What Are Cryogenic Vessels?
Cryogenic vessels are specially engineered storage tanks designed to store and transport liquefied gases at extremely low temperatures (as low as -196°C). These vessels are essential in industries such as medical, chemical, energy, and manufacturing, where precise temperature control is critical for safety and performance.
The Manufacturing of Cryogenic Vessels
DSW manufactures a full range of cryogenic vessels, including flat-bottom tanks, pressurized liquid storage tanks, Dewars, and cryogenic pumps. These vessels are designed for safe storage and transport of gases such as liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), and liquid carbon dioxide (CO₂).
Design of Cryogenic Pressure Vessels
Using specific design parameters, we engineer cryogenic pressure vessels to store gases safely at temperatures as low as -196 °C. Manufactured in China, these tanks, pressure vessels, and vaporizers meet strict international standards, including CODE 2000, EN 13458, EN 13530, ADR 2009, and ASME Section codes.
The vessels feature a dual-tank design: an inner tank constructed from stainless steel 304L (X5 CrNi 18-10) in accordance with EN 13458 standards, and an outer tank made of carbon steel. The annular space between the tanks is filled with perlite insulation and reinforced with high-vacuum technology for superior thermal performance.
Key manufacturing specifications include:
- Inner tanks engineered to store gases at temperatures down to -196 °C.
- LIN, LOX, and LAR cryogenic storage tanks with capacities from 300 to 80,000 gallons (up to 50 tons).
- Vaporizers available in ranges from 700 SCFH (20 Nm³/h) to 35,000 SCFH (1,000 Nm³/h) per unit.
- Liquid CO₂ storage tanks offered in sizes from 3 to 50 tons.
Dewars and Cryogenic Vessels
Dewars and cryogenic vessels provide reliable solutions for the safe handling and long-term storage of gases such as liquid nitrogen, as well as corrosive substances like chemicals and acids. Built with high-density materials, they offer strong resistance to chemical attack and corrosion.
These vessels are available with wide or narrow-mouthed openings, making it easy to transfer or pour liquids without spillage. They are widely used in research, medical, and industrial applications where precise and dependable gas storage is essential.
Available in a range of sizes and configurations, dewars and cryogenic vessels can also be customized to meet specific requirements. Advanced insulation technology ensures stable temperatures, protecting the integrity of the stored substances over time.

Cryogenic liquid tanks store gases in liquid form and are customized to meet specific pressure requirements. They feature an inner tank made of stainless steel 304L (X5CrNi18-10 according to DIN 10028-7 or equivalent) and built to EN 13530‑2002 standards. The outer tank is made of carbon steel and also complies with EN 13530:2002 standards.
These tanks maintain precise pressure conditions while safely storing both liquid and gas phases. They are essential in industries that handle and transport cryogenic liquids such as oxygen, nitrogen, argon, and other gases. The dual-tank design enhances durability and safety, ensuring reliable performance in demanding environments.
DURA LIQUID CYLINDERS
DSW offers a complete line of Dura liquid cylinders. The Dura liquid cylinder is designed to transport, store and deliver oxygen, nitrogen, and argon as a cryogenic liquid or gas. Dura cylinders are vacuum and super-insulated vertical-type liquid cylinders with an in-built vaporizer that allows storage of cryogenic gases like oxygen, argon, nitrogen, and medical oxygen at a very low temperature ranging From -183deg C to -196 deg c. (Cryogenic Liquid Tanks)
CRYOGENIC PUMPS
Our cryogenic pumps handle oxygen, nitrogen, and argon liquids directly from storage tanks. They compress these liquids to high pressure and then support the vaporization process. In this stage, an ambient air vaporizer converts the compressed liquids into gases.
After vaporization, the high-pressure gas flows into cylinders through a manifold or directly into a customer’s pipeline. This flexibility ensures efficient gas distribution for industrial, medical, and research applications.
We design our pumps with strict safety and performance standards in mind. Their advanced engineering and robust construction deliver reliable results even in demanding environments. As a result, businesses worldwide trust these pumps for efficiency, durability, and long service life.
