Liquid Nitrogen Generator
Overview
Liquid nitrogen generators produce liquid nitrogen (LN2) through various methods, including cryogenic distillation, pressure swing adsorption (PSA), and membrane separation.
Types
Cryogenic Distillation Generators
Pressure Swing Adsorption (PSA) Generators
Membrane Separation Generators
Cryogenic Expansion Generators
Stirling Cryogenic Generators
Principle
Air is compressed and filtered.
Air is cooled to extremely low temperatures.
Nitrogen is separated and liquefied.
LN2 is stored in a Dewar flask or tank.
Applications
Cryopreservation and cryostorage
Medical research and healthcare
Food freezing and packaging
Material testing and analysis
Aerospace and defense
Electronics manufacturing
Laser cutting and welding
