What is cryogenic equipment used for?


Cryogenic equipment is used when you need to operate at extremely low temperatures – the acceptable division between simple refrigeration and cryogenics is -180 degrees Celsius. Typical equipment used in cryogenic applications includes containers, pressure vessels, cold traps, purifiers and piping.


Among the most commonly used cryogenic equipment is a specialised container known as a Dewar flask. (insert link to Divlac Dewar Flask page) Named after its inventor, Scot ‘Sir James Dewar’. This famous piece of cryogenic equipment comprises of a holding chamber within near vacuum, and the Dewar flask prevents the transmission of heat from its contents through the processes of conduction and convection. Dewar flasks also reduce the transmission of heat through the process of radiation, by using selected reflective coatings for various surfaces within the flask. In cryogenic applications, Dewar flasks are typically used as holding tanks for the selected cryogenic liquid.


How does cryogenic equipment work?


Proper insulation is often key to the effectiveness of cryogenic components, as it ensures that temperature levels are maintained within the equipment. Similarly, insulation protects cryogenic equipment users from dangerous temperatures and materials during handling. Of the liquids regularly used in cryogenic operations, nitrogen and helium are the most common; liquid helium in particular allows for extremely low temperatures. Also important to most cryogenic equipment, especially valves, gages and piping systems, is the pressure rating of the unit; the majority of cryogenic systems have specific pressure requirements in order to retain fixed temperatures.
