Cryogenic is the science of very low temperatures with range b/w -173 ºC and absolute zero (-273 ºC) . Generally cryogenic deals with temperatures below -100 ºC. The subtances having normal boiling point arround -100 ºC refered as cryogens. Some of the example of cryogenic fluids are Helium, Oxygen, Nitrogen, Methane, etc.

Cryogenic applies to many industries from LNG (liquefied natural gas) to Semiconductor processes to Food Processing/Storage, as well as Biotechnology environment.
