The most popular cylinders are constructed of chromium-molybdenum steel, aluminium, or a composite depending on the properties of the gas, as well as the application. Cylinders sizes vary in both dimension, as well as internal volume, with capacity ranging from less than 1 to over 100 litres. However, when filled under pressure, the content in a cylinder can be in thousands of litres. Cylinder availability is subject to the product properties, desired pressure and legislative requirements.
Besides cylinders, another supply form are gas generators. The specialty gas generators that Linde offers produce hydrogen, nitrogen or zero air. Generators are frequently used as an easy and efficient supply source in laboratory environments with a constant gas demand.
For liquiefied air products such as Nitrogen, Argon or Oxygen and Carbon Dioxide supply containers would include portable cryogenic containers and dewars. Linde offers a special supply service for such liquefied substances, called CRYOSPEED®.
Gas cylinders are considered pressure vessels, and therefore governed by local authority rules and regulations. Some are non-returnable and others are recyclable. For information on cylinder sizes available in your area, please contact your local Linde representative.
