Applications
-
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.
