The EPD-500N Twin-Tower Nitrogen Generator is a robust and efficient system designed to deliver high-purity nitrogen up to 99% at a flow rate of 500 Nm³/Hr. Utilizing advanced Pressure Swing Adsorption (PSA) technology, it ensures consistent and reliable performance for a wide range of industrial applications. Equipped with an intelligent PLC control system and premium carbon molecular sieve, this generator offers exceptional energy efficiency, low operating costs, and long-term durability.
High Purity & Large Flow Output
Nitrogen Purity: Up to 99%
Flow Rate: 500 Nm³/Hr
Dew Point: ≤ -40°C
Output Pressure: 0.1–0.7 MPa
Intelligent Energy-Saving Control
VP (Variable Period) Control Logic 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 for easy operation and remote monitoring via Modbus/RS485.
Advanced Molecular Sieve Filling Process
Combines Blizzard + Vacuum Loading + Vibration Platform for dense and stable packing.
Increases molecular sieve loading volume by ≥15% and prevents powdering during transit.
Ensures stable performance for up to 5 years without replenishment.
