Europäische Brandschutzklappen CE-Norm EN 15650
Serie WH45P

Overview

Fire dampers Series WH45P ensure maximum safety in the prevention of the spread of fires within the buildings. Indeed they guarantee the perfect heat insulation and complete seal is to hot to cold smoke fumes as demonstrated by the numerous tests performed according to standard EN 1366-2.
Fire dampers WH45P series are characterized by the highest performance, up to EI 180 S, and particularly for the possibility of installation method "Wechschott" into large openings with sealing in high density rock wool and coating with endothermic coat.

By connecting the dampers to the fire alarm system and smoke detectors can anticipate the closing of the blade compared to the direct action of the flame and thus preventing the onset of indirect damage arising from the spread of smoke and gases generated by combustion.
