NIMU (Non-Invasive Monitoring Unit) is a reusable monitoring system, which informs the operator as soon as the rupture disc responds to an overpressure or vacuum situation.
The unit is installed in a blind tapping in the outlet section of the rupture disc holder. This completely isolates NIMU from the process and prevents potential leakages.
After a rupture disc has opened, only the rupture disc itself must be replaced. This reduces production downtime and associated costs to a minimum. NIMU is based on tried and tested, intrinsically safe, closed circuit technology and is therefore easy to integrate into process control systems.
