Description: PSA Nitrogen Generator produces nitrogen gas from atmospheric air using molecular sieves separation technique. It uses carbon molecular sieves, which has ability to preferentially remove oxygen from air. The nitrogen generator consists of 2-beds filled with carbon molecular sieves. When compressed air is passed, nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process is called Pressure Swing Adsorption (PSA). MVS Engineering provides the nitrogen models in three models. The MS model is the simplest model that produces commercial grade nitrogen of 99% purity. However, if carbon molecular sieves quantity is increased, even 99.999% purity nitrogen can be produced from this model. This model is economical and is recommended for purity up to 99.9%. This model is commonly used for purging/inertizing applications. The DX model is used in metallurgical industries to provide oxygen free nitrogen gas for heat treatment furnaces. Here oxygen is less than 1-ppm and at the same time hydrogen is around 0.5 to 1% which is desirable as reducing constituent in, most of heat treatment applications. By adding palladium catalyst based deoxo purification module in Model-MS generator, it becomes DX-Model. This model also finds applications in chemical/electronic industries. The Copper-DX model is used in certain applications where one needs very pure gas free from oxygen as well as hydrogen, nitrogen purification module based on copper deoxo catalyst is added. By adding this copper catalyst module to MS-Model generator, it becomes Model-Copper- DX. This finds application in synthetic fiber, optical cables and electronic industries.
