LN2 cryogenic storage tanks

LN2 Storage Tanks

LN2 Tanks are vertical or horizontal double-layer vacuum-insulated cryogenic storage tanks for storing liquid oxygen, nitrogen, argon, carbon dioxide, and other media.
The primary function is to fill and keep the low-temperature liquid.
LN2 storage tanks can effectively and safely store and handle liquid nitrogen for various industrial, medical, and scientific applications.
Storage Capacity and Types:

  • Various Capacities: Available in a range of sizes from small dewars (a few liters) to large bulk storage tanks (thousands of liters).
  • Static and Mobile: Includes both static storage tanks for stationary use and mobile tanks for transportation and distribution.

Liquid nitrogen—LN2—is nitrogen in a liquid state at low temperatures. Liquid nitrogen has a boiling point of about −195.8 °C (−320 °F; 77 K). It is produced industrially by fractional distillation of liquid air.

DSW tanks are engineered to achieve high levels of standardization, optimizing production costs and minimizing delivery times for efficient and expedited service.
Our standard tank offerings meet over 95% of customer requirements, with additional customization available upon request.

Key Features:

  • Wide Range of Capacities: Available in sizes from 1,500 to 264,000 US gallons (6,000 to 1 million liters).
  • Pressure Ratings: Designed for maximum allowable working pressures between 175 psig (12 bar) and 37 bar.
  • Configurations: Offered in both horizontal and vertical orientations to suit various installation requirements.
  • Thermal Insulation:
    • Vacuum Insulation: Most LN2 tanks use a vacuum insulation technique where a vacuum is created between the inner and outer tank walls to minimize heat transfer and maintain the extremely low temperature of liquid nitrogen (-196°C or -320°F).
    • Multilayer Insulation: Some tanks also use multilayer insulation (MLI) composed of reflective layers to further reduce heat ingress.
  • Advanced Insulation: Equipped with Perlite or Composite Super Insulation systems, ensuring superior thermal performance, extended hold times, and reduced life-cycle costs. The lightweight design also lowers operational and installation expenses.
  • Construction Materials: Typically made of stainless steel or aluminum, materials that offer strength and resistance to extreme cold temperatures.
  • Double-Jacketed Construction:
    • Inner Vessel: Made of stainless steel for durability and purity.
    • Outer Shell: Constructed from carbon steel with an integrated support and lifting system, facilitating easier transport and installation.
  • Corrosion Resistance: Features a durable coating that maximizes corrosion resistance and meets environmental compliance standards.

These features ensure that DSW’s LN2 bulk storage tanks provide reliable and efficient storage solutions for a variety of industrial applications.
