DUNOS-R surge cleaner

Flexible installation, thorough cleaning

The Guth DUNOS-R cleaners set new standards in the purity of containers and tanks. The self-cleaning surge cleaners show their full strength with sensitive components in particular, such as membranes and compensators. They are  designed as an internal cleaning nozzle with a rotating spray body.

Where high pressures and punctual force effects are not permitted, the cleaners of the DUNOSR series ensure uninterrupted cleanliness. The fast-rotating nozzle wets the surface evenly and is suitable even for extremely aggressive, pitting corrosion causing media.

Confirmed by 1000 hours stress test

The actuator of the  DUNOS surge cleanerR is via the cleaning medium, which is quickly and economically distributed in the container. The rotation of this self-cleaning sanitary fitting ensures a comprehensive wetting of any container. The liquid storage ensures excellent stability and freedom from particles.

Ideal for direct use: Our predefined cleaning patterns are adapted to the most common coverings and tank types. For individual cleaning, the jet patterns can be adapted to the respective contamination and container geometry.
