Firefly, Stockholm, Sweden, reports that it has recently received an FM-approval towards the new FM standard 3265 covering its spark detection and extinguishing systems. The FM approval covers over 70 detectors and all detectors are also available in versions for use in explosive atmospheres, Ex zone 20, 21 or 22.

 

Firefly’s state of the art, True-IR detectors, are specially designed for detection of all types of ignition sources such as sparks, flames and hot (black) particles. All Firefly spark detectors works in the True-IR spectral range, which enables detection down to the minimum ignition temperature (MIT) and minimum ignition energy (MIE) of the material and are at the same time insensitive to daylight. Being insensitive to daylight is essential to avoid false positives and avoid unnecessary and costly interruption of the process. This will also make it possible to install the detectors in an area where daylight is present. The Firefly spark detection system offers advanced detection functionality which is said to be unrivalled on the market. www.firefly.se
