PSA Nitrogen Generator
DAFD Series
Nitrogen Purity: 95-99.999%;
Gas Delivery: 10-4000Nm3/h;
Working Principle:
The nitrogen generator consists of two main adsorption towers. When clean compressed air enters the inlet of Tower A and flows towards the outlet through carbon molecular sieves, O2, CO2, and H2O are adsorbed by them, while the nitrogen product flows out from the outlet of the adsorption tower. After a period of time, the carbon molecular sieves in Tower A become saturated with adsorbed gases. At this point, Tower A automatically stops adsorption, and compressed air flows into Tower B for oxygen adsorption and nitrogen production, while Tower A's molecular sieves undergo regeneration.
The regeneration of the molecular sieves is achieved by rapidly reducing the adsorption tower to atmospheric pressure to remove the adsorbed O2, CO2, and H2O. The two towers alternate between adsorption and regeneration, completing the oxygen-nitrogen separation and continuously outputting nitrogen gas.
PSA Nitrogen Generator System Flow:
Generally speaking, a nitrogen production equipment based on pressure swing adsorption consists of several main components: air compressor, compressed air buffer tank, air purification system, air process tank, nitrogen generation unit, nitrogen process tank, electrical control system, and nitrogen storage tank.
It can also be used in conjunction with a liquid nitrogen system, which is commonly used to compensate for peak demand.
The Benefits of PSA Nitrogen Generator:
♦ Reliable Gas Supply
Stop relying on third-party suppliers for your nitrogen supply. Make your own with a nitrogen gas generator and experience 24/7 availability of gas. It is simple, reliable and durable.
♦ Cost-effective
Cost saving of 50% to 300%, creating your gas on-site ensures no expensive processing, refill and deliveries. It also removes the costly possibility of downtime due to a lack of gas.
♦ Safety
No safety or handling issues associated with bulky high pressure cylinders
Eliminates the dangers of cryogenic liquids
♦ Quality
PSA Nitrogen Generators can produce high-purity nitrogen, reaching up to 99.9999%, contingent on the model and configuration. This flexibility allows for purity level adjustments based on application requirements such as food packaging, laser cutting, or plastic molding.
♦ Plug-and-play
If you are looking for a large capacity nitrogen generation package, and footprint is critical, our frame-mounted N2 generators are quite simply best value for money.
Compression Technology:Based on a large amount of test data accumulated over many years of production, Denair adopts a dual compression structure of coconut pad compression and cylinder compression.
It avoids the shortcomings of short stroke, unstable force and inability to measure the amount of sinking when using coconut pad alone for compression.
It also avoids the shortcomings of small force area and loose sealing when using cylinder alone for compression.
Pneumatic Valve:Pneumatic valves are suitable for a variety of media including water, steam, and weakly corrosive gases and liquids. Their features include:
1. Integral structure of piston and valve core, double-acting form;
2. Good wear resistance and sealing performance;
3. Large flow area, low pressure loss, consistent performance in both forward and reverse flow;
4. Compact structure, easy installation and maintenance.
Electrical Control Components:1. PLCs are generally of Siemens brand, has high reliability and strong anti-interference ability;
2. HMIs are generally of Siemens brands, High resolution and 64,000 color shades help improve process visualization. The display's brightness is adjustable to 100% for flexibility;
3. Pneumatic components such as solenoid valves, pressure reducing filters, and pressure reducing valves are generally of Taiwan Airtac brand, with low power, lightweight appearance.
