GFx77f
Uncooled Fixed OGI Camera for Hazardous Areas
Keep watch over your most critical assets—without walking the site. For teams responsible for emissions detection across oil and gas and industrial facilities, the FLIR GFx77f brings optical gas imaging into demanding hazardous areas.
This ATEX/IECEx system pairs the uncooled GF77a platform with a rugged enclosure to continuously monitor for methane. When an uncooled detector suits your target gas and monitoring goal, the GFx77f offers a lower-complexity option within the FLIR ADGiLE platform, delivering autonomous leak detection that helps you protect capital equipment, reduce product loss, meet emissions targets and keep workers safer.
See Emissions the Moment They Start—Around the Clock, in Hazardous Areas
The uncooled, spectrally filtered design provides continuous, autonomous leak detection—including patented High Sensitivity Mode (HSM)—so facilities can spot methane emissions and begin repairs immediately, without waiting on manual inspection rounds.
The AISI 316L stainless steel construction is lightweight, corrosion-resistant, and designed for easy installation and maintenance. Install multiple units across a facility to maximize leak detection with fewer in-person inspections.
Open architecture enables simple third-party integration, while dual-streaming thermal plus digital HD IP imagery lets you see more. Add in ONVIF compliance for an ease of integration with standard security and NVR solutions.
The Right Tool for the Right Monitoring Job
When an uncooled detector suits your target gas and site conditions, the GFx77f delivers continuous hazardous-area coverage with less complexity.
- Helps you select fixed monitoring based on site layout, number of areas to observe, and required field of view.
- Small and lightweight, yet packed with patented features such as High Sensitivity Mode (HSM).
- For when a lower-cost option is sufficient to meet leak detection and regulatory compliance goals.
Continuous Coverage Where It Matters Most
The GFx77f is developed for optical gas imaging applications for gas leak detection in LNG processing plants, wellpads, and compression stations—providing a constant eye on the assets most prone to emission events.
- Facility and asset monitoring — Fixed-position, uncooled OGI configuration for continuous observation of a defined asset or facility area.
- Pressure-relief and valve surveillance — Continuously watch high-risk points such as storage-tank relief valves and compressor valves.
- Critical asset focus — Focus on your most critical equipment to ensure optimal operating conditions.
From Detection to Response, Automatically
The GFx77f streamlines the leak-monitoring workflow by replacing periodic manual inspections with always-on, autonomous observation.
- Monitor — Provides continuous, autonomous leak detection across the monitored area.
- Detect — As part of ADGiLE, the GFx77f monitors for and detects methane emissions so you can begin repairs immediately.
- Confirm — Open architecture allows third-party analytic solution integration for visual confirmation of a leak.
- Act — Help you better maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices.
