I. Overview:

Nitrogen is colorless, odorless, non-toxic, non-flammable, and non-explosive, making it very safe for use. Its molecular structure is highly stable and typically does not react chemically with other substances, exhibiting inertness and being widely used as a protective gas. This series of nitrogen generators utilizes pressure swing adsorption technology to separate oxygen from nitrogen in the air through carbon molecular sieves, producing nitrogen. It boasts simple process flow, small footprint, low investment, easy operation, convenient maintenance, and more. The purity of the produced nitrogen 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 continuous nitrogen production in an alternating work mode.The PGN-50L high-purity nitrogen generator is compatible with various nitrogen blowers worldwide; widely used in laboratory analysis and testing departments across industries such as oil, chemicals, coal, pharmaceuticals, food, beverages, environmental protection, indoor testing, sanitation, quarantine, electricity, public security, and universities.

The High Purity Nitrogen Generator is powered by an air compressor as the raw gas source, featuring superior double pumps, independently designed vibration and heat insulation measures, automatic drainage system, cooling system, gas purification and filtration system, and built-in overpressure safety protection devices. The gas storage tank is made of premium stainless steel material. The control system has dual-stage protection against overpressure and overcurrent. Stabilization and throttling devices are connected in the nitrogen gas circuit, ensuring the quality of the gas used. The operation is simple, and the equipment is safe and reliable, guaranteeing the stability of continuous operation. The PGN-50L High Purity Nitrogen Generator is our flagship product, increasingly recognized by customers. The main components in the gas circuit, such as solenoid valves and pressure regulators, use imported valves to ensure stable operation under high pressure and high flow conditions, placing this product at a leading position in the market. This instrument is particularly suitable for large-volume gas supply. The machine has increased the compressor power and separation material, and our company has mature technology and processes to handle continuous, high-load operations with ease. The Nitrogen Generator has long become a substitute for cylinders due to its mature technology, safety, ease of use, low cost of gas production, and high purity, making it increasingly popular in laboratories and completely replacing the expensive and dangerous high-pressure cylinders in the lab.

Section II: Working Conditions and Environmental Use:

1. Requirements for compressed air sources:

Compressed Air Pressure: 0.6～0.8MPa       

Compressed Air Dew Point: <-10℃

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

    Note: Regularly check that the automatic drain is functioning properly; otherwise, it will severely affect the nitrogen generator's lifespan.

2. Environmental Requirements:

Ambient Temperature: 5-50℃; Optimal operating temperature for the machine is 20-25℃

2. Relative Humidity: ≤80%

Power: 220V 50Hz

4. Power: 1150W

5. Weight: 150KG

6. Dimensions: 700*600*1100

Nitrogen Output: 0-50L/min

8. Nitrogen Purity: 99-99.9%

Section 3: Nitrogen Generator Operating Procedure

Power-on sequence:

Turn on the air pump switch, and after 2 minutes of operation, check the air pressure gauge to ensure it reaches above 0.6mpa.

2. Next, turn on the power switch. The pressure in Tower A begins to rise, and Towers A and B start alternating. As the nitrogen pressure gradually increases to 0.5 MPa, open the regulating valve of the nitrogen gas outlet pipeline to maintain a continuous discharge at a pressure not below 0.4 MPa. The purity of the nitrogen will gradually increase and reach the required purity for use.

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

4. Equipped with automatic start/stop pressure technology, the nitrogen generator automatically shuts off power when the nitrogen pressure reaches 0.6MPA. During this period, the power button is non-functional. Once the nitrogen pressure drops to 0.4MPA, the unit automatically resumes operation, promoting energy conservation 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 use as per this manual and regular proper maintenance and inspections, the equipment's lifespan should be between 8-10 years. Outside of the warranty period, our company will also handle equipment repairs until the equipment is scrapped. For repair services outside the warranty period, our company will only charge for parts.

2. Warranty Coverage: During the warranty period, the warranty for 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.

For parts or equipment requiring free warranty from our company, please notify us promptly upon any malfunction of the device or instrument, and retain the faulty part as received. We will arrange for a replacement upon confirmation via our representative or phone call.
