Dewar Cylinders

Dewar Cylinders, also known as Cryogenic Dewars or liquid cylinders, are vacuum-insulated containers designed for the storage, transport, and controlled supply of cryogenic liquids such as liquid nitrogen, liquid oxygen, liquid argon, and carbon dioxide (CO2). Available in different capacities and configurations, these cryogenic vessels provide a practical solution for laboratory, medical, industrial, and specialized gas supply applications.

Types of Dewars

Dewar cylinders are one type of vacuum-insulated cryogenic storage equipment. For a broader comparison of cryogenic tanks, dewars, and other storage configurations, see our cryogenic tanks guide.

Dewar Sizes and Capacities

Dewar cylinders are available in different capacities to accommodate laboratory, medical, industrial, and gas distribution requirements. DSW Industries offers cryogenic liquid cylinders in approximately 50–230 litre capacities, with configurations selected according to liquid type, operating pressure, withdrawal method, and mobility requirements.

High-Quality Stainless Steel Construction

Our cryogenic storage vessels are crafted from premium stainless steel, providing durability, corrosion resistance, and long-term reliability. This construction keeps your cryogenic liquids secure during storage and transport.

Standards and Transport Options

Depending on the model and intended market, DSW Industries can provide cryogenic liquid cylinders designed or certified to applicable requirements such as ASME, DOT, TPED, and ADR. Available capacities and mobility configurations vary by model, with options including casters and dollies for easier handling.
