Cryogenic Vessels

ASME tanks get their name from the American Society of Engineers. These cryogenic vessels are designed for permanent installation on a property.
Because they have thicker steel and are not exposed to the same hazards that mobile DOT cylinders are, recertification is not required.
ASME tanks are measured in gallons. Common tank sizes range from 120 gallons to 2,000 gallons.
The capacity of DOT cylinders, on the other hand, is measured in pounds of water. They might range in size from 5 pounds to 420 pounds.

Cryogenic Vessels


DSW International offers a full line of liquid transport tanks for liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR) and liquid carbon dioxide (CO2) service. Tanks are produced to store the inner gas, at -196 ºC or at a less temperature, depending on different design parameters.

Cryogenic Liquid Tanks

Cryogenic Liquid Transportation Tanks are used for the storage and transportation of the gases in liquid form. These Tanks are produced to store liquid and gas according to the pressure condition requests of the customers. The inner tank is made out of stainless steel 304L (X5CrNi18-10 AS PER DIN 10028-7 OR EQU) & design code EN 13530 – 2002, while the outer one is made out of CARBON STEEL & design code EN 13530:2002.



DSW offers a full line of Dura liquid cylinder and cryogenic vessels. The Dura liquid cylinder is designed to transport, store and deliver oxygen, nitrogen, argon, as a cryogenic liquid or gas. Dura cylinders are vacuum and super insulated vertical type liquid cylinders with in-built vaporizer which allows storage of cryogenic gases like oxygen, argon, nitrogen, medical oxygen at a very low temperature ranging From -183deg c To -196 deg c.(cryogenic vessels)

CRYOGENIC PUMPS (Cryogenic Liquid Tanks)

DSW offers a full line of Cryogenic pumps for Oxygen/Nitrogen/Argon Liquid from the cryogenic tank is compressed to high pressure in a cryogenic liquid pump. It is then vaporised in an ambient air vaporiser to produce gaseous oxygen/Nitrogen/Argon. The high-pressure gas then can pass into cylinders via the gas manifold or fed into a customer’s product pipeline.
