Lehigh Equipment Company has been a leading supplier of liquid cryogenic and industrial gas equipment since 1998. Lehigh is skilled in the use of Cryogenics, which uses cold temperatures to transition gases to a liquid state, known as cryogenic liquids.
Cryogenics Definition
Cryogenics is known as the science of studying and usage of extremely low temperatures, including refrigeration at below -180°C through gas liquefaction, so all cryogenic liquids are extremely cold.
What are Cryogenic Liquids?
Cryogenic liquids are liquified gases that are kept in their liquid state by cooling them below room temperature at a very cold temperature before increasing pressure liquifies them.
In general, there are 3 types of groups that most cryogenic liquids can be categorized into, each is described below, according to Oregon State
Oxygen
Reacts explosively with organic materials; supports combustion. This cryogen is Oxygen (O2).
Inert Gases
These gases do not react chemically to any great extent and do not burn or support combustion. These types of cryogens are Argon (Ar), Helium (He) and Nitrogen gas (N2).
Flammable Gases
Produce a gas that can burn in air when ignited. These cryogens are Hydrogen gas (H2), Methane (CH4) and Carbon Monoxide (CO).
What are Industrial Cryogenics Used For?
Industry application examples according to Wikipedia are, “Cryogenic gases are used in transportation and storage of large masses of frozen food. When very large quantities of food must be transported to regions like war zones, earthquake hit regions, etc., they must be stored for a long time, so cryogenic food freezing is used. Cryogenic food freezing is also helpful for large scale food processing industries.
Cryogenic cooling is used to cool the tool tip at the time of machining in the manufacturing process. It increases the tool life. Oxygen is used to perform several important functions in the steel manufacturing process.”

Cryogenic Liquid Storage Tanks
There are many options available to store cryogenic liquids from a variety of horizontal vessels and vertical bulk storage tanks. Lehigh offers new, used and reconditioned liquid cryogenic storage tanks, primarily for LOX, LIN, LAR and LCO2 service.
Transporting Cryogenic Liquid
Vessels that are used for transporting cryogenic liquids have to meet specifications and design for safe transport.
Lehigh Equipment Company offers used and rehabbed LOX, LION, LAR and liquid CO2 transport tanks. Lehigh also has liquid cryogenic ISO containers available. These cryogenic liquid transports are available for sale or lease, learn more about the specifications and options.
