Pyrex-XL Gas Agent Extinguisher

During the design and modernization of armored combat vehicles, effective use of internal volume is a critical engineering requirement. Conventional fire suppression cylinders discharge the extinguishing agent directly from a fixed location, which can create installation difficulties—especially in tank modernization programs and compact armored vehicle platforms.

To overcome these limitations, Nero Industries has developed the Pyrex-XL Gas Agent Extinguisher, offering increased suppression capacity while maintaining flexibility in system layout and integration.

The Pyrex-XL system delivers fire suppression performance within the same activation duration defined by NATO STANAG 4317, ensuring no compromise in operational safety.

By integrating a hose-based discharge configuration, the Pyrex-XL extinguisher allows the extinguishing agent to be delivered precisely to critical fire-risk zones, even when direct cylinder placement is not feasible.

The hose line can be extended up to 2 meters by increasing internal cylinder pressure, enabling improved coverage and optimized placement within the vehicle.

Pyrex-XL extinguishers with gas agents are specialized fire suppression devices designed to extinguish fires using clean and efficient gas agents, including:

• CO₂

• HFC-227ea (FM-200)

• Inergen

These extinguishers are particularly suitable for confined spaces, sensitive equipment zones, and environments where residue-producing extinguishing agents are not acceptable.

• High Suppression Capacity: Enhanced extinguishing performance for high-risk areas

• Rapid Response: Pyrotechnic activation within 3 milliseconds

• Clean Agent Technology: No dust, residue, or post-fire cleanup required

• Minimal Combustion Risk: Safe discharge without ignition risk

• Lightweight Construction: Aluminum body for improved handling and integration

• Wide Environmental Capability: Operational between -32°C and +120°C

CO₂ Fire Extinguishers

• Agent: Carbon dioxide (CO₂)

• Mechanism: Displaces oxygen to suppress combustion

• Applications: Electrical fires and confined spaces

Inergen Fire Extinguishers

• Agent: Gas mixture simulating atmospheric air

• Mechanism: Reduces oxygen concentration while remaining safe for occupants

• Applications: Data centers and archive rooms

HFC-227ea / FM-200 Fire Extinguishers

• Agent: HFC-227ea (FM-200)

• Mechanism: Heat absorption with secondary chemical flame inhibition

• Applications: High-risk areas with flammable materials and electronic equipment

• Bank vaults and secure storage areas

• Rare book stores and archives

• Telephone exchanges and communication centers

• Control rooms and electronic data processing facilities

• Transformer and switch rooms

• Test laboratories

• Marine and naval systems

• Military and armored vehicles

Pyrex-XL gas agent extinguishers are designed and tested in accordance with internationally recognized standards:

• NFPA 2001 – Clean Agent Fire Extinguishing Systems

• ISO 14520 – Gas Fire Suppression Performance

• UL 2127 – Gas-Based Fire Suppression Certification

• EN 15004 – European Fire Suppression Standards

• MIL-STD-810H – Environmental and military durability tests

The extinguisher cylinders have successfully passed high-temperature, low-temperature, humidity, and environmental tests required for military applications.

FM-200® is a colorless, non-toxic clean agent designed to protect high-value assets in normally occupied spaces. It is especially suitable where:

• Cleanup of other agents is problematic

• Storage space for extinguishing agents is limited

• Electrically non-conductive fire suppression is required

FM-200 fire suppression systems are designed to discharge within 10 seconds into an enclosed area capable of retaining the agent. The primary extinguishing mechanism is heat absorption, with a secondary chemical contribution during flame interaction.

FM-200 leaves no residue and is safe for use in occupied environments.
