Explore all the questions and answers that you may have when researching cryogenic and industrial gas storage, containers and transport options. These FAQ’s replicate the most common questions and answers that Lehigh Equipment Company typically receives from the majority of our prospects and customers.

Each cryogenic liquid has its own specific properties, but most cryogenic liquids can be placed into one of three groups:

  • Inert Gases: Inert gases do not react chemically to any great extent. They do not burn or support combustion. Examples of this group are nitrogen, helium, neon, argon and krypton.
  • Flammable Gases: Some cryogenic liquids produce a gas that can burn in air. The most common examples are hydrogen, methane and liquefied natural gas.
  • Oxygen: Many materials considered as non-combustible can burn in the presence of liquid oxygen. Organic materials can react explosively with liquid oxygen. The hazards and handling precautions of liquid oxygen must therefore be considered separately from other cryogenic liquids.

Liquid cryogens should only be stored in well-ventilated areas (do not store in a confined space).

Cryogenic liquids are stored in vacuum-jacketed containers. These cryogenic liquid containers are specifically designed to withstand extreme differences in temperature.

It is best to consult with an expert for help in determining the right vessel size and configuration. Here are a few important figures and information you will need.

  • Any current usage data, i.e. number of cylinders and/or Dewars used in a week or month
  • Your hourly, daily and monthly anticipated usage
  • Number of operating days per week
  • Site and seismic restrictions

  • Nature of soil and subsoil (stability, groundwater, …)
  • Ease of access.
  • Absence of electrical lines.
  • Absence of flammable liquid or gas lines.
  • Proximity to the point of use.
  • Accessibility to a supply vehicle using a single flexible hose with a maximum length of 12 feet.

When available, refurbished tanks are generally priced 15-20% less than new cryogenic storage tanks.
