Liquid Nitrogen Storage Tanks: Reliable Solutions for Diverse Applications

Our liquid nitrogen storage tanks are engineered for optimal performance and safety. Constructed with a double-walled, cylindrical design, these tanks feature an inner vessel and piping made from durable S30408 stainless steel, while the outer shell utilizes robust Q245R alloy steel. The space between the layers is filled with expanded perlite (pearl sand) and a specially treated adsorbent, creating a high-vacuum environment (0.5 to 6 Pa). These tanks, with capacities up to 200 m³, operate at high pressures (with a standard 2.0 MPa working pressure across four workshops’ dual tanks). An external vaporizer allows for convenient filling and direct pressurized gas supply.

Liquid Nitrogen Storage Tanks: Reliable Solutions for Diverse Applications

Depending on the application, tanks are available in stationary and transportable models. Stationary tanks, typically installed at production facilities, points of use, or cryogenic liquid supply stations, are ideal for long-term storage. Transportable tanks, including road tankers, trailers, and ship tankers, facilitate the delivery of cryogenic liquids between production sites and user locations. Tanks are available in both vertical (L) and horizontal (W) orientations to suit diverse installation needs.

Key Features:

Insulation: Powder insulation for minimal heat transfer.
Operating Pressure: 0.2-3.0 MPa.
Capacity Range: 5 m³ to 200 m³.
Design Temperatures: -196 °C to -50 °C.
Filling Percentage: 95%.

Advantages:

Vacuum powder insulation, a compact structure, low daily evaporation rates, a small footprint, centralized control systems, high reliability, and user-friendly operation and maintenance are just some of the key features that set our tanks apart.
