Ten common questions about nitrogen generators

1.What purity of nitrogen gas can a nitrogen generator produce?

A nitrogen generator can produce nitrogen gas of various purities, ranging from standard industrial-grade nitrogen (typically 95% to 99% purity) to high-purity nitrogen (usually exceeding 99.9%), and even ultra-high purity nitrogen (typically exceeding 99.999%). The choice of purity depends on specific application requirements.

2.What is the working principle of a nitrogen generator?

They provide a reliable and on-demand source of nitrogen for various processes, including inerting, purging, and blanketing. These applications help prevent oxidation, enhance safety, and maintain product quality.
• In the medical field, nitrogen generators are essential for anesthesia and gas delivery systems. They supply medical-grade nitrogen, which is critical for respiratory support, patient care, and surgical procedures. The precise control and continuous availability of nitrogen are paramount in these critical healthcare applications.

By providing a steady and readily available source of nitrogen, these systems contribute to the success and advancement of various sectors.

3.What inputs does a nitrogen generator require, and how does it operate?

A nitrogen generator typically requires air as the input source. When operating the nitrogen generator, air is compressed using an air compressor and then processed through the adsorber with molecular sieves or the membrane separator within the nitrogen generator. Finally, pure nitrogen is obtained as the output. Some nitrogen generators may also require an electrical power supply.

4.How is a nitrogen generator different from nitrogen supply in gas cylinders?

• The primary distinction between a nitrogen generator and nitrogen supply in gas cylinders lies in their supply modes. A nitrogen generator operates by extracting nitrogen from the surrounding air continuously, ensuring a constant and uninterrupted nitrogen supply. This eliminates the need for frequent cylinder replacements and allows for a reliable and steady nitrogen flow.
• On the other hand, nitrogen supply in gas cylinders involves the use of pre-filled cylinders containing compressed nitrogen. The supply quantity is limited by the capacity of the cylinders, and once the nitrogen is depleted, the empty cylinders must be replaced with full ones. This periodic cylinder replacement process can cause interruptions in nitrogen supply and may require additional logistics to manage the inventory of cylinders.
• The advantage of a nitrogen generator is its ability to provide a continuous supply of nitrogen without the hassle of cylinder replacements. It offers greater flexibility, convenience, and cost-effectiveness, especially for applications with high nitrogen consumption. However, the choice between a nitrogen generator and cylinder supply ultimately depends on factors such as nitrogen demand, cost considerations, and specific application requirements.

5.What should be considered for the maintenance of a nitrogen generator?

The maintenance of a nitrogen generator typically involves regular cleaning and replacement of the adsorber with molecular sieves or membrane separator, inspection and maintenance of the compressed air system, monitoring nitrogen generation performance, etc. Specific maintenance requirements should be referred to the user manual or guidance provided by the manufacturer of the nitrogen generator.

6.Which industries are nitrogen generators suitable for?

Nitrogen generators are widely used in various industries, including industrial, medical, food and beverage, and laboratory applications. They are commonly used in industries such as chemicals, electronics, and metal processing. In the medical field, they are used for anesthesia and gas delivery. In the food and beverage industry, they are used for packaging and preservation. In laboratories, they are used for atmospheric control and protection of equipment.

7.What is the noise level of a nitrogen generator during operation?

8.How long does it take for a nitrogen generator to start producing nitrogen gas?

The startup time of a nitrogen generator depends on the model and specifications. In general, nitrogen generators have short startup times, typically ranging from a few minutes to several tens of minutes. Larger capacity or higher purity requirement nitrogen generators may require longer startup times.

9.Can a nitrogen generator simultaneously produce nitrogen gas and oxygen gas?

The design purpose of a nitrogen generator is to separate oxygen and nitrogen to produce high-purity nitrogen gas. Therefore, in most cases, a nitrogen generator does not simultaneously produce nitrogen gas and oxygen gas. If simultaneous production of nitrogen and oxygen is required, additional equipment or techniques need to be used for further processing.

10.What is the energy consumption of a nitrogen generator?

The energy consumption of a nitrogen generator varies depending on the model, specifications, and operating conditions. Generally, nitrogen generators have relatively low energy consumption, especially when compared to traditional nitrogen supply in gas cylinders. Nitrogen generators are typically adjusted based on the actual nitrogen demand to improve energy efficiency and minimize energy consumption.
