Our small nitrogen generators operate on the principle of Pressure Swing Adsorption (PSA), a cutting-edge gas separation technique. High-quality carbon molecular sieves are used as adsorbents. When compressed air, which has been purified and dried, enters the adsorption tower under pressure, the carbon molecular sieves selectively adsorb oxygen, carbon dioxide, water, and other impurities. Nitrogen, being less adsorbable, is left in the gas phase and is collected as the finished product. Through a PLC-controlled system, two adsorption towers work alternately - one for adsorption to produce nitrogen, while the other undergoes desorption to regenerate the adsorbent. This seamless process ensures a continuous and stable supply of high-purity nitrogen.
Unrivaled Features
Compact and Space - Saving Design
Designed with practicality in mind, our small nitrogen generators are compact in size, making them ideal for laboratories, small factories, and any space - constrained environment. Despite their small footprint, they pack a powerful punch in terms of performance.
Quick Start - Up and High Efficiency
In as little as 10 - 20 minutes, our generators can produce qualified nitrogen, getting your operations up and running in no time. The use of efficient molecular sieves and our unique PSA energy - saving technology results in lower energy consumption, making them not only fast but also cost - effective.
Customizable Purity Levels
We understand that different applications require different nitrogen purity levels. Whether you need nitrogen with a purity of 99% for general industrial use, 99.9% for food packaging to take advantage of nitrogen's inert properties and extend product shelf life, or even higher purity levels up to 99.999% for specialized applications like in the electronics or pharmaceutical industries, our small nitrogen generators can be customized to meet your exact needs.
Reliability and Low Maintenance
Built with high - quality components, our generators are known for their reliability. The use of market - proven commercial compressors, heat exchangers, and other key parts ensures long - term, trouble - free operation. With minimal maintenance requirements, you can focus on your core business without worrying about frequent equipment servicing.
Product Applications
Our small nitrogen generators find applications across a wide range of industries:
Laboratory Use
In laboratories, they are used for applications such as gas chromatography and mass spectrometry. The high - purity nitrogen provides a stable and inert environment for accurate experimental results. The generators' compact size and easy - to - use design make them perfect for laboratory benches, and the adjustable purity levels can meet the diverse needs of different experiments.
Food and Beverage Industry
For food packaging, nitrogen flushing is a popular technique to displace oxygen and extend the shelf life of products. Our small nitrogen generators can produce the required high - purity nitrogen, and with an additional food - grade filter, they ensure that the nitrogen used is safe for food contact. This not only helps food manufacturers reduce product waste but also maintain product quality and freshness.
Petrochemical and Chemical Industries
In petrochemical and chemical processes, nitrogen is used for purging, blanketing, and as an inert gas in reactions. Our generators can supply a continuous stream of nitrogen, ensuring smooth operations and enhanced safety in these industries. The ability to customize the nitrogen output according to the specific process requirements makes them a valuable asset.
Electronics Manufacturing
In the electronics industry, where even the slightest impurity can affect the performance of electronic components, high - purity nitrogen is essential. Our generators can provide nitrogen with extremely low levels of contaminants, making them suitable for applications such as soldering, semiconductor manufacturing, and electronic component storage.
