EX Type Hydrogen Purification System 10-3000Nm3/h ATEX IEC GB

The Explosion-Proof Hydrogen Purification System is a cutting-edge solution designed to deliver ultra-high-purity hydrogen by removing moisture, oxygen, and other contaminants from raw hydrogen streams. Engineered with safety and reliability at its core, this system integrates advanced adsorption, catalytic reaction, and PLC automation technologies, making it ideal for hazardous environments in industries such as energy storage, chemical processing, electronics manufacturing, and fuel cell applications.

• Global Certification Compliance: Equipped with an EX-type control panel and EX-rated electrical components, the system meets rigorous explosion-proof standards, including GB (China), IEC (International), and ATEX (EU). This ensures safe operation in Zone 1/2 hazardous areas where flammable gases may be present.
• IP65 Protection: All electrical parts boast an IP65 ingress protection rating, shielding against dust, water jets, and harsh industrial conditions, ensuring long-term durability in demanding settings.

• Efficient Moisture Removal: The system features two dedicated drying towers filled with high-performance adsorbents (e.g., molecular sieves) to eliminate water vapor. The automatic regeneration cycle (150-180°C) ensures continuous operation without manual intervention, maintaining consistent performance.
• Exceptional Dew Point Performance: Delivers outlet hydrogen with a dew point of ≤ -70°C at 1 ATM, critical for applications requiring dry hydrogen to prevent corrosion, catalyst poisoning, or equipment failure.

• Catalytic Oxygen Elimination: A specialized oxygen removal tower with palladium-based catalysts enables efficient O₂ removal at ambient temperature. Oxygen reacts with residual hydrogen to form water, which is then adsorbed by the drying towers, ensuring oxygen levels are reduced to ppm levels.

• Fully Automated Processes: The entire purification cycle--including adsorption, regeneration, and tower switching--is controlled by a programmable logic controller (PLC). This minimizes human error, optimizes energy use, and allows for seamless integration with SCADA or industrial monitoring systems.
• User-Friendly Interface: The EX-type control panel provides real-time data on pressure, temperature, dew point, and system status, with alarm functions for abnormal conditions (e.g., high pressure, low flow).

This system combines explosion-proof safety, ultra-high purity output, and automated operation to address the critical needs of modern industrial hydrogen applications. Whether for fuel cell vehicles, energy storage, or precision manufacturing, it delivers reliable, cost-effective performance while adhering to the strictest global safety norms.
