Nitrogen generators are dependable outlets for nitrogen. As the name implies, these machines are designed to generate, or create, nitrogen. Nitrogen is a clean, dry gas. The use of nitrogen generators eliminates the problems associated with handling gas cylinders. In addition, nitrogen generators cost less than gas cylinders. The gas is used for many applications, including:

Ø to fill tires in automobiles and aircraft, though not necessarily for regular consumer use

Ø to help preserve the freshness of bulk and packaged foods to place on the top of explosives

Ø to improve safety to aid in the production of electronic components.

Nitrogen generators are available with a multitude of different features and qualities. Some nitrogen generators available on the market, for example, require little or no maintenance after installation. Others include safety shut-off buttons and alarms. To eliminate the possibility of damage, the filter in nitrogen generators should be regularly changed.

The latest technology in nitrogen generators is the use of cryogenic air distillation, which is used to generate nitrogen. With this method, the air is compressed and then purified within the nitrogen generator. Later, it is cooled with a special cooling unit.Since the air runs through nitrogen generators, it runs through several filters. This process causes the air to become purified and to cool down even more. The oxygen and nitrogen are then separated within the oxygen liquid. The oxygen stays at the bottom, while the nitrogen remains on top. The entire process allows nitrogen generators to replenish themselves automatically with no manual input. This is achieved by way of the low temperature within the nitrogen generators, which mixes a small amount of liquid nitrogen into the nitrogen that is already produced.
