NIMU is a reusable, non-invasive detection system. After an overpressure event, and the associated opening of the rupture disc, the outlet part of the rupture disc holder must be removed, the rupture disc replaced, and afterwards the system can be put back into operation. The days when the signalling cables also had to be routed again to the respective switching box are finally over.
Additionally: The process is absolutely leak-tight. The blind tapping in the holder replaces the tapping which is usually required. The absence of cable glands (required for the holder tappings for conventional signalling cables) means that the cable glands used cannot become porous, thus preventing an escape of the process media.
Advantages
• Totally leak tight process.
• Cost-effective signalling device.
• Full bore relief.
• Easy function testing and maintenance.
• Eliminates false alarms.
• Reusable.
