NESL Solution
"Tailored Solutions" — based on different tank conditions, we provide different equipment and cleaning plans to address issues in a targeted manner.
High-definition cameras enable full-process visualization and real-time data recording, eliminating blind cleaning, enhancing effective cleaning, and reducing waste of resources and energy consumption.
The system is installed via the tank manway, connected with hoses and hydraulically driven. The manway cleaning method eliminates the need for climbing and excessive lifting operations. Direct hose connections — instead of rigid pipe installation — reduce leakage risks and handling intensity.
The Manway Cannon high-pressure manway cleaning system is developed to eliminate the need for personnel to risk entering tank bodies for cleaning. It can clean large storage tanks with a maximum diameter of up to 100 meters. The system adopts all skid-mounted modules, which facilitates the entire installation and transportation process while reducing the risks associated with installation.
