Cryogenic microbulk tanks for safe and efficient gas storage and delivery

Cryogenic Microbulk Tanks for Efficient Gas Storage

Cryogenic microbulk tanks provide a compact, safe, and cost-effective solution for storing and supplying liquefied gases, including liquid nitrogen (LIN), liquid oxygen (LOX), liquid argon (LAR), and carbon dioxide (LCO₂). They are designed to bridge the gap between high-pressure cylinder bundles and large bulk storage systems, ensuring a continuous and high-purity gas supply.

Engineered with a reinforced base structure and high-efficiency vacuum insulation, microbulk tanks minimise heat ingress and reduce evaporation loss. They are typically suitable for facilities consuming between 500 m³ and 100,000 m³ of gas per month.

Types of Microbulk Tanks

Cryogenic microbulk tanks are compact, on-site liquid gas storage systems for argon (LAr), nitrogen (LN₂), oxygen (LOX), and carbon dioxide (CO₂). They provide a reliable, continuous supply for labs, medical facilities, welding shops, and small industrial operations.

By Gas Type

  • Liquid Argon: Welding, laser cutting. 1–5 m³
  • Liquid Nitrogen: Labs, medical, food. 0.5–3 m³
  • Liquid Oxygen: Medical, specialty industry. 0.5–3 m³
  • Liquid CO₂: Beverage, food, industrial. 0.5–2 m³

Key Features

  • Compact, space-saving design
  • Reliable continuous gas supply, reduces cylinder handling
  • Low boil-off for efficient storage
  • Skid-mounted or floor-standing installation
  • Supports lab, medical, and small industrial applications
