Liquid Nitrogen Bulk Tanks

BluNet is a professional liquid nitrogen bulk tank manufacturer and exporter in China, supplying vacuum-insulated LN₂ cryogenic storage tanks for industrial gas suppliers, EPC projects, laboratories, hospitals, and manufacturing facilities. Our tanks are designed for safe, long-term storage of liquid nitrogen at −196°C with low evaporation loss and stable performance.

ASME, PED & EN-Compliant LN₂ Tank Design

BluNet liquid nitrogen bulk tanks are designed and manufactured in compliance with ASME Section VIII, European PED, and applicable EN standards, depending on project and destination requirements.

Each tank features a vacuum-insulated, double-wall structure with a cryogenic-grade stainless steel inner vessel and a carbon steel outer shell with corrosion-resistant coating, suitable for outdoor installation.

Vacuum Insulation & Thermal Efficiency

The evacuated annular space is filled with high-efficiency insulation material to minimize heat ingress and nitrogen boil-off, ensuring extended holding time and reduced operating costs.

Vertical & Horizontal LN₂ Bulk Tanks

BluNet supplies vertical and horizontal liquid nitrogen bulk tanks with customizable capacities, design pressures, and valve configurations to match site conditions and industrial gas systems.
