HV Series Blast Damper is designed to protect personnel and critical equipment against blast wave created by explosion in industrial facility. Gas explosions occur in facilities such as Oil&Gas platforms and refineries.
The product is used in ventilation systems to prevent advance of the blast wave, through external walls, into the building. Force of the wave closes blades and seals the building. Protected spaces can be such as control rooms, instrumentation rooms, electrical sub-stations, personnel spaces and emergency shelters.
High performance blast protection allows flexibility in plant layout design and makes lower acceptable risk level possible.
