Our Liquid Nitrogen Storage Tanks, Your Solution

Imagine a world where the safe and efficient storage of liquid nitrogen is not a challenge, but a certainty. Our liquid nitrogen storage tanks are that certainty, meticulously designed with a double-walled, cylindrical structure. The inner vessel and piping, crafted from robust S30408 stainless steel, are encased in an outer shell made of durable Q245R alloy steel. Between these layers, we employ expanded perlite (pearl sand) alongside a specially treated adsorbent, creating a high-vacuum environment (0.5 to 6 Pa). Designed to handle high pressure, these tanks maintain a 2.0 MPa working pressure standard with dual tanks across four workshops. Conveniently, an external vaporizer facilitates easy filling and direct access to pressurized gas. Our tanks come in capacities up to 200 m³.

Whether you require long-term stationary storage or the mobility of transportable tanks, we provide the optimal solution. Stationary tanks, commonly found at production sites, usage points, or liquid supply centers, offer reliable storage. Transportable tanks – road tankers, trailers, and marine-based tankers – ensure efficient delivery from one point to another. Available in both vertical (L) and horizontal (W) configurations, our tanks adapt to diverse operational needs.

The Power of Technology:

Insulation: Cutting-edge powder insulation.

Pressure: High pressure functionality from 0.2-3.0 MPa.

Capacity: Options from 5 m³ up to 200 m³.

Semiconductor Manufacturing: Essential for processes such as packaging, gas filling, thermal oxidation and chemical vapor deposition.

Gas Industry: Supports the extraction of noble gases and treatment of critical tools.

Electronics: Serves as protective gas for integrated circuits, in lamp filling, and as an air/oxygen dispenser.

Food Processing: For rapid freezing, extended shelf life packaging, and efficient chilling.

Multipurpose: Used in industries from metallurgy to medicine, proving versatility.

Crafting Excellence:

Our production journey includes volume calculation and blueprint, preparation of materials, steel rolling, welding, assembly, insulation, vacuum creation, rigorous testing, rust treatment, and careful valve installation.

Key Advantages, Explained:

Unparalleled Insulation: The fusion of perlite sand, vacuum, and advanced filling techniques minimizes thermal loss and guarantees prolonged storage. Enhanced by a durable coating, ensuring lasting protection.

Safety Assured: The "combined safety system," featuring dual sets of safety valves, allows for safe maintenance while maintaining operational continuity.

Smart Management: Real-time stock and pressure monitoring through installed manometers, differential level gauges, and comparison tables keeps you in control.

Reliable Vacuum Monitoring: Regular checks with our integrated vacuum meters and valves to assure that the insulation layer vacuum is kept perfect, reducing any risk of failure.
