Liquid Argon Gas
DSW provides high-quality liquid argon tanks or cylinders for cryogenic storage of liquid gases, including argon, carbon dioxide, nitrogen, oxygen and helium.
The tanks range in capacity from 3,000 to > 100,000 litres and come with standardised working pressures of 18, 22, or 36 bar respectively.
The 20-foot ISO framework type tank container is applicable to Intermodal transportation including marine, highway, and railroad transportation. With its overall dimensions conforming to the ISO standards, the tank container has a rating for as high as 9 high stacking loaded.
A typical system is composed of the following: a cryogenic tank, one or several vaporizers and the necessary piping for filling, vaporizing. In principle, the liquid argon tank looks like a vacuum container. The cryogenic tank is designed to keep the heat away from liquids contained within the inner vessel. Vaporizers change liquid argon into gaseous form. The pressure of the gas that is fed into the process can be controlled by a pressure control manifold.
Liquid argon is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires special equipment to store and handle cryogenic liquids.
Air separation plants produce argon through the continuous cryogenic distillation of atmospheric air. The cryogenic liquid is recovered from the argon.

| DSW offer argon gas in high-pressure gas cylinders and liquid argon dewars in a variety of sizes. Argon is used to an inert shield gas to enhance arc stability and characteristics of gas metal arc welding. It is also the primary gas for the Gas Tungsten Arc Welding (GTAW) process. | |||
Argon may be referred to as “PLAR” (pure liquid argon) or “CLAR” (crude liquid argon), or by its chemical designation, “Ar”. Crude argon is usually thought of as an intermediate product in a facility that makes pure argon, but it may be a final product for some lower capacity air separation plants which ship it to larger facilities for final purification. Some crude argon is also sold as a final product for uses that do not need high purity oxygen (e.g. some steelmaking and welding applications).
DSW offers a range of high purity liquid Argon to suit your application and process needs.
