​Cryogenic Dewar Cylinder

Cryogenic Dewar Cylinders: Your Solution for Liquid Gas Storage and Delivery

Cryogenic Dewar Cylinders are meticulously engineered, high-performance containers designed for the safe and efficient storage, transportation, and dispensing of cryogenic liquids such as liquid oxygen (LOX), liquid nitrogen (LN2), liquid argon (LAr), and liquid carbon dioxide (LCO2). Constructed from premium-grade stainless steel and featuring advanced super-vacuum insulation, these vessels minimize heat transfer, ensuring exceptionally long holding times and reduced boil-off rates for your valuable cryogenic fluids.

Built for Reliability and Economy

These robust vessels are manufactured to meet stringent DOT4L standards, guaranteeing both safe and economical transportation and storage of cryogenic liquids. They are ideal for on-site storage and supply, catering to a broad spectrum of industrial and laboratory applications where low-temperature liquefied gases are required.  The design focuses on durability and dependable performance, making Dewar vessels a cost-effective alternative to traditional high-pressure gas cylinders.

Integrated Gas Delivery System for Seamless Operation

A key feature of the Cryogenic Dewar vessel is its integrated, on-board gas delivery system. This includes a built-in vaporizer (carburetor) that allows for continuous delivery of normal temperature gas (oxygen, nitrogen, argon) at controlled flow rates.  These systems can provide consistent gas output up to 9.2 cubic meters per hour (m³/h), with pressure options including a 1.2 MPa (medium pressure) or 2.2 MPa (high pressure) variant to match application requirements. This inherent capacity makes them suitable for direct supply to many processes.  For applications requiring larger volumes, multiple Dewar vessels can be connected in parallel, or an external vaporizer can be added to increase delivery capability up to 30 m³/h per vessel. This modularity ensures scalability for a wide variety of needs.

Key Benefits of Cryogenic Dewar Cylinders

• On-Site Gas Supply:  Dewar vessels facilitate convenient, direct gas supply at your point of use, simplifying operations and reducing the complexity of gas distribution. Their functionality is similar to traditional compressed gas cylinders but with significant advantages.

• Simplified Centralized Gas Systems: Dewar vessels simplify the implementation of small, centralized gas supply networks, reducing reliance on individual high-pressure cylinders and streamlining infrastructure.

• Enhanced Efficiency:  Using cryogenic liquid as the source provides numerous operational benefits.

• Improved Safety: Low storage pressures and multi-layered safety devices ensure superior safety and operational reliability.  This reduces the risks associated with high-pressure gas cylinders.

• Large Storage Capacity:  A single DP175 Dewar vessel stores an amount of gas that would be equivalent to almost 30 traditional compressed gas cylinders of the same gas (oxygen, nitrogen, or argon). This substantially reduces cylinder change-out frequency and associated logistical costs.

• High Purity Gas Delivery: The direct vaporization of liquid gas minimizes the risk of secondary contamination associated with multiple transfer steps in the supply chain of traditional gas cylinders. This ensures higher purity of the delivered gas, crucial for many sensitive industrial and scientific applications.
