Crowcon FGard flame detectors are explosion-proof optical detectors that identify fires within seconds in hazardous and high-risk industrial areas. The range includes the multi-spectrum infrared FGard IR3, the ultraviolet/infrared FGard UVIR and the FGard H2 for hydrogen fires. Akan Industrial and Automation supplies FGard detectors in Türkiye and integrates them with fire & gas control systems.
How optical flame detection works
Flame detectors sense radiation emitted by a fire in specific infrared and/or ultraviolet bands. Multi-spectrum IR detectors compare several IR wavelengths to distinguish hydrocarbon fires from hot objects and sunlight; UV/IR detectors require both ultraviolet and infrared signatures before alarming.
Crowcon flame detector range
| Model | Technology | Key characteristics |
|---|---|---|
| FGard IR3 | Multi-spectrum infrared | Explosion-proof; hydrocarbon liquid and gas fires at long distances; heated optics; optical verification |
| FGard UVIR | Ultraviolet / infrared | Explosion-proof; detects hydrocarbon fires not visible to the eye; adjustable sensors for harsh conditions |
| FGard H2 | Hydrogen flame detection | Heated optics and optical verification to reduce false alarms |
Typical applications
- Process units, pump stations, loading racks and tank farms
- Gas turbines, compressors and fuel gas skids
- Hydrogen electrolysers, compressors and storage
Why choose Akan?
Akan positions detectors based on fire scenarios and coverage, and connects them to HS81 fire & gas panels or Crowcon controllers. See also our fire protection engineering services.
