3L Leak Control

Permanently or intermittend monitored piping system that finds and reports damages

Brief description

The 3L 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.

Product Benefits | Product Structure

  • Permanent Monitoring of the Pipeline, exact detection of leakages
  • Remote maintenance for the installed pipe as well as all installed system parts
  • Intermittend Monitoring in areas without any electricity supply is possible via a battery-powered monitoring unit
  • Cost-saving compared to conventional double containment systems
  • A piping system for open and closed constructions (both for new constructions and rehabilitations)
  • Safe welding Connections according to DVS 2207
  • Fulfils the requirements of continuous leakage Monitoring according to ATV-DVWK-A 142 for use in potable water protection Zone II with high risk potential
