Cryogenic Liquid Cylinders – Microbulk & Cryo Vessels

Maximize efficiency, enhance safety, and reduce the total cost of ownership with INOXAP’s Cryogenic Liquid Cylinders. Engineered to replace traditional, high-pressure compressed gas cylinders, these compact cryogenic dewars deliver up to 50x higher gas density in a similar footprint.
Whether your operations demand high-purity gases for healthcare, metal fabrication, or semiconductor manufacturing. Our state-of-the-art vacuum-insulated technology provides a seamless and continuous supply of liquid-phase gases with built-in ambient vapourisers.

What Makes Cryogenic Liquid Cylinders Better Than Compressed Gas Cylinders?

Traditional high-pressure cylinders have many operational inefficiencies and handling hazards that can become life-threatening. Here’s how our Portable Liquid Cylinders solve the most critical gas supply challenges:

  • Eliminates High-Pressure Dangers: Traditional cylinders hold gases at an extremely high pressure of 150-200 bar. This demands strict operational compliance and safety measures of high standards. These Cryogenic Liquid Cylinders operate at a safe low pressure of 10-35 bar, which reduces the risks by up to 87%.
  • Reduced Downtime: Compressed cylinders are heavy (60-80 kg), and constantly swapping them leads to production issues and labour-intensive handling. Cryogenic Liquid Cylinders increase the supply longevity and reduce the changing frequency from a daily to a monthly schedule.
  • No Wastage: Traditional cylinders are infamous for their high residual loss, leaving up to 25% of the gas trapped inside. Cryogenic Liquid Cylinders guarantee 98% gas utilization in comparison.
  • Floor Space Recovery: Valuable factory and hospital floor space is freed up by replacing the old tanks with a single compact Cryogenic Liquid Cylinders unit. These new vessels save up to 40% of the storage area.

Usable for 6 Types of Gases

Our new cryogenic liquid cylinders are equipped with ambient vaporisers that deliver seamless gas at the exact point of use.

  • Liquid Oxygen (LOX) [BP: −183°C]: Ideally used for metal cutting, welding, water treatment, glass manufacturing, aerospace and EAF steelmaking.
  • Liquid Nitrogen (LIN) [BP: −196°C]: The cylinders are optimised for cryogenic freezing, food preservation, pharmaceuticals, electronics cleanrooms and IVF storage.
  • Liquid Argon (LAR) [BP: −186°C]: Engineered for high-quality TIG/MIG welding, stainless steel production, semiconductor fabrication, and ladle refining.
  • Liquid Medical Oxygen (LMO) [BP: −183°C]: High-purity medical-grade supply for ICUs, operation theatres, hospital piped networks, and home healthcare.
  • Liquid Nitrous Oxide (LN₂O) [BP: −88°C]: Certified supply for medical anaesthesia, dental sedation, food industry whipping agents, and performance testing.
  • Liquid Methane (LCH₄): Made for rocket propulsion, LNG peak-shaving facilities, clean power generation, chemical feedstock synthesis and alternative fuel supply.

 

Key Industrial Applications

Cryogenic Liquid Cylinders play an important role across multiple industries. Our cylinders are used in:

Metal & Manufacturing: Used in laser cutting, TIG/MIG welding, EAF steelmaking and glass fabrication. In the steelmaking process, they are used for EAF/BOF furnaces, ladle refining, argon purging, high-volume consumption, and no complex manifolds.

Healthcare & Life Sciences: Our cylinders are NABH/JCI compliant, making them useful in medical-grade oxygen for ICUs and operating theatres, nitrous oxide for anesthesia and sedation, and cryogenic freezing for biological materials and IVF storage.

Electronics & Technology: Provides high-purity gases for semiconductor fabrication and environmental control in electronics cleanrooms.

Food & Beverage: Used in cryogenic freezing, MAP packaging, and to store nitrous oxide as a whipping agent.

Energy & Aerospace: LNG peak shaving facilities, clean power generation, rocket propulsion systems, and regasification operations.

Pharma and Biotech: Used for multiple applications like cryogenic preservation, bioreactor aeration, and sterile inerting. Purity is critical for GMP environments.

Electronics: Used for Ultra-pure N₂ blanketing for PCB soldering, semiconductor cleanrooms, and optical fibre production.

Water Treatment: They are used with dissolved O₂ for aerobic treatment and ozone generation feedstock. Our cylinders provide high purity at lower total cost.
