Triple Infrared Hydrogen Detection

FlameSpec-IR3–H2 is the next generation of the IR3. It is  introduced to further enhance the protection and safety of those high risk and high value industries. The FlameSpec-IR3-H2 will detect hydrogen fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimizing the consequences! The unmatched detection times and distances are:

• Detection within 40 milliseconds of fireballs or explosions 
• 1.5s for 0.8m hydrogen fire at 0–20m
• 4s for 0.8m hydrogen fire at 20–30m

The FlameSpec-IR3-H2 flame detector provides ultra-fast response, high performance, and reliable detection of hydrogen fires. It operates in all weather and light conditions with the highest immunity to false alarms. These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews​.

FlameSpec-IR3–H2-HD has the addition of Integral HD quality video, with event recording, on top of the proven, superior capabilities of Triple IR (IR3) flame detection, providing a very powerful safety tool to protect personnel, plants, and processes. The detector's high-definition (HD) video output provides visualization of hydrogen flames that are invisible to the human eye. This allows the rescue team to be aware of the exact situation and location of invisible hydrogen flames before entering the hazardous area. The detector automatically records video of any fire event (1 minute pre- and up to 3 minutes post alarm initiation). These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews 

Key Benefits:

FlameSpec-IR3-H2 and IR3-H2-HD:

• Extreme sensitivity - up to 30m for a 32 inch Hydrogen Plume flame.  
• Ultra-fast detection mode - detection within 40 milliseconds for Hydrogen fireballs or explosions Hydrogen flame detection.  

• 1.5 second detection time - for 0.8m hydrogen plume fire at up to 20m distance.

• Data/Event logger - alarms, faults and other relevant events are logged to non-volatile memory.  
• Built-in-Test (BIT) - Automatic and manual self-test of window cleanliness and the overall operation of the detector.  
• Window heater to avoid condensation and icing.  
• Tilt mounting bracket can be connected either above or below the detector.  
• High immunity to false alarm.

FlameSpec-IR3–H2-HD only:

• HD video output with Automatic HD video recording of fire events. Visualization of hydrocarbon flames that are invisible to the human eye.  
• Ethernet communication – in addition to the standard methods, such as Relays, 4-20mA and Modbus.
