Dräger Flame 1750 H₂ (IR3)

Multi-Spectrum Triple Infrared Hydrogen Flame Detector

The Dräger Flame 1750 H₂ (IR3) is a premium, explosion-proof optical flame detector specifically engineered for the rapid detection of hydrogen (H₂) fires. Because hydrogen burns with a pale, near-invisible flame that emits no visible smoke, traditional sensors fail to see it. The Flame 1750 utilizes three distinct infrared (IR) spectral bands to recognize the unique water vapor signature produced by hydrogen combustion from long distances.

Advanced Multi-Wavelength Fire Discrimination

Operating in high-risk green energy, chemical, or manufacturing plants demands extreme precision. This triple-IR sensor configuration provides localized safety and unmatched hazard evaluation:

• Hydrogen-Specific IR Spectrum: Tunes its active optical paths to catch the exact infrared emissions of hydrogen fires while ignoring deceptive industrial background noise.

• Extreme False Alarm Immunity: Advanced mathematical algorithms fully filter out interference from arc welding, hot processes, x-rays, and intense direct sunlight.

Key Features and Industrial Benefits

• Rapid Speed of Response: Detects sudden hydrogen gas ignitions within a fraction of a second, immediately triggering automated ventilation and safety shutdown loops.

• Extended Coverage Range: Capable of detecting a standard 0.6-meter (2-foot) hydrogen plume fire at distances up to 40 meters to optimize facility safety layouts.

• Automated Optics Diagnostics: Built-in optical integrity test (BIT) automatically monitors the cleanliness of the sapphire window and internal circuitry to minimize manual field checks.

• Rugged Marine-Grade Housing: Encased in an explosion-proof, IP66/67 rated 316 stainless steel enclosure built to survive harsh marine, offshore, and clean-energy infrastructure environments.
