The EPD-90N Twin-Tower Nitrogen Generator is a robust and efficient PSA (Pressure Swing Adsorption) nitrogen production system, capable of delivering 90 Nm³/Hr of nitrogen gas at a purity of up to 99%. Designed for industrial applications requiring a continuous and reliable nitrogen supply, this system integrates advanced control technology, high-quality components, and an energy-saving design to ensure optimal performance and low operating costs.
High Flow & Stable Purity
Nitrogen output: 90 Nm³/Hr at 99% purity (configurable up to 99.999%).
Stable outlet pressure: 0.1–0.7 MPa, with dew point ≤ -40°C.
Energy Efficient Operation
Low air consumption: only 3.3 m³/min at 99% purity.
Variable Cycle Control adjusts adsorption time based on real-time load, saving 20%–60% in energy.
Intelligent Control System
PLC + 7-inch Touch Screen for easy operation and monitoring.
Supports remote start/stop, fault alarm, and Modbus/RS485 communication.
Durable Construction & Long Life
Adsorption towers built to GB150 standards for safety and durability.
Stainless steel pneumatic valves with Y-design, rated for 3 million+ cycles.
Blizzard + Vacuum + Vibration filling technology ensures dense molecular sieve packing and longer service life.
Automatic Purity Protection
Built-in gas analyzer with electrochemical sensor (3+ years lifespan).
Auto-drain valve discharges sub-standard nitrogen to ensure output quality.
