Plant Engineering » Tank cleaning by close loop system


Tank interior cleaning equipment for tank and container cleaning in close loop system. Cleaning of hard-to clean materials like:

Latex, Acronal, Primal, and much more, means  „long“ cleaning time. Hier besteht die Aufgabe in Ressourcen schützen und Reinigungsprozesse zu automatisieren.

WEIDNER Tank interior cleaning by close loop system is designed exactly for this hard operation, developed and built. The safety of the operator is our top priority. No entry into the tank is more needed and after the expiration of its  freely adjustable cleaning time the system switches off and ensures you a high profit while protecting the environment.
