In the metal heat treatment processing industry, we can say that nitrogen is main role. Nitrogen is the original gas material in the metal heat treatment, like: bright quenching, bright, annealing, nitriding atmosphere, nitrocarburizing etc. Welding and powder metallurgy burning also use nitrogen as protection gas, When they are working, so nitrogen has a big significance to the metal processing industry.

Due to the requirement in the Metal heat treatment processing industry, GASPU provide the PD5N model's nitrogen generator to produce the high quality nitrogen metal processing industry need. Of course all of our nitrogen generators can be designed by our clients' requirement. This is our key feature.

Brief Principles

Each gas has a characteristic adsorption rate when adsorbed by Carbon Molecular Sieve (CMS). CMS has a large surface area containing a volume of micro pores and passageways. Oxygen has a higher adsorption rate than nitrogen. When compressed air enters CMS, nitrogen molecules are able to pass through this large surface. And oxygen molecules are adsorbed to the surface area.
As the CMS is saturated with oxygen, it should be depressurized to regenerate for the next cycle. We use two towers filled with CMS to produce a continuous stream of nitrogen.
During depressurization, the nitrogen of lower purity than required is transferred to another tower called pressure equalization. Pressure equalization donates to higher efficiency and less energy consumption.
Know-how in the definite time and ways to equalize the pressure is the key to the best results.
