Excellent Energy-saving Features Reduce Air Usage Cost
Advanced process flow directly reduces compressed air consumption
The energy-saving CMS nitrogen gas generator provided by RICH adopts unequal pressure equalization process (RL-VI flow, patent certificate no.364126).
This process improves desorption tower nitrogen purity and reduces CMS oxygen pre-adsorption in the desorption tower and increases CMS utilization ratio, i.e，increases carbon molecular sieve nitrogen production rate. RL-VI process not only improves nitrogen recycle rate and carbon molecular sieve utilization ratio, but also changes the history that no ppm class high purity nitrogen can be produced by PSA technology.
Nitrogen flow：5~12000 m3/h（20℃，101.325kPa）
Nitrogen purity： ≥97~99.9995%(Customizable)
Dew point： ≤-45℃(Customizable)
Nitrogen pressure：0.05~0.8Mpa (Customizable)
Nitrogen Generator with Cylinder Filling Supplier
RICH has been cooperating with world famous molecular sieve manufacturers for more than ten years. RICH can provide the most energy-saving products according to customers working condition. For some latest foreign components，RICH has obtained the sole purchase right in China.
Load adaptation is a new concept developed by RICH in its PSA system R&D experiences. It is the achievement of RICH technical engineers based on many years simulation experiments and repeating demonstrations. Under the circumstance of air consumption decrease, load adaptation realizes energy consumption reduction by prolonging adsorbing circulation period and realizes extra energy-saving in typical load range.
The most reliable air cleaning process ensures adsorbing efficiency and lifetime of molecular sieve
Carbon molecular sieve(CMS) is the core in PSA nitrogen generator. Oil poisoning is one of the main reasons for carbon molecular sieve invalidation. The adsorption of water reduces CMS’s oxygen adsorption capacity. Compressed air generated by oil lubricant air compressor contains oil and water, which must be removed before it enters oxygen/nitrogen separation assembly. Air cleaning assembly consists of pipeline filter, refrigerated dryer, precise filter, super precise filter, active carbon oil eliminator, automatic drain valve and ball valve.

A nitrogen generator is a device that extracts nitrogen gas from compressed air. It is commonly used in various industries to provide a continuous supply of high-purity nitrogen. There are three primary types of nitrogen generators:
Pressure Swing Adsorption (PSA) Nitrogen Generators:
Principle: PSA nitrogen generators use adsorbent materials, typically carbon molecular sieves (CMS), to separate nitrogen from oxygen and other gases in the air. The CMS preferentially adsorbs oxygen, allowing nitrogen to pass through.
Process: The system operates by cycling between two adsorption towers. While one tower is adsorbing oxygen, the other is regenerating by releasing the adsorbed gases.
Purity: PSA systems can produce nitrogen with purity levels ranging from 95% to 99.999%.
Membrane Nitrogen Generators:
Principle: Membrane nitrogen generators use semi-permeable membranes to separate nitrogen from other gases. The membranes allow oxygen, water vapor, and other gases to permeate through the membrane walls, while nitrogen is retained.
Process: Compressed air is passed through the membrane fibers, and the separation occurs based on the relative permeation rates of different gases.
Purity: Membrane systems typically produce nitrogen with purity levels up to 99.5%.
Cryogenic Nitrogen Generation
Principle: The principle of a cryogenic nitrogen generator is based on the fractional distillation of liquefied air. Air is composed mainly of nitrogen (78%), oxygen (21%), and argon (1%), along with trace amounts of other gases.
Purity: Cryogenic nitrogen generators are capable of producing nitrogen with extremely high purity levels, making them ideal for applications requiring ultra-pure nitrogen. The purity levels depend on the system design and operational parameters:
Typical Purity: 99.999% (5.0 grade) or higher.
Ultra-High Purity: Up to 99.9999% (6.0 grade) for specialized applications.
