The EPD-400N Twin-Tower Nitrogen Generator is a high-performance, energy-efficient system designed to produce nitrogen with a purity of up to 99% and a flow rate of 400Nm³/Hr. Utilizing Pressure Swing Adsorption (PSA) technology, this generator ensures stable and reliable nitrogen output, making it ideal for various industrial applications. Equipped with an intelligent PLC control system and advanced carbon molecular sieve, it offers low air consumption, high efficiency, and long-term durability.
High Purity & Stable Output
Nitrogen Purity: Up to 99%
Flow Rate: 400 Nm³/Hr
Dew Point: ≤ -40°C
Output Pressure: 0.1–0.7 MPa
Energy-Saving & Intelligent Control
VP (Variable Period) Control Logic automatically adjusts the cycle time based on actual load:
80% load → 70s cycle → 20% air saving
50% load → 100s cycle → 50% air saving
30% load → 130s cycle → 60%+ energy saving
Equipped with PLC + 7-inch Touchscreen for real-time monitoring and remote communication.
Advanced Filling Technology
Uses Blizzard + Vacuum Loading + Vibration Platform to ensure tight and stable molecular sieve packing.
Increases molecular sieve loading volume by ≥15% and prevents powdering during transport.
Durable & Reliable Components
All Stainless Steel Pneumatic Valves with Y-type design, rated for 3 million+ cycles (approx. 6+ years).
Digital Flowmeter & Pressure Sensors for accurate monitoring.
Long-Life Electrochemical Sensor (over 3 years) for precise purity analysis.
Automatic Purity Protection
Impure Nitrogen Auto-Exhaust System ensures only high-purity nitrogen is delivered.
No manual intervention required.
