Dräger Flame 2350

​Working in areas with combustible gases, vapors, or materials requires fire/flame detection as a life-saving necessity. The best solutions must combine state-of-the-art technology with rugged durability and be ready to reliably work in any situation. The Drager Flame 2350 is a dual spectrum optical detector, using a combination of ultra-violet and infrared sensors to detect fires at a high speed response time of 200 milliseconds.

A Multi-Talent with more features

​The Dräger Flame 2350 combines UV and IR sensors that are capable of detecting hydrocarbon-based fuel and gas fires.

Performance you can trust

​The Flame 2350 senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are then analysed for frequency, intensity, and duration. The simultaneous detection of radiant energy in both the UV and IR sensors then triggers the alarm.

Robust and intelligent

​The flame detector is designed to cope with harsh weather conditions. It comes with features such as a heated window against snow, ice, and condensation and a rugged outer housing. At the same time, models are compact and lightweight, making them ideal for any situation or installation set-up.


​Functional safety is a concept applicable across all industry sectors. It is fundamental to enabling complex technology and provides assurance that the safety-related systems will offer necessary risk reduction. The Flame 2350 is highly reliable and complies with the IEC 61508 Safety Integrity Requirements of SIL2.

Automatic and manual optics checks (BIT)

​Automatic checks of the detector electronics and optics helps ensure that no fault goes undetected. Additionally, the test can be triggered manually at any time.

Easily visible status LED

​A tri-colored LED on the front of the detector provides a simple status indication to personnel in close proximity. Green indicates normal operation, yellow indicates a fault, and red indicates the presence of radiation from a fire.

Simple installation and commissioning

​Installation is simple! The detector is easily installed with a stainless steel tilt mount, enabling the detector to be rotated up to 60 degrees in all directions. This offers flexibility in positioning the detector in relation to potential fire sources.
