50kW Low-Power-Consumption PSA Oxygen Generator for Mine Emergency Rescue
The working environment in underground mines is complex; sudden accidents such as collapses and gas leaks can easily cause oxygen deficiency and suffocation among personnel, so fast and stable oxygen supply is crucial for successful emergency rescue. As the core equipment for mine emergency rescue, the Pressure Swing Adsorption Oxygen Generator is based on Pressure Swing Adsorption Oxygen Generation Technology. It separates air components selectively through adsorbents and can produce high-purity oxygen within a few minutes.
This 50kW low-power-consumption model integrates the energy-saving advantages of VPSA Oxygen Supply Systems, reducing power consumption by 25% compared with traditional equipment. It also features portability, mobility and impact resistance, which perfectly adapts to the narrow space and unstable power supply environment in mines, building a reliable "life defense line" for underground emergency rescue.

Why PSA Oxygen Generator is the First Choice for Mine Emergency Rescue
Mine emergency rescue has extremely strict requirements for oxygen supply equipment, namely "fast, stable and economical", and the Pressure Swing Adsorption Oxygen Plan precisely meets these needs. Traditional mine emergency rescue mostly relies on bottled oxygen; a single bottle can only supply one person for 2 hours, and transportation is difficult.
In contrast, the 50kW PSA oxygen generator can produce 480-720Nm³ of oxygen per day (24 hours), equivalent to the oxygen volume of 3200-4800 bottles of bottled oxygen. Meanwhile, its Pressure Swing Adsorption Oxygen Supply System does not require liquid oxygen storage, avoiding the explosion risk under high temperature and pressure, thus being more suitable for the flammable and explosive environment in mines. Compared with Vacuum Swing Adsorption Oxygen Plant, this equipment can still maintain stable oxygen production under low-power operation, adapting to the limited power supply capacity of mine emergency generators.
Cost Analysis for PSA Oxygen Plant in Mine Emergency Scenarios
When selecting equipment, mining enterprises focus on the comprehensive cost in emergency scenarios in addition to the initial investment. The PSA Oxygen Generator Price of the 50kW model is approximately 150,000-200,000 RMB. Although it is higher than that of small equipment, it reduces the cost by 50% compared with the establishment of a bottled oxygen reserve warehouse.
In terms of operating cost, the energy consumption cost per cubic meter of oxygen is about 0.36 RMB (calculated based on the industrial electricity price of 0.6 RMB/kWh), which is only 1/4 of that of bottled oxygen. Besides, the equipment uses special dust-resistant molecular sieves with a service life of up to 4 years, which is much longer than that of ordinary PSA equipment, reducing maintenance and replacement costs. For a mine with an annual output of 1 million tons, equipping one such equipment can save more than 100,000 RMB in emergency oxygen supply costs every year.
Extreme Environment Adaptability: Specialized Mine Scenario Designs
To cope with the extreme environment in underground mines, the equipment has multiple special designs:
- Impact-resistant steel plate construction to withstand falling rocks in mines
- Explosion-proof electrical system compliant with underground coal mine safety standards
- Integrated dehumidification system ensuring proper air pretreatment even in 90% humidity conditions
- Waterproof and dustproof touch control panel for easy operation with gloves
- Mine emergency communication system integration for remote activation and oxygen supply preparation
In conclusion, the 50kW low-power-consumption PSA oxygen generator has become the core equipment for mine emergency rescue due to its advantages of stability, energy saving and portability. Through the integration of Pressure Swing Adsorption Oxygen Production Technology and vacuum regeneration technology, it provides continuous and reliable oxygen support for trapped personnel in extreme environments, which not only reduces the emergency cost of mining enterprises but also builds a solid life defense line.
