3L Leak Control Safety Pipe System

Permanently or intermittend monitored piping system that finds and reports damages

The 3L Leak Control safety pipe system provides a 100% leakage monitoring for soil and water protection.  It has been designed to report and locate damages – even on a mains-independent basis – and can be accessed and controlled in real time via the internet. A monitoring unit conntected to the pipe emits an alarm even by the smallest damage to the pipe. Messages will be sent directly to the control centre or to the smartphone. It can automatically switch off connected pump systems, thus preventing disasters reliably and at an early stage.
