PSA/VPSA Oxygen and Nitrogen Generation System Solutions

Q: 1.Is the equipment energy-intensive?

PSA Oxygen: 0.35-0.4kWh/Nm³ (93% purity). VPSA Oxygen: 0.28-0.32kWh/Nm³ (90% purity). PSA Nitrogen: 0.1-0.15kWh/Nm³ (99.9% purity). Energy-saving tip: Larger VPSA scale results in lower unit energy consumption.

Q: 2.Is equipment maintenance complicated?

Routine Maintenance: Only requires filter replacement every 6-12 months. Core Components: Molecular sieve warranty for 10 years, valve warranty for 20 years. Intelligent Monitoring: PLC system provides real-time monitoring and automatic fault alarms. Remote Support: Cloud-based remote diagnostics and predictive maintenance. Air filters: Regularly check and replace the filter elements to ensure clean air intake. Cooling system: Whether air-cooled or water-cooled, regularly check the cooling efficiency to prevent overheating. Moving parts: Periodically inspect the wear on piston rings and seals to ensure smooth operation. Pressure and temperature checks: Ensure the equipment operates within the recommended pressure and temperature ranges to avoid damage from excessive pressure or heat. These simple maintenance steps can effectively extend the equipment’s lifespan and maintain efficient, stable operation.

Q: 3.How is after-sales service guaranteed?

Warranty Period: 1 year for the whole machine, 10-20 years for core components Technical Support: 7×24h online response Training Services: Free operation and maintenance training Spare Parts Supply: Global warehouse network for fast delivery

Q: 5.How to get a quote?

Simply provide the following information for an accurate quote: Gas type (oxygen/nitrogen) Flow rate requirement (Nm³/h) Purity requirement (%) Pressure requirement (Mpa) Installation environment (altitude/temperature)
