EWS ALF Series — ultra-sensitive spark detection and precision water extinguishing. Protecting your plant, your people, and your production from fire and explosion risk.
EWS ALF Series — ultra-sensitive spark detection and precision water extinguishing. Protecting your plant, your people, and your production from fire and explosion risk.
In pneumatic conveying systems, blow pipes, chutes, dust filters, silos, and bins — sparks and glowing particles are a constant risk in panel, wood-processing, and bulk-material industries.
A single fire event can cause production stoppage, equipment damage, and in the worst cases, loss of life. The cost of prevention is a fraction of the cost of a single incident.
Developed from decades of field experience and extensive wind-tunnel testing at air velocities up to 36 m/s.
