Enz camera nozzle

In order to ensure the trouble-free functioning of sewer systems in municipalities or industrial plants, they must be cleaned regularly. This is typically done by a water nozzle operated with high pressure. The cleaning result is usually not completely checked visually, because the effort for an inspection with an inspection camera is too high.

Our customer enz® is a leader in water-driven cleaning tools up to 3'000 bar. These hydrodynamic and hydromechanical cleaning tools are used to clean surfaces as well as pipes and channels.

To document the quality of a cleaning economically, enz® has developed a camera system together with Helbling that can be integrated into various cleaning systems. In this way, videos are recorded directly in parallel with the sewer cleaning and automatically stored in a cloud via a smartphone. Cleaning companies and clients can access the data after completion of the cleaning process and from any location and assess the cleaning result or detect any damage in the sewer.

Helbling has developed the «seeing nozzle» as a system together with enz® up to production readiness. The system, which is integrated into a compact housing, consists of a camera with an illumination system and on-board power supply, image processing, and buffer memory. This hardware can be integrated into several enz® cleaning tools. Furthermore, the system includes a wireless charging station, a smartphone app and the cloud environment for remote access to the recorded data.
