EPD-90N Twin-Tower Nitrogen Generator 99% Purity 90Nm³/Hr Industrial Grade PLC & Touch Screen Control

Product Overview

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.

Key Features

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.
