High Efficient VPSA Oxygen Generator / VPSA Oxygen Plant For Metal Cutting And Welding

• 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.

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

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.

• 24/7 oxygen production with direct pipeline delivery
• Stable pressure and purity ensures consistent cutting/welding quality
• Eliminates production delays from gas cylinder delivery

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

• Lower pressure (below 15 bar) reduces leakage/explosion risks
• Eliminates high-pressure cylinder management
• On-demand oxygen with simple valve operation

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