Explosion-Proof PSA Nitrogen Generator 95-99.9995% Purity 0-8bar

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.

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.

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.

GASPU's ATEX/IECEx Certified Explosion-Proof PSA Nitrogen Generators deliver reliable, on-site nitrogen production where safety is paramount. Eliminate the risks and costs associated with gas cylinders while ensuring compliance in your Zone 1/2 or Zone 21/22 environment.
