Gaseous System Fire Protection

  • Fire Detection is made by our Spy Thermo Sensitive technology.
  • 1 Single Line for Detection and Extinguishing.
  • Each cabinet is protected individually.
  • System can be activated independently in the place that has the fire due to the directional valve system protecfire developed.

Fire Protection for locations where liquids cannot be present.

The Directional Valve Control


  • The System can be installed multiple compartments
  • Detects and Extinguish only in the compartment that triggered the thermo-pneumatic detector.
  • Less equipment
  • Best budget 
  • More efficiency in the amount of gas sent to the fire spot.
  • Can be used for mobile parts

Compact and directional

detexAn2 it’s extremely compact and fits virtually anywhere. 

This system is designed to fit in small places and vehicles where operators are present. 

DETEX AN² inert gas fire protection systems allow through their intelligent design a very compact and space-saving storage of the extinguishing agent. Both extinguishing agents are stored separately in fully welded 2-litre steel tanks at 250 bar. Through the selected dimensions of the steel cylinders (80 mm diameter and approx. 600 mm total length) an installation option is always found and this even in very confined spaces. The 250 bar technology allows the use or installation of these extinguishing systems even in extreme temperature conditions, from -60°C to + 80°C.

Ideal for special applications military / offshore

DETEX An2 inert gas fire protection systems fight fires through the supply of Argon and Nitrogen to reduce the oxygen content to below 15% in the space to be protected. They are especially suitable for the protection of small rooms up to 2m ³ with sensitive and high quality installations, where residue-free extinguishing is required without the use of chemical gases, water, foam or powder as extinguishing agent.

Inert gases have a first-class extinguishing effect for fires of class A (solids), B (flammable liquids) and C (flammable gases). Argon is also suitable as the only fire extinguishing gas also for class D (metal fires).

  • It can be installed in any position or angle
  • It can be installed on moving gears / machinery

protecfire detection is a state-of-the-art engineering solution.
Pneumatic detector works with argon gas, that is triggered by a temperature fuse.
