WarnEx - smouldering detection system

 

Description


Smouldering is one of the most common ignition sources of fires and dust explosions in industrial processes. Unfortunately it is also one of the most difficult to prevent by controlling process conditions or by making modifications to the equipment. The Fike WarnEx™ system will detect and signal smouldering at an early stage before damage to the process equipment has occurred. The alarm signals can be used to trigger safety systems, such as operator intervention, process shutdown or water injection.
The WarnEx™ system typically consists of multiple ‘Sampling and Detection Units’ (SDU’s) placed on each air inlet and outlet. CO gas, created by smouldering, will be detected by the WarnEx™ SDU placed on the main air outlet of the process. In order to filter out nuisance CO entering the system from the outside, additional SDU’s are placed on each air inlet. The WarnEx™ Control Unit processes the signals from the SDU’s and alerts the process operators and safety systems in case smouldering material is present.
