The Filosha Fixed Flammable Gas Detector is a permanently mounted point detector that guards plant against the build-up of combustible gases and vapours. Available with catalytic bead or infrared sensing, it measures concentration as a percentage of the lower explosive limit and drives alarms and shutdown systems. ATEX-certified and weatherproof, it delivers continuous, reliable protection in hazardous areas.
The Filosha Fixed Flammable Gas Detector provides round-the-clock surveillance for combustible hazards across process facilities, delivering an early, quantified warning long before an explosive atmosphere can form. Mounted to walls, structural steel or process skids, the detector continuously measures the concentration of flammable gases and vapours as a percentage of the lower explosive limit (LEL) and transmits a signal to the plant control or fire-and-gas system. Catalytic bead sensing offers a proven, cost-effective solution for a broad spread of hydrocarbons, while infrared sensing suits applications requiring immunity to sensor poisoning and dependable performance in oxygen-lean or inert conditions.
Housed in a robust flameproof enclosure and certified for ATEX hazardous-area installation, the detector is built to withstand the heat, humidity, dust and corrosive atmospheres encountered across the GCC and India. A local display and status indicators allow readings and alarm conditions to be verified at the point of installation, while standard analogue and digital outputs integrate cleanly with existing controllers. Non-intrusive calibration and accessible sensor replacement reduce maintenance downtime and keep the device in service. Whether protecting a compressor house, a loading gantry or a process module, the Fixed Flammable Gas Detector forms a core layer of any fixed fire-and-gas strategy, safeguarding personnel, assets and continuous operations.
