搜索结果：SFDS

The SFDS is a system designed for reliable monitoring of smoldering fires by detecting carbon monoxide CO and oxygen O2 in high dust environments. It provides early detection of fires, even in deep-seated embers, unlike optical systems. Certified for use in ATEX zones 20, 21, and 22, it is ideal for dust-heavy areas such as coil mills. The system monitors up to four sampling points simultaneously, ensuring timely fire prevention measures in hazardous conditions.
