Introducing the Fgard H2 by Crowcon, a breakthrough in Hydrogen Flame Detection. The FGard H2 delivers first-in-class flame detection with intelligent heated optics for clearer results and advanced optical verification to greatly reduce false alarms
In industries reliant on hydrogen, the inherent challenge of detecting its colorless gas and flame presents a critical safety concern. Traditional multi-spectral flame detectors are insufficient for this task, as they lack the capability to discern hydrogen flames. Fgard H2 is optimised exclusively for hydrogen flame detection, ensuring your people and your facilities are kept safe.
Fgard H2 delivers unparalleled performance, with a response time of just 4 seconds. This remarkable speed is validated for a 36-inch plume size hydrogen flame at a distance of 40 meters, ensuring swift and reliable detection even in demanding industrial environments.
Intelligent heated optics – No condensation / ice / water.
Automatic test verifies cleanliness of the lens and electronic circuitry. No reflector optical check and large optical surface results in far fewer false alarms.
Setting a new standard in reliability, Fgard H2 comes with a market-leading 5 year warranty period for a hydrogen flame detector. This commitment to quality is underscored by the endorsement of Factory Mutual (FM), validating the performance of Fgard H2.
