valve, flow meter, injection tube, pressure relief vent.
• For low controlled humidity in humidity chambers (below 6°C dewpoint limitation of standard humidity range) .
• To eliminate condensation in temperature chambers.
• Lower initial cost compared to Dry Air Purge.
• Customer needs to supply nitrogen from tanks or a bulk system.
  • May not be an issue if customer already uses gaseous nitrogen for other processes.
• Rapid release of nitrogen gas into an enclosed space can displace oxygen, and therefore represents an asphyxiation hazard.
