Nitrogen Gas Barrier System

Anywhere there is fear of explosion — or one gas has to be kept separate from another — an N2 curtain is used. In enclosed areas or even open chemical plants, nitrogen gas is blown between gases to create a barrier. On Site Gas has been providing nitrogen gas barrier systems to the chemical and oil industries for years without a failure. Our highly reliable PSA and membrane nitrogen generators provide gas barrier protection in classified areas, safe areas, and even splash zones on ships, platforms, and in plants all over the world. Our experience in weather and explosion proofing is designed to provide a nitrogen curtain system in any climate, any location and any extreme.
