Airgas, an Air Liquide Company, provides dewars to meet specific customer needs. Coming in many different sizes for various applications, our dewars are designed to maintain extremely cold temperatures for cryogenic storage of liquid gases—including nitrogen, oxygen, argon and carbon dioxide.

Safety first
Your safety is our priority. That’s why all of our dewar sizes, materials and valve types are determined by CGA, DOT and TC guidelines. We draw on decades of industry experience to determine which gases can be safely contained and transported in which type of liquid gas cylinders.

Ensuring gas stability
Beyond meeting safety guidelines, we also ensure gas stability through design and materials of construction of valves and other equipment. This helps protect the integrity of the gas against corrosion and certain chemical reactions.
