Firefly AB sets new standards24 October 2014
Firefly AB, is claimed to be the first company in the world, to be FM approved for spark detection/extinguishing system with spark detectors detecting hot particles down to ≥250°C (≥482 °F) and for spark detectors detecting down to ≥400°C (≥752 °F) where the symbol ≥ expresses ‘greater than or equal to’.
Firefly AB has always been known for its advanced detection technology with high performance detection of hot black particles, glowing embers and sparks as well as the detectors being insensitive to daylight. Firefly has had several other third party approvals but this is the first time the detection temperature has been approved.
Detecting down to 400°C or 250°C is critical to prevent fires and dust explosions based on the minimum ignition temperature (MIT) and minimum ignition energy (MIE) for most process material.
