High Efficient And Low Cost VPSA Oxygen Generator / VPSA Oxygen Plant for Metal Cutting and Welding
Why does metal cutting and welding require oxygen?

The core function of oxygen in metal processing is to assist combustion and oxidation.

Cutting Process (Oxyacetylene and Plasma Cutting)
  • Flames first heat the metal to its ignition point (approximately 870°C for steel)
  • High-speed pure oxygen stream sprayed onto the heating point causes violent oxidation reaction
  • Generates metal oxides (slag) while releasing large amounts of heat
  • Oxygen flow blows away slag, forming a slit for cutting

Oxygen purity and pressure directly determine: cutting speed, effectiveness, and incision neatness.

Welding Process (Oxyacetylene Welding)

Oxygen mixed with combustible gases (acetylene, propane) produces high-temperature flame to melt base material and welding material.

Advantages of VPSA Technology Over Traditional Methods
Problems with Bottled Oxygen (Oxygen Cylinders)
  • High cost: Oxygen price plus transportation, loading, and rental costs
  • Low efficiency: Frequent cylinder replacement interrupts production
  • Safety hazards: High pressure cylinders pose storage/transport risks
  • Purity fluctuation: Decreases when cylinder pressure is low
Problems with Liquid Oxygen (LOX)
  • Evaporation loss: 0.4%-0.6% daily loss even when unused
  • Supply dependence: Requires regular tanker deliveries
  • Initial investment: Expensive storage tanks and vaporization equipment
VPSA Oxygen Generator Solution

VPSA (Vacuum Pressure Swing Adsorption) technology separates oxygen from air (78% nitrogen, 21% oxygen) using molecular sieves that adsorb nitrogen.

Workflow Process
  1. Compressed air
  2. Pre-treatment (water, oil, dust removal)
  3. Pressure swing adsorption tower (nitrogen adsorbed, oxygen passes)
  4. Finished oxygen (93% ± 3%)
  5. Pressurized transport to point of use
VSA Oxygen Generator system for industrial applications
Key Benefits for Metal Cutting and Welding
1. Significant Cost Reduction

Raw material is free air with main cost being electricity. For medium-large metal processing plants, VPSA oxygen costs only 20%-40% of bottled oxygen.

ROI: 1-3 year payback period followed by minimal operational costs.

2. Stable, Continuous Oxygen Supply
  • 24/7 oxygen production with direct pipeline delivery
  • Stable pressure and purity ensures consistent cutting/welding quality
  • Eliminates production delays from gas cylinder delivery
3. Optimal Purity for Industrial Applications

90%-95% purity perfectly matches metal cutting and welding requirements. Higher purity (99.5%+) would be wasteful for these applications.

4. Enhanced Safety and Convenience
  • Lower pressure (below 15 bar) reduces leakage/explosion risks
  • Eliminates high-pressure cylinder management
  • On-demand oxygen with simple valve operation
Global Applications

Our VSA Oxygen Generators have been successfully implemented in operations worldwide including:

  • Philippines
  • Russia
  • Myanmar
  • Indonesia
  • Ghana
  • Algeria

Summary: For metal processing industries with high oxygen consumption, VPSA oxygen generators are essential cost-reducing and efficiency-enhancing facilities.
