The EPD-550N Twin-Tower Nitrogen Generator is a high-capacity, energy-efficient system engineered to deliver nitrogen gas with a purity of up to 99% at a flow rate of 550 Nm³/Hr. Utilizing advanced Pressure Swing Adsorption (PSA) technology, it ensures reliable and stable performance for a wide range of industrial applications. 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.
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.
