High Purity Nitrogen Output (99.999%)
The ZHN-05 nitrogen generator produces nitrogen with a purity of 99.999%, ensuring that it meets the stringent requirements of industries like electronics, pharmaceuticals, food packaging, and laser cutting.
Controllable Nitrogen Flow Rate
The generator is equipped with a flow meter that allows precise control of the nitrogen output flow rate. Lowering the flow rate appropriately increases the nitrogen concentration, ensuring that it matches specific application needs.
Programmable Time Relay for Efficient Operation
The programmable time relay allows users to adjust the working order and pressure relief time of the dual towers (A and B). The unit typically comes pre-set with the optimal time parameters, minimizing the need for user adjustments and ensuring efficient operation.
Pressure Gauges for Monitoring
Air pressure gauge: Monitors the pressure of the air entering the nitrogen generator. Under normal operation, the air pressure should be between 0.6-0.8 MPA.
Nitrogen pressure gauge: Shows real-time nitrogen pressure in the storage tank.
Tower pressure gauges (A and B): Monitors the pressure values in both carbon molecular sieve tanks (Tower A and Tower B). Usually, one tower is in working mode while the other is in a pressure relief or low-pressure state.
Advanced PSA Technology
The Pressure Swing Adsorption (PSA) technology used in the ZHN-05 generator ensures a highly efficient separation of nitrogen from other gases in the air, producing a consistent and pure nitrogen output.
Compact Design for Easy Integration
The ZHN-05 has a compact design (1300x700x650 mm), making it easy to integrate into a variety of industrial setups without taking up too much space.
The ZHN-05 nitrogen gas generator is ideal for industries requiring high-purity nitrogen for various processes, including:
Laser Cutting and Welding
Provides high-quality nitrogen to prevent oxidation during laser cutting and welding of metals, ensuring clean, precise cuts and welds.
Electronics Manufacturing
Used in the electronics industry to create an inert atmosphere for sensitive components, preventing contamination and damage during manufacturing.
Food Packaging
Used in food packaging to extend shelf life by creating a nitrogen-rich environment that helps preserve freshness and prevent spoilage.
Pharmaceutical Industry
Ensures a sterile and inert environment for pharmaceutical manufacturing, packaging, and storage.
Chemical and Petrochemical Industries
Provides an inert atmosphere for processes that require nitrogen for blanketing, preventing oxidation and other chemical reactions.
Air Inlet Preparation
Use a 16mm air pipe for the air inlet. It is crucial that the air source is dehydrated and deoiled before being connected to the nitrogen generator to prevent damage and ensure optimal performance.
Nitrogen Outlet Connection
The nitrogen outlet uses a 12mm air pipe. The qualified nitrogen can be directly supplied to the end equipment or storage system.
Pressure Gauge Monitoring
Regularly check the air pressure gauge, nitrogen pressure gauge, and tower pressure gauges to ensure proper functioning and maintain efficiency.
Routine Maintenance
Ensure regular cleaning and servicing of the PSA system to maintain high performance. Periodically inspect the components for wear and tear, and replace any filters or parts as needed to maintain the nitrogen output purity.
Connect Compressed Air:
Ensure the compressed air is connected to the nitrogen machine correctly.
Check Air Pressure:
The air pressure should be maintained between 0.6-0.8 MPA before starting the system.
Power On:
Turn on the power switch of the nitrogen generator to begin operation.
Operation of AB Towers:
The AB towers (carbon molecular sieve towers) will start to operate alternately. This is part of the PSA (Pressure Swing Adsorption) process that separates nitrogen from other gases.
Nitrogen Pressure Rise:
The nitrogen pressure will rise gradually to the specified maximum pressure. This process can take a few minutes depending on the specific generator model.
Open Nitrogen Outlet:
After 40-50 minutes of operation, open the nitrogen outlet and begin discharging any unqualified ammonia or impurities. The nitrogen generator will begin supplying qualified nitrogen to the connected equipment.
Shutdown Procedure:
Close all nitrogen outlet valves.
Turn off the power switch of the nitrogen generator.
This ensures the system safely shuts down and is ready for the next use.
Pressure Maintenance:
When the generator is powered off, the nitrogen pressure should maintain its highest value. Upon the next startup, the purity of the nitrogen will rise more quickly.
Dehydrated and Deoiled Air:
The air source must be dehydrated and deoiled before being connected to the nitrogen generator. This is crucial to avoid damage to the generator and maintain its efficiency.
Avoid Overpressure and Overtemperature:
The nitrogen generator should never be used under conditions of overpressure or overtemperature, as this may cause system failure or damage to components.
Close Nitrogen Outlet Valve:
Ensure the nitrogen outlet valve is fully closed to stop the flow of nitrogen.
Turn Off Power:
Switch off the nitrogen generator's power to prevent unnecessary power consumption and ensure safety.
Turn Off Dryer Power:
If the system includes a dryer, ensure the power to the dryer is also turned off to avoid damage.
Turn Off Air Compressor Power:
The air compressor that supplies the air to the nitrogen generator should be turned off after operation.
Close Air Inlet Valve:
Finally, close the air inlet valve to prevent any air from entering the nitrogen generator when it is not in use.
Disconnect Power Supply and Drain Pressure:
Before performing any maintenance, disconnect the nitrogen generator from the power supply and release any internal pressure. This ensures safety during cleaning and maintenance.
Clean the Outer Shell:
Use appropriate cleaning agents and tools to clean the outer shell of the nitrogen generator. Be cautious not to allow water or cleaning agents to enter the internal components, as this could cause damage to the system.
Replace or Clean Filters:
Regularly check and replace the internal filters to maintain the generator’s efficiency. A clean filter ensures optimal nitrogen purity and prevents contamination in the output.
Dry the Generator:
After cleaning, make sure the nitrogen generator is completely dry before powering it back on. Moisture can cause damage or impair the system's performance.
