Field of application
The SFDS is a continuous measurement analyzer system for monitoring carbon monoxide and oxygen in applications with high dust content. The extractive measurement of the components CO and O2 enables early detection of smoldering fires and timely initiation of fire-fighting measures. The ATEX-certified system components allow for reliable monitoring in dust Ex areas (ATEX zones 20, 21 and 22). Unlike with optical systems that measure the surface, deeper-lying embers can also be detected.

Early detection of smoldering fires

Device properties:

Early CO detection through continuous monitoring

Application-specific gas sampling with integrated backflush

Measurement point switchover for up to four sampling points

Gas sampling using heated sample gas line for ATEX zones 21/22, gas sampling unit for zones 20/21/22

Setup of analyzer cabinet in Ex-free areas

Pre-configured complete system for easy commissioning

Benefits
Risk minimization thanks to early detection of smoldering fires – protects your capital equipment

Long system uptime thanks to high gas sampling quality due to integrated backflush

Uninterrupted gas sampling possible in ATEX zones 20, 21 and 22

Low operating costs due to long service and test gas intervals and low consumption

Cost efficient with only one analyzer for up to four sampling points

Industry-proven S700 analyzers are the heart of the system.
