Equipped with an intelligent PLC control system, high-quality carbon molecular sieve, and robust components, this generator offers superior efficiency, low operating costs, and long-term durability.

Key Features

High Purity & High Flow Output

• Nitrogen Purity: Up to 99%

• Flow Rate: 550 Nm³/Hr

• Dew Point: ≤ -40°C

• Output Pressure: 0.1–0.7 MPa

Intelligent Energy-Saving Control

• VP (Variable Period) Control Logic automatically adjusts cycle time based on real-time load:

  • 80% load → 70s cycle → 20% less air consumption

  • 50% load → 100s cycle → 50% less air consumption

  • 30% load → 130s cycle → Over 60% energy saving

• PLC + 7-inch Touch Screen enables easy operation and remote monitoring via Modbus/RS485.

Advanced Molecular Sieve Filling Technology

• Combines Blizzard + Vacuum Loading + Vibration Platform for dense and stable packing.

• Increases molecular sieve loading volume by ≥15% and prevents powdering during transit.
