Similar to dry air purges, dry nitrogen purges pull moisture out of the air within a test chamber, but, instead of using a desiccant humidifier, rely on ultradry nitrogen (which has a dew point of 70 degrees Celsius). When injected into an enclosed workspace, nitrogen expands and adds pressure, forcing the remaining moisture out of the chamber.
