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, , 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:
- 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.
- 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.
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)
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.
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.
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.
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.
