Cryogenic Dewar Cylinders: Superior Cryogenic Storage Solutions

Description:

Cryogenic Dewar Cylinders, also known as cryogenic cylinders or liquid gas containers, are meticulously engineered, super-insulated stainless steel vessels designed for the safe and cost-effective storage, transportation, and utilization of liquefied gases. These advanced containers are specifically constructed to handle the extreme temperatures of liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), and liquid carbon dioxide (LCO2). Manufactured in compliance with DOT4L standards, these Dewars ensure reliable, long-duration storage of low-temperature liquid gases, also serving as a readily accessible source of these gases for diverse industrial applications.

Cryogenic Dewar Cylinders

The robust and durable design of Dewar vessels, coupled with their extended holding times and integrated gas delivery system, makes them an invaluable asset in various industries. The integrated vaporizer allows for the continuous conversion of the stored liquid gas into gaseous form, supplying normal temperature gas (oxygen, nitrogen, or argon) at a flow rate of up to 9.2 m³/h. The system offers two output pressure options: a medium-pressure variant reaching 1.2 MPa and a high-pressure variant reaching 2.2 MPa, catering to a wide range of gaseous application requirements. For high-volume gas consumption scenarios, multiple Dewar vessels can be connected in parallel, or an external vaporizer can be incorporated, elevating a single Dewar's gas output capacity to as much as 30 m³/h.

Key Features and Advantages:

On-Site Gas Delivery: Provides convenient direct gas supply at the point of use, eliminating the limitations of traditional compressed gas cylinders. This system simplifies operations and eliminates the complexities associated with multiple cylinder handling.
Simplified Centralized Gas Systems: Allows for streamlined, small-scale centralized gas distribution, reducing infrastructure needs.
Superior Storage Solution: Leverages the inherent advantages of cryogenic liquid storage in Dewars:

Low Storage Pressure & Enhanced Safety: Operates at low storage pressures with multiple layers of protection, ensuring higher safety levels and ease of reliable operation.
High Capacity: A single DP175 Dewar cylinder holds a volume of liquid gas equivalent to roughly 30 standard compressed gas cylinders (for oxygen, nitrogen, or argon). This significantly reduces the need for frequent cylinder changes and associated costs.
Enhanced Gas Purity: Due to the direct vaporization of the liquid gas, the purity of the delivered gas is higher. This eliminates risks of contamination associated with multiple stages of filling, transport, and usage typical of gas cylinder systems, thereby ensuring a high-quality gas supply.

Processes

Cryogenic Storage: These vessels are designed for the safe containment of extremely cold liquefied gases.
Vaporization: Integrated and external vaporizers convert the liquid into a gaseous state for use.
Pressure Regulation: The vessels are equipped to maintain consistent pressure output.
