Cryogenics is a field that developed rapidly over the last few years. The word Cryogenics represents both the theoretical discipline of low-temperature research and real technical devices that ensure cooling to temperatures near absolute zero and liquefaction of inert gases that found wide use across many industries. For example, liquefied Helium is used in cooling, magnetic resonance, astronautics, engineering to adjust steel structure or scientific research. PBS has built cryogenic devices with high precision and quality for more than 35 years.

In physics, cryogenics stands for reaching very low temperatures and studying such temperatures' effect on various materials and elements. It has been well known since the first successful helium liquefaction in 1908. The superfluidity and superconductivity of helium isotopes get a lot of attention nowadays. Cryogenic technology is necessary for efficient cooling of experimental workplaces and laboratories, i. e., the Large Hadron Collider in CERN, where PBS supplied turboexpanders for liquefaction of inert gases, compressors, and pumps. Unlike common cooling, cryogenics means extremely low temperatures. The scientific community set the temperature threshold between the designations cryogenics and cooling. This line starts at 93,15 K (-180 °C), the boiling point of so-called permanent gases such as nitrogen, hydrogen, oxygen, neon, and ends at absolute zero 0 K (-273,15 °C).

Currently, gas liquefiers' cryogenic technology is at the center of attention because of the rising interest in liquefied hydrogen (H2 liquefaction is -253 °C). Hydrogen is often called the fuel of the future because it holds the potential to replace fossil energy sources. PBS Velka Bites perceives the growing potential of hydrogen as a huge opportunity and develops larger cryogenic turboexpanders CTE 300 with a generator and cooling power up to 100 kW, primarily designed for hydrogen applications.

Liquefied hydrogen serves as fuel for starships, but besides that, it has a wide range of use in many industries, from transport to power generation. For example, in the United Kingdom, some buses run on hydrogen. Maritime freight transport should achieve a 95 % reduction of emissions according to plan thanks to hydrogen use. Australia is building a giant hydrogen power plant, and private companies have plans to construct a hydrogen fuel orbit station for interplanetary flights.

 Hydrogen is a chance to decarbonize the economy and a greener future, and innovative companies, including PBS, want to be part of it.
