The Drager Flame 1750 H2 uses a triple IR sensor to detect hydrogen-based fires, which is highly reliable against false alarms. It maintains good measurement performance even at extreme temperatures.
Fast and safe detection
The Drager Flame 1750 H2 is a certified hydrogen fire detector that can detect 1-meter flames at up to 40 meters distance in just 5 seconds, meeting IEC 61508 requirements for safety integrity according to SIL 2. The flame detector also has HART and RS-485 interfaces and has low energy consumption.
Developed for hydrogen
The Dräger Flame 1750 H2 was specially developed to detect hydrogen fires. Its three IR sensors measure only in the 2 to 4 μm range relevant to hydrogen flames, guaranteeing high performance and a low false alarm rate. Common sources of false alarms, such as hot CO2 or welding work, are no longer a problem.
Robust and durable
The housing is very robust and weatherproof. To protect against icing and fogging, the window can be heated automatically. This allows you to operate the Flame 1750 H2 reliably even under extreme environmental conditions, e.g., temperatures from -60 °C to +85 °C.
The built-in self-test “Advanced Optical Verification” (AOV) automatically checks the electronics and optics of the Flame 1750 H2. The front’s three-colour LED lets you see the device status quickly. Green stands for normal operation, yellow indicates an error and red signals a fire alarm.
