Explosion-Proof PSA Nitrogen Generator | ATEX/IECEx Certified | Safe N2 for Hazardous Areas

Generate Nitrogen Safely Where It's Needed Most

PSA (Pressure Swing Adsorption) Nitrogen Generators revolutionize on-site gas production, delivering high-purity nitrogen directly at your facility for on-demand use. Operating at low pressures, they offer a remarkably cost-effective and environmentally friendly solution compared to traditional gas supply methods. The PSA process relies purely on physical adsorption, featuring a simple structure with no chemical reactions, ensuring zero environmental impact. Built for longevity, standard designs exceed a 10-year service life, with options available for up to 25 years based on customer requirements.

However, standard equipment isn't suitable for locations where explosive atmospheres (gases, vapors, mists) or combustible dusts may be present – common in industries like oil & gas, chemical processing, pharmaceuticals, mining, and paint manufacturing. For these critical environments, GASPU's Ex-Type Explosion-Proof PSA Nitrogen Generators are engineered to provide inherently safe operation.

Key Features & Advantages of GASPU Ex-Type Generators:

1. Certified Safety: The core control system is housed within an ATEX or IECEx certified explosion-proof enclosure, rigorously tested and approved for use in hazardous zones.
2. Hazardous Area Compatibility: Designed to meet the stringent requirements for Zone 1 & Zone 2 (Gas Groups IIA, IIB, IIC) and Zone 21 & Zone 22 (Dust) environments, providing flexibility across various risk levels.
3. Intrinsically Safe Components: All critical electrical components within hazardous zones, including specially designed explosion-proof solenoid valves, are certified. Valves often feature Ex d (Flameproof) or Ex e (Increased Safety) protection, allowing safe direct installation within the classified area for easier maintenance.
4. Temperature Safety: Units comply with Temperature Class T4, T5, or T6 (Tc ≤ 135°C, ≤ 100°C, ≤ 85°C), ensuring surface temperatures never ignite the surrounding atmosphere even under fault conditions.
5. Robust Build & Longevity: Constructed using non-sparking materials and pressurized enclosures where applicable, following the same durable design principles as standard GASPU generators for a >10-year lifespan.
6. Cost & Operational Efficiency: Retains the core PSA advantages: low operating pressure for minimal energy consumption, on-demand production eliminating supply logistics and cylinder rental, and near-zero environmental impact from the physical separation process.

Choosing Your Explosion-Proof Generator Model:

GASPU models follow a clear naming convention: NGXN-Y

• X: Represents the Nitrogen Purity level (e.g., 95, 99, 999, 9995, 9999 %).
• Y: Represents the Nitrogen Flow Capacity (e.g., 5, 10, 20, 50, 100 Nm³/h... up to 2000 Nm³/h).

Example: NG99N-50 = 99% Purity, 50 Nm³/h Flow Capacity.

Frequently Asked Questions (FAQ)

1. Q: What's the difference between ATEX and IECEx certification?

   • A: ATEX is the mandatory certification for equipment placed on the EU market for use in hazardous areas. IECEx is an international certification scheme facilitating global market access. Many manufacturers, like GASPU, certify their Ex equipment to both standards to ensure worldwide applicability. The core safety requirements are harmonized.

2. Q: Why do I need an explosion-proof generator instead of a standard one?

   • A: If your generator will be installed or operated in an area classified as Zone 1/2 (gases/vapors/mists) or Zone 21/22 (dusts), standard electrical equipment poses a significant ignition risk. Ex-Type generators use specially designed and certified enclosures, components, and wiring methods to prevent sparks or hot surfaces from igniting the surrounding atmosphere.

3. Q: What does the Temperature Class (T4, T5, T6) mean?

   • A: It defines the maximum surface temperature the equipment can reach under fault conditions. This temperature must be lower than the Auto-Ignition Temperature (AIT) of the specific gas or dust present in the hazardous area. T6 (≤85°C) is the safest, suitable for gases with very low AIT, while T4 (≤135°C) is suitable for gases with higher AIT. The required T-Class depends on your specific site hazards.

4. Q: How is maintenance handled on an explosion-proof generator?

   • A: Maintenance must be performed by trained personnel following strict procedures to maintain the explosion-proof integrity. Key aspects include ensuring power is isolated before opening enclosures, correctly reassembling flame paths with approved gaskets/seals and torque settings, and using only certified replacement parts for Ex components. The modular design, including externally mounted Ex valves, simplifies access compared to accessing valves inside a pressurized cabinet.
