Reliable LN2 Bulk Tank Solutions for Cryogenic Storage
BluNet manufactures high-performance liquid nitrogen bulk tank systems designed for the safe and efficient storage of liquid nitrogen (LN2). Our bulk liquid nitrogen storage tanks feature advanced vacuum insulation technology, low evaporation rates, and durable double-wall construction to ensure long-term cryogenic performance.
Available in capacities up to 20 m³, these LN2 bulk tanks are widely used in industrial manufacturing, laboratories, healthcare facilities, food processing plants, universities, and research institutions. In addition to liquid nitrogen, these tanks can also be configured for liquid oxygen (LOX), liquid argon (LAR), and liquid carbon dioxide (CO2) storage.
Designed for stationary installation, BluNet LN2 storage tanks provide dependable cryogenic storage while minimizing product loss, maintenance requirements, and operating costs.
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
- Fixed vertical installation for secure, stationary storage.
- High-density construction resists corrosion and chemical damage.
- Wide or narrow openings allow safe LN₂ transfer and pouring without spills.
- Available in multiple volumes (5 m³, 10 m³, 15 m³) and working pressures (0.8 MPa – 1.6 MPa).
- Supports low-pressure (1.5–4 bar) and high-pressure (up to 37 bar) LN₂ withdrawal.
- Optimized for energy efficiency with low static evaporation rates.
