PSA Oxygen Generator

Product Overview

The Industrial PSA Oxygen Generator produces high-purity oxygen on-site directly from compressed air using Pressure Swing Adsorption technology. Engineered for continuous industrial operation, the system utilizes high-grade ZMS (Zeolite Molecular Sieve) to selectively adsorb nitrogen, delivering a steady stream of dry oxygen at specified pressure and flow rates.
Eliminates liquid oxygen (LOX) bulk delivery logistics, rental fees, and supply chain volatility. Designed for direct integration into existing plant utility networks.

Key Features

Dual-Tower Adsorption Cycle:

Alternating adsorption and regeneration columns ensure continuous, pulsation-reduced oxygen delivery.

Heavy-Duty Pneumatic Valves:

Maintenance-rated for over 1,000,000 switching cycles, minimizing internal leakage and pressure drop.

Automatic Purity Control (APC):

Real-time zirconia analyzer continuously monitors oxygen concentration. Out-of-spec gas is automatically vented via an intelligent purge valve to protect downstream processes.

Integrated Feed Air Treatment:

Multi-stage filtration (refrigerated air dryer, coalescing filters, activated carbon tower) removes moisture, oil aerosols (<0.01 ppm), and particulates before air enters the molecular sieve beds.

Applications

Laser Metal Cutting:

Supplies auxiliary assist gas for carbon steel and stainless steel cutting, reducing operational gas costs compared to high-pressure cylinders.

Aquaculture & Fish Farming:

Increases dissolved oxygen (DO) levels in intensive recirculating aquaculture systems (RAS), supporting higher stocking densities.

Medical Facilities:

Complies with hospital pipeline standards when paired with medical-grade purification packages (eliminating CO, CO2, and moisture).

Glass Working & Ampoule Sealing:

Stabilizes burner flame temperature and intensity.

Customization Options

01/

Integrated vs. Standalone Air Supply: Available as a standalone skid requiring an external clean, dry compressed air source, or as a turn-key integrated system including a matched screw air compressor and receiver tank.

02/

Containerized Turnkey Systems: Integrated into ISO 20ft or 40ft insulated shipping containers complete with HVAC, internal lighting, and ventilation for harsh outdoor environments.

03/

High-Pressure Filling Stations: Coupled with a high-pressure oil-free booster compressor (150 bar) for cylinder filling operations.

04/

Ex-Proof Configuration: ATEX / IECEx certified electrical components and explosion-proof control panels for hazardous chemical plant environments.

Manufacturing & Quality Control

Vessels: Pressure vessels welded in-house under ASME Section VIII standards, subjected to 100% radiographic testing (RT) and hydrostatic testing at 1.5x design pressure.
Piping: Stainless steel (304/316L) process piping argon-arc welded and pressure tested to prevent contamination.
Factory Acceptance Testing (FAT): Every unit undergoes a 72-hour continuous runtime test prior to crating, measuring actual gas output, power draw, and purity stability. Test reports are archived per serial number.

Certifications & Compliance

ISO 9001:2015 Quality Management System certified manufacturing facility.
CE Compliance for electrical safety and machinery directives.
ASME U-Stamp available upon request for pressure vessels.

Packaging & Delivery

Packaging:

Export-grade fumigation-free wooden crates, moisture barrier vacuum-sealed foil lining, and shock-absorbent base anchoring.

Lead Time:

Standard skid-mounted units: 30 to 45 days. Containerized or custom-engineered systems: 60 to 75 days.

Shipping Port:

FOB / CIF from major international ports (Shanghai/Ningbo).

fAQ

Q: How long does the Zeolite Molecular Sieve last?

A: Under proper feed air conditions (oil-free, moisture-free, dew point <= -40°C), the molecular sieve lifespan exceeds 8 to 10 years without replacement.

Q: What is the typical specific power consumption?

A: Power consumption ranges between 0.8 kWh and 1.1 kWh per Nm3 of pure oxygen generated, depending on plant elevation, delivery pressure, and capacity size.

Q: Can the system run unattended?

A: Yes. The Siemens PLC control system features automated startup/shutdown sequences, fault alarms, and remote monitoring capability via Ethernet/Modbus.
