Nitrogen (N) is the dry, non-reactive workhorse of industrial gases.4 Supplied in high-pressure cylinders, Parolingas Nitrogen is essential for purging—displacing moisture and hazardous air from systems, which prevents internal corrosion and reduces fire/explosion risk. It is the ideal gas for pressure testing HVAC, refrigeration, and automotive systems to locate leaks without introducing damaging moisture (unlike compressed air). Its inert nature also makes it safe for use in food packaging and pharmaceutical blanketing processes
