THE SCIENCE OF EXTREME COLD

Cryogenics is the field of technology focused on producing, storing, and applying materials at ultra-low temperatures, typically below -160°C. At OPW CES, high-quality cryogenic solutions are foundational to clean energy, life sciences, and aerospace innovation.

WHAT IS CRYOGENIC TECHNOLOGY?

Derived from the Greek word “Kryos” (cold), cryogenics involves the liquefaction of gases for transportation, storage, and specialized industrial use. Key cryogenic gases include:

  • Liquid nitrogen (LN₂)
  • Liquid oxygen (LOX)
  • Liquid hydrogen (LH₂)
  • Liquid helium (LHe)
  • Liquid argon (LAr)

Each gas liquefies at a specific temperature—helium at -269°C, oxygen at -183°C—requiring precise engineering and handling.

HOW ARE CRYOGENIC TEMPERATURES ACHIEVED?

Cryogenic systems use several physical methods to reach ultra-cold states:

  1. Thermal Conduction – Transfers cold from cryogenic liquids to surrounding materials
  2. Evaporative Cooling – Uses energy loss from liquid-to-gas phase change
  3. Joule-Thompson Expansion – Cools gases through rapid pressure drops
  4. Adiabatic Demagnetization – Cools using energy-absorbing paramagnetic salts

These techniques enable applications such as superconductivity, liquefied natural gas (LNG) storage, and hydrogen fueling infrastructure.

THE HISTORY OF CRYOGENIC TECHNOLOGY

MORE AND MORE LIQUID GASES EMERGE

By the 19th century, cryogenics became more widely known, as by then more and more gases could be successfully liquefied.

It all began back in 1877 when Callietet and Pictet succeeded in liquefying oxygen. Experiments were in full swing around that time, and soon liquid versions of other gases appeared. For example, in 1884, hydrogen was the first gas to be converted to mist. In 1862, Sir James Dewar developed a vacuum-insulated vessel to store cryogenic liquids, making it easier to work with liquefied gas. In the following years, experts succeeded in liquefying an increasing number of gases, including the last in line, helium. The liquid form of this gas was first used in 1908.

CRYOGENIC TECHNIQUES ACROSS A VARIETY OF INDUSTRIES

Meanwhile, more and more industries discovered the usefulness of cryogenic technology. In 1961, for example, cryosurgery was first practiced in the United States. Scientists found that slow cooling could destroy unhealthy human tissue. In the United States, liquid nitrogen was used for this purpose, and a few years later, physicians in South Africa also used the method there. In South Africa, however, nitrous oxide was used instead of liquid nitrogen.

The aerospace industry also introduced cryogenic technology in the 20th century. In 1961, the American Atlas-Centaur rocket used liquid hydrogen and liquid nitrogen for the first time in the space program. This event is considered a significant milestone in cryogenics and immediately led to large-scale liquid hydrogen production for similar projects.

The medical and aerospace industries are just examples of sectors where cryogenic technology has been in use for a long time already. Cryogenics has also, for a long time, taken a prominent role in scientific research, the marine industry, and the mass production of liquefied gases in air separation units.
