I. Overview:

Nitrogen is colorless, odorless, non-toxic, non-flammable, and non-explosive, making it extremely safe for use. Its molecular structure is highly stable, typically resistant to chemical reactions with other substances, and exhibits inert properties, widely used as a protective gas. This series of nitrogen generators utilizes the pressure swing adsorption principle, separating oxygen from nitrogen in the air through carbon molecular sieves to produce nitrogen. It boasts simple process flow, small footprint, low investment, easy operation, convenient maintenance, and more. The purity of the nitrogen produced can be adjusted according to actual needs, and the unit has good adaptability. The working principle is PSA nitrogen production, using high-performance CMS carbon molecular sieve AB twin towers for alternating continuous nitrogen production.PGN-40L High Purity Nitrogen Generator is compatible with various nitrogen blowers at home and abroad; widely used in laboratory analysis and testing departments in oil, chemical, coal, pharmaceutical, food, beverage, environmental protection, indoor detection, health, quarantine, electricity, public security, and universities.

The High Purity Nitrogen Generator is powered by an air compressor as the raw gas source, featuring high-quality double pumps, self-designed vibration and heat insulation measures, an automatic drainage system, a cooling system, a gas purification and filtration system, and an internal overpressure safety protection device. The storage cylinder is made of premium stainless steel material, and the control system has dual-level protection against overpressure and overcurrent. It includes stabilizing and throttling devices in the nitrogen gas circuit, ensuring the quality of the gas used. The operation is simple, safe, and reliable, guaranteeing the stability of continuous machine operation. The PGN-40L High Purity Nitrogen Generator is our flagship product, gaining increasing customer recognition. Key components in the gas circuit, such as solenoid valves and pressure regulators, use imported valve components to ensure stable operation under high pressure and high flow conditions, placing this product at the forefront of the market. This instrument is particularly suitable for large-volume gas supply. The machine has increased the compressor power and separation materials. Our company has mature technology and processes, easily handling continuous, high-load operations. The Nitrogen Generator has long become a substitute for steel cylinders due to its mature technology, ease of use, low cost of gas production, and high purity. It is increasingly being chosen by laboratories, leading to the complete elimination of expensive and dangerous high-pressure cylinders from the lab.

Section 2: Working Conditions and Environmental Requirements:

1. Requirements for compressed air sources:

Compressed Air Pressure: 0.6～0.8MPa       

Compressed Air Dew Point: <-10℃

Oil-free and water-free compressed air; Oil content in compressed air: <0.01 PPM

    Note: Regularly check if the automatic drain is functioning properly; otherwise, it will significantly affect the lifespan of the nitrogen generator.

2. Environmental Requirements:

Ambient Temperature: 5～40℃; Optimal operating temperature for the machine is 20-25℃

Relative Humidity: ≤80%

Power: 220V 50Hz

4. Power: 1150W

Weight: 140 kg

6. Dimensions: 700*600*1100

7. Nitrogen Output: 0-40L/min

Nitrogen Purity: 99-99.9%

3. Nitrogen Generator Operation Procedure

Power-on sequence:

Turn on the air pump switch and observe the pressure gauge after 2 minutes to ensure it reaches above 0.6 MPa.

2. Next, turn on the power switch, and the pressure in Tower A begins to rise. Towers A and B start alternating operations. As the nitrogen pressure gradually increases to 0.5 MPa, open the regulating valve of the nitrogen outlet pipeline, allowing the nitrogen pressure to be maintained at no less than 0.4 MPa and continuously discharged outward. The purity of the nitrogen will keep increasing until it reaches the required purity for use, then supply it to the user end.

3. Power off sequence: first close the nitrogen outlet, maintain the highest nitrogen pressure, then turn off the intermediate power and air pump switches.

4. The unit is equipped with an automatic start/stop pressure technology. Once the nitrogen pressure reaches 0.6MPA, the nitrogen machine automatically shuts off the power, during which the power button is non-functional. When the nitrogen pressure drops to 0.4MPA, the unit automatically starts up again, achieving energy saving and cost reduction.

IV. Quality Assurance Terms:

1. Nitrogen generators and equipment produced by our company come with a 12-month warranty, unless otherwise agreed upon in the contract. With normal usage as per this manual and regular maintenance checks, the equipment's lifespan should be between 8-10 years. Outside of the warranty period, our company will also handle equipment repairs until it is decommissioned. For repair services outside of the warranty period, we will only charge for parts.

2. Warranty Coverage: During the warranty period, the warranty for the equipment covers any failures or malfunctions due to inherent quality issues in certain parts of the equipment or instruments, or normal wear and tear, under the condition of normal operation by the user. These are all included in the free warranty service.

Customers requiring free warranty parts or equipment/instruments from our company are kindly requested to notify us promptly upon encountering any faults with the equipment or instruments. Please retain the faulty parts in their original condition. We will arrange for replacement as soon as our staff or a phone confirmation is made.
