How Vacuum-Perlite Insulation Works
Liquid argon must be maintained at cryogenic temperatures to remain in liquid form. Heat entering the storage vessel can cause part of the liquid to vaporize, increasing pressure and resulting in product loss or the need to manage boil-off gas.
A vacuum-perlite insulation system helps limit this heat transfer. The space between the inner and outer vessels is filled with expanded perlite and evacuated to reduce heat transfer through the insulating layer. The combination of the vacuum and insulating material helps maintain storage conditions and supports a lower static evaporation rate.
Actual evaporation performance depends on the tank’s insulation design, ambient conditions, operating pressure, liquid fill level, and the method used to measure the rate. Buyers should review the manufacturer’s specified test basis when comparing different tank models.
Applications
Vertical LAr cryogenic storage tanks are used where liquid argon is delivered in bulk and stored before being transferred to downstream equipment or converted into gaseous argon by a suitable vaporizer.
Typical applications include:
- Metal fabrication and welding: Supplying argon for shielding and other industrial welding processes.
- Metallurgy and metal processing: Providing argon for selected inert-atmosphere and process applications.
- Electronics and advanced manufacturing: Supporting processes that require a controlled argon supply.
- Laboratories and research facilities: Storing liquid argon for suitable scientific and technical applications.
- Industrial gas distribution: Serving as bulk storage in liquid argon supply installations.
The final installation should include appropriately selected transfer piping, valves, pressure-control and relief devices, instrumentation, and vaporization equipment where required. These components must be designed for the intended service and applicable regulations.
How to Select the Right Vertical LAr Storage Tank
Choosing a suitable liquid argon tank requires more than matching the nominal capacity to daily consumption. Buyers should consider the following factors:
- Liquid argon demand: Estimate average and peak consumption, delivery frequency, and the required reserve capacity.
- Working pressure: Select the 0.8 MPa or 1.6 MPa option based on the system’s operating requirements and the approved design.
- Installation space: Check vessel dimensions, overall height, foundation requirements, transport access, and maintenance clearance.
- Downstream supply: Confirm the required gas flow, delivery pressure, and whether a vaporizer and pressure-regulating system are needed.
- Applicable standards: Specify the required design code, inspection, certification, and local regulatory requirements before ordering.

Vertical LAr Tank vs. Horizontal LAr Tank
A vertical tank is often considered when ground space is limited and sufficient installation height is available. A horizontal tank may be more appropriate where overhead clearance is restricted or the site layout favors a low-profile vessel. The final choice depends on capacity, engineering design, foundation conditions and operating requirements.
TECHNICAL FAQs
FAQ About Vertical LAr Storage Tanks
BluNet offers vertical liquid argon (LAr) cryogenic storage tanks with capacities ranging from 5 m³ to 100 m³. Available sizes include 5, 10, 15, 20, 30, 50, and 100 m³. The right capacity depends on your argon consumption, delivery schedule, and required storage reserve.
The available tank configurations have working pressures of 0.8 MPa or 1.6 MPa. Your choice should depend on the operating pressure required by your liquid argon storage and supply system, as well as the applicable design requirements.
The tank uses vacuum-perlite insulation to reduce heat transfer from the surrounding environment. This helps maintain cryogenic storage conditions and limit liquid argon evaporation. Actual evaporation rates depend on the tank design and the specified test conditions.
The supplied specifications list 06Cr19Ni10 stainless steel for the inner vessel and Q235-B carbon steel for the outer vessel. The final material specifications should be confirmed for the selected model and project requirements.
Start by considering your daily argon consumption, delivery frequency, required storage capacity, operating pressure, and available installation space. You should also assess downstream vaporization and gas supply requirements. Contact BluNet with your project details for help selecting a suitable configuration and requesting a quotation.
