I. Core Advantages of Minnuo PSA Oxygen Generator

Minnuo Group’s PSA oxygen generator takes pressure swing adsorption technology as the core, relying on advanced molecular sieve screening and system optimization design, focusing on the four cores of “high efficiency, stability, energy saving, and safety”. It adapts to the gas demand of medical, industrial, environmental protection and other scenarios, breaks the limitations of traditional oxygen production modes, and realizes the convenience and low cost of on-site oxygen production.

Controllable High Purity, Adapting to Full-Scenario Needs

Minnuo PSA oxygen generator adopts high-quality zeolite molecular sieves (such as Zeolite 13X or LiX). Through precise control of adsorption and regeneration cycles, the oxygen purity can be flexibly adjusted. Medical-grade products stably output 93%±3% purity oxygen, which fully meets China’s YY/T 0298 and European Pharmacopoeia standards, and is widely used in medical scenarios such as ICUs, operating rooms, and respiratory treatment centers. Industrial-grade products can achieve 95%~99.5% purity customization, adapting to high-purity oxygen source needs such as glass smelting, ozone reaction, and metal cutting. The purity fluctuation is controlled within a very small range to ensure stable and reliable gas quality.

High Efficiency and Energy Saving, Significantly Reducing Operating Costs

Compared with traditional cryogenic air separation and electrolytic water oxygen production methods, Minnuo PSA oxygen generator does not require low-temperature liquefaction or high-power consumption reactions. Its energy consumption is only 1/3 of that of cryogenic method, and the power consumption is controlled at 0.4~0.6kWh/Nm³ oxygen, which greatly reduces the long-term operating costs of enterprises. At the same time, the system adopts a double-tower alternating operation structure, with one tower for adsorption and one tower for regeneration, realizing 7×24 hours continuous gas production without frequent shutdowns, improving gas efficiency and avoiding production losses caused by gas supply interruptions.

Intelligent and Convenient, Low Maintenance Cost

The equipment is equipped with a PLC programmable control system, which can realize one-key start-stop and real-time parameter adjustment. It has automatic purity monitoring and linked alarm functions. When the oxygen concentration deviates from the set value, an acousto-optic alarm is triggered to ensure the safety of gas quality. High-end models are equipped with a remote monitoring module, which can real-time check operating parameters such as flow rate, pressure, and purity, support docking with hospital SCADA systems or factory MES platforms, realize unattended operation, and greatly reduce manual maintenance costs. In addition, the service life of the core component molecular sieve of the equipment can reach 8000~12000 hours, with a long maintenance cycle and simple operation, further reducing the maintenance burden.

Safe and Reliable, Adapting to Complex Scenarios

Minnuo PSA oxygen generator uses an oil-free air compressor to provide a clean and pollution-free compressed air source, combined with a complete air purification system to remove oil, water, and impurities in the air, avoiding pollution to gas equipment and products. The equipment operates stably at pressure, without the risk of high-pressure gas storage and flammable gases. It is equipped with fault early warning systems such as motor overheating, pressure deviation, and filter blockage. At the same time, it adopts a flame-retardant shell and leak-proof pipelines, which can adapt to harsh industrial environments such as plateaus, high temperatures, and humidity, making it an ideal choice for long-term stable operation.

Modular Design, Flexible Expansion

The equipment adopts a modular structure, covering a small area, with a short on-site installation and commissioning cycle. It can be flexibly adjusted according to the user’s gas demand. The single-machine capacity can be expanded to 20Nm³/h~300Nm³/h, supporting multi-machine parallel expansion to meet the gas demand of enterprises at different development stages, without large-scale site renovation, reducing initial investment costs.

II. Core Advantages of Minnuo PSA Nitrogen Generator

Minnuo Group’s PSA nitrogen generator takes Carbon Molecular Sieve (CMS) as the core adsorbent, relying on precise pressure swing adsorption technology and intelligent control system, focusing on on-site production of high-purity nitrogen. It is widely used in electronic manufacturing, food packaging, chemical storage, metal processing, scientific research experiments and other fields. Compared with traditional gas supply methods such as cylinder nitrogen and liquid nitrogen, it has significant cost performance and convenience advantages.

Adjustable Purity, Meeting Diverse Needs

The purity of Minnuo PSA nitrogen generator can be flexibly adjusted, ranging from 99.5% to 99.9995%. Relying on independently developed high-efficiency carbon molecular sieves (specific surface area of 800-1000 ㎡/g, adsorption capacity increased by 20%) and intelligent control systems, the purity fluctuation is controlled within ±0.001%, which can accurately match the gas demand of different industries. The electronic industry can achieve 99.9995% high-purity nitrogen supply to ensure the stability of processes such as chip manufacturing and electronic component aging; the food industry can provide nitrogen with a purity of more than 99.9% for modified atmosphere packaging to extend the shelf life of food.

Low-Cost Operation, Outstanding Cost Performance

The equipment uses air as raw material, without any chemical reactions or external gas sources. It can realize on-site nitrogen production only by consuming electric energy. The operating cost is only 1/5 of cylinder nitrogen and 1/10 of liquid nitrogen, and the cost per cubic meter of nitrogen is as low as 0.3~0.5 yuan. At the same time, it eliminates the transportation, storage, and rental costs of cylinder nitrogen and liquid nitrogen, avoiding problems such as leakage and loss during transportation. Long-term use can save a lot of expenses for enterprises, especially suitable for enterprises with large gas consumption and frequent gas use.

Continuous and Stable, No Interruption in Gas Supply

Adopting a double-tower alternating adsorption and regeneration design, combined with a large-capacity buffer tank, it can realize 7×24 hours uninterrupted gas supply, which can effectively meet the sudden demand during the gas peak period and avoid affecting the production progress due to gas supply interruption. Compared with the disadvantages of traditional cylinder nitrogen that requires frequent cylinder replacement and liquid nitrogen tanks that need regular replenishment, Minnuo PSA nitrogen generator can realize continuous and stable gas production, greatly improving production efficiency, especially suitable for continuous production enterprises.

Intelligent and Safe, Easy to Operate

Equipped with a PLC intelligent control system, it can realize unattended operation, real-time monitor key parameters such as nitrogen purity, pressure, and flow rate, and has automatic fault alarm and automatic shutdown protection functions. Operators can complete daily operations without professional skills. The equipment operates at low pressure (0.1-0.8MPa), without the risk of high-pressure explosion, and does not need to store liquid nitrogen, avoiding potential safety hazards such as low-temperature frostbite and oxygen deficiency. At the same time, it is equipped with overpressure, overload, and high-temperature protection devices to fully ensure operational safety.
