  • Oil & Gas

    This sector is one of the most high-risk environments for fire and explosion, making ATEX smoke and heat detection indispensable.

    • Installed in living quarters, control rooms, compressor rooms, and helidecks to detect smoke from electrical faults or equipment overheating.
    • Deployed in processing units, control buildings, and storage tank zones where flammable gases and vapors are present.
    • Positioned near valves, fuel pumps, and gantries to provide early warning in case of leaks or combustion.
  • Manufacturing and Processing Plants

    Facilities that process volatile chemicals require continuous air monitoring and reliable early fire detection.

    • Solvent Storage Rooms: Detect smoke from spontaneous combustion or faulty electrical equipment.
    • Reactor & Mixing Areas: Placed above or around reactors where exothermic reactions may cause overheating or fires.
    • Cleanrooms & Laboratories: Sensitive enough to detect smoke without disrupting delicate operations; certified enclosure ensures safe installation in explosive environments.
  • Industrial Manufacturing & Fabrication

    Many manufacturing operations involve combustible materials or high-voltage equipment.

    • Prevents ignition of aerosolized paints and solvents.
    • Used near extrusion machines or chemical mixing areas where fumes and particles can become ignition sources.
    • Detects overheating or smoke from spark-prone processes.
