Why Controlled Rotation Makes a Difference in Sewer Cleaning
Successful sewer cleaning is not just about using the highest possible pressure. In many applications, precision, control, and the right water flow are just as important—especially before CCTV inspections, rehabilitation work, or when cleaning different pipe diameters.
The DUEBRE BLUE Series was developed specifically for these requirements. Its slow-rotating, magnetically controlled technology sets it apart from conventional rotating nozzles, delivering controlled cleaning while maintaining excellent pulling power.
Controlled Rotation Instead of Free Spinning
The key feature of the BLUE Series is its electromagnetically controlled rotation speed. Unlike conventional rotating nozzles that spin freely, the BLUE nozzles regulate and slow down the rotation for greater control.
This provides several practical advantages:
- Better control during cleaning
- More consistent cleaning results
- Ideal for preparing pipes for CCTV inspections
- Well suited for rehabilitation and repair work
Because the braking system operates without physical contact, there is virtually no wear on the speed control system.
High Cleaning Performance at Lower Pressure
A common misconception is that higher pressure automatically means better cleaning.
Thanks to its hydromechanically optimized design, the BLUE Series often achieves excellent cleaning results with just 60 to 100 bar. At the same time, the nozzles generate strong pulling power and move reliably through the pipe.
Operating at lower pressure can also provide additional benefits:
- Reduced load on the pump and engine
- Lower fuel consumption
- Less wear on equipment
One Nozzle for Multiple Applications
The BLUE 100 Transformer is particularly versatile.
With a range of optional attachments, the base nozzle can be adapted quickly for different cleaning tasks. Depending on the application, it can be converted into, for example:
This allows a single base nozzle to handle a wide variety of cleaning applications.
Easy to Adapt to Different Equipment
The thrust inserts can also be changed within seconds.
This allows the nozzle to be quickly adjusted to different vehicles, pump capacities, and pipe diameters—without complicated modifications.
Designed for Fresh and Recycled Water
The BLUE Series is designed to operate with both fresh water and recycled water.
High-quality ceramic inserts ensure reliable performance even when using treated or contaminated water. At the same time, the nozzle orifices maintain their dimensions over long periods, helping reduce maintenance requirements and wear.
