The EPD-120N Twin-Tower Nitrogen Generator is a high-capacity PSA nitrogen production system designed for industrial applications requiring a large and continuous supply of high-purity nitrogen. With an output of 120 Nm³/Hr and a purity of up to 99%, this generator ensures reliable performance, energy efficiency, and low operating costs. Equipped with intelligent PLC control and premium components, the EPD-120N is ideal for demanding environments such as metal processing, chemical plants, and electronics manufacturing.
High Flow Output
Delivers 120 Nm³/Hr of nitrogen at 99% purity (up to 99.999% optional).
Operating pressure: 0.1–0.7 MPa, with dew point ≤ -40°C.
Energy Efficient & Economical
Low air consumption: 4.4 m³/min at 99% purity.
Variable Cycle Control (VP Logic) saves 20%–60% energy by adjusting cycle time based on actual load.
Smart Control & Monitoring
PLC + 7-inch Touch Screen for operation and real-time data display.
Supports remote control, fault alarms, and Modbus/RS485 communication.
Robust & Long-Lasting Design
Adsorption towers manufactured in compliance with GB150 standards.
Stainless steel pneumatic valves with Y-type design, rated for 3 million+ cycles.
Blizzard + Vacuum + Vibration filling technology ensures dense sieve packing and extends service life.
Automatic Purity Assurance
Built-in gas analyzer with electrochemical sensor (3+ years lifespan).
Auto-exhaust system discharges off-spec nitrogen to ensure consistent output quality.
