The technical indicators of the dual-tower PSA oxygen generator cover core performance, energy efficiency, environmental adaptability and system characteristics. The following are the key parameters:
1. Basic performance indicators
Oxygen purity
Medical field: usually required ≥90%; some scenarios (such as respiratory support) require ≥93%.
Industrial application: generally ≥80%, special processes (such as metallurgy, chemical industry) may require higher purity (such as above 95%).
Flow range
Medical equipment: commonly 5-10 L/min, large hospital equipment can reach tens to hundreds of Nm³/h.
Industrial equipment: single unit flow covers 0-300 Nm³/h, customized needs can be expanded to higher flow.
Output pressure
Standard outlet pressure: 0.3-0.5 MPa, some industrial scenarios need to be pressurized to more than 0.5 MPa.
2. Energy efficiency and environmental adaptability
Energy consumption indicators
Unit energy consumption: usually expressed in kWh/Nm³, high-efficiency models can reach 0.3-0.5 kWh/Nm³.
Actual power consumption: needs to be calculated in combination with auxiliary equipment such as air compressors and cold dryers.
Altitude adaptability
Design parameters need to be adjusted in high altitude areas, such as optimizing adsorption pressure and flow rate, to compensate for the impact of low oxygen environment on purity.
Dew point control
Normal pressure dew point: ≤-40℃ (conventional standard); if lower humidity is required (such as precision industry), drying equipment can be configured to -50℃.
3. System characteristics and technical requirements
Automation and reliability
Support PLC control of fully automatic operation, real-time monitoring of oxygen purity, pressure and other parameters.
Start-up time: qualified oxygen can be produced within 15 minutes.
Maintenance and life
Molecular sieve life: usually 3-5 years (depending on frequency of use and air cleanliness).
Maintenance cost: much lower than traditional liquid oxygen system, annual maintenance cost is about 5-10% of the initial investment.
4. Other key parameters
Power requirements
Input voltage: adapt to 220V/380V according to the region, and voltage fluctuation stability needs to be considered.
Safety standards
Comply with explosion-proof design (such as chemical, oil and gas industries), equipped with oxygen concentration alarm and automatic shutdown protection.
