Smoldering Fire detection with SILOTEC

Smoldering fire detection with the Silotec from Enotec

Before starting a fire that may trigger a fire detection, it is better to detect smoldering fire. The Enotec Silotec has been specially developed for measuring in a coal silo. This is due to the danger of smoldering, which can cause a fire. However, there are other applications where a flammable situation could arise in a silo. A Silotec from Enotec measures the most important component for smoldering, CO. The second most important gas molecule is O2 because it gives an indication of the inert conditions in a silo. This is always related to CO when there is a fire. So, O2 and CO are measured simultaneously, and smoldering fire can be detected with the Silotec. the efficiency of the inertization can also be monitored. The Silotec complies with Atex zone 20. The system has a fast response time to be able to respond in time if danger threatens.
