DSW designs and manufactures cryogenic argon tanks for safe, efficient storage of liquid argon (LAr) in industrial applications. Built with vacuum-insulated double-wall construction, these tanks minimize heat ingress, reduce evaporation loss, and ensure stable long-term storage and supply performance.
Available from 3m³ to 100m³+, our liquid argon storage systems are widely used in industrial gas distribution, welding production, semiconductor manufacturing, metallurgy, and precision engineering environments requiring continuous argon supply.
What is Cryogenic Liquid Argon Storage?
A cryogenic argon tank stores argon in liquid form at approximately -186°C. This reduces gas volume by around 840 times, making bulk storage more efficient and economical compared to cylinder systems.
Each tank includes a stainless steel inner vessel, carbon steel or stainless steel outer shell, and high-vacuum insulation to ensure low thermal loss and stable performance.
