EPD-350N Twin-Tower Nitrogen Generator 350Nm³/Hr 99% Purity Industrial Grade PLC Control

Product Overview

The EPD-350N Twin-Tower Nitrogen Generator is a high-capacity industrial system designed to deliver 350 Nm³/Hr of nitrogen at 99% purity using advanced Pressure Swing Adsorption (PSA) technology. Engineered for heavy-duty applications, it combines robust construction with intelligent control and energy-saving features, providing a reliable and cost-efficient on-site nitrogen solution for large-scale operations.

Key Features & Benefits

• High-Capacity Output
  Generates 350 Nm³/Hr of nitrogen at 99% purity with stable pressure from 0.1 to 0.7 MPa.

• Energy-Saving VP Control
  Variable Period logic adjusts cycle time based on real-time demand, reducing air consumption by up to 60% under low load.

• Advanced Adsorption System
  High-quality carbon molecular sieves and cyclone gas diffusion ensure efficient and durable O₂/N₂ separation.

• Smart PLC Control
  7-inch touchscreen HMI with remote monitoring and Modbus (RS485) communication for easy operation and data access.

• Robust & Low Maintenance
  All-stainless-steel pneumatic valves rated for over 3 million cycles (approx. 6+ years) ensure long-term reliability.

• Auto Purity Protection
  Integrated gas analyzer and automatic exhaust system ensure only qualified nitrogen is delivered.

• Oil & Gas Inerting and Blanketing

Why Choose EPD-350N?

• High Efficiency & Reliability
  Standard unequal pressure equalization design enhances purity and reduces compressed air consumption.

• Optimized Filling Process
  Blizzard + vacuum + vibration filling increases molecular sieve loading by ≥15%, preventing sinking and chalking for up to 5 years of stable performance.

• Automatic Quality Assurance
  Unqualified nitrogen is automatically vented, ensuring only high-purity gas reaches your process.

• Proven Energy Savings
  VP control logic adapts to load changes, saving 20%–60% on air consumption depending on demand.
