Reliable LN2 Bulk Tank Solutions for Cryogenic Storage
BluNet supplies liquid nitrogen bulk tanks for stationary cryogenic storage in industrial plants, laboratories, healthcare facilities, food processing operations, and research institutions. Designed for liquid nitrogen (LN₂), these vacuum-insulated storage systems combine a pressure-rated inner vessel with a protective outer shell to minimize heat transfer and reduce liquid evaporation.
Our bulk liquid nitrogen storage tanks are available in multiple capacities and working-pressure configurations. Standard models include 5 m³, 10 m³, and 15 m³ tanks, with other capacities subject to engineering confirmation. Each system can be configured according to site conditions, liquid nitrogen consumption, operating pressure, and downstream gas supply requirements.
BluNet provides cryogenic storage equipment for customers seeking reliable liquid nitrogen storage, handling, and supply solutions.

Tank Design and Materials
Each tank features a dual-vessel design with:
- An inner tank made of stainless steel 304L (X5 CrNi 18-10) with EN13458 certification for pressure containment.
- An outer tank constructed from carbon steel(Q235-B), providing structural integrity.
- A vacuum-insulated perlite layer to minimize thermal transfer and reduce LN₂ evaporation.
This vertical fixed mounting design ensures stability, eliminates the need for mobile supports, and maintains a compact footprint in labs or production facilities.
Key Features
- Stationary vertical installation: Designed for fixed cryogenic storage at industrial and institutional sites.
- Vacuum insulation: Helps reduce heat ingress and liquid nitrogen losses during storage.
- Multiple capacity options: Standard specifications include 5 m³, 10 m³, and 15 m³ models.
- Different working pressures: Available configurations include 0.8 MPa and 1.6 MPa, subject to the selected model.
- Integrated safety equipment: Pressure-relief devices, valves, instrumentation, and piping are specified for the intended service.
- Configurable liquid supply: Outlet arrangements and optional pressure-building or vaporizer systems can be evaluated according to project requirements.
- Project-specific engineering: Materials, connections, accessories, and applicable design standards are confirmed for the intended operating conditions.
Actual performance depends on tank capacity, design pressure, insulation condition, operating conditions, and the selected equipment configuration.

LN2 Bulk Tank Applications
Industrial Manufacturing and Metal Processing
Liquid nitrogen bulk tanks provide a supply source for cryogenic cooling, metal treatment, precision manufacturing, and other industrial processes requiring low-temperature nitrogen.
Medical and Healthcare Facilities
Healthcare and biotechnology facilities may use liquid nitrogen for approved cryogenic applications, including biological sample handling and specialized laboratory processes. Storage and distribution arrangements must meet the requirements of the intended application.
Food Processing and Freezing
Bulk LN2 storage systems can supply liquid nitrogen for rapid freezing, temperature control, and food-processing operations. Tank capacity should be selected according to consumption rates, delivery schedules, and peak production demand.
Research Laboratories and Universities
Research institutions use liquid nitrogen in material testing, low-temperature experiments, cryogenic research, and laboratory equipment applications.
Cryogenic Equipment and Gas Supply Systems
A liquid nitrogen tank can form part of a larger supply system serving process equipment and gas distribution networks. Depending on the required output, the installation may incorporate vaporizers, pressure-control equipment, pipelines, and monitoring instruments.
Materials, Standards and Customization
The appropriate material specification and manufacturing standard depend on the tank design, operating pressure, intended service, and destination market. The supplied design information identifies stainless steel for the inner vessel and carbon steel for the outer shell. Exact material grades and certification must be confirmed in the approved documentation for the selected model.
BluNet can evaluate project-specific requirements such as:
- Tank capacity and working pressure
- Vessel materials and applicable design standards
- Liquid inlet and outlet connections
- Pressure-building and liquid-transfer arrangements
- Vaporizer integration and downstream gas supply requirements
- Instrumentation, valves, and safety accessories
- Installation conditions and destination-country requirements
Other cryogenic liquids, including liquid oxygen and liquid argon, require appropriately engineered configurations. Compatibility with a different medium must not be assumed solely because the vessel is designed for liquid nitrogen. Liquid carbon dioxide also requires a suitable design for its distinct operating conditions.
