Let Robots Go In - So People Can Come Home

Yes. Our process follows a strict No-Man Entry policy. The operator remains safely in the Zone-1 control unit and monitors the robot through multiple ATEX Zone-0 cameras, while a small crew (typically 2 people) manages external hose handling with our winder systems. No one enters the tank at any stage. The complete setup—from arrival to robot deployment—typically takes about four hours.

The N-MER comes with a custom-designed high-pressure Rotary Surface Cleaner, High-pressure water jetting nozzles and expandable wipers that effectively cleans the bottom plate.

Yes. The robot is designed to move around tank legs and obstructions smoothly. With ATEX Zone-0 certified forward, rear, and global-view cameras, the operator can clearly see all obstacles. Unibose’s planned cleaning methodology ensures controlled navigation and prevents the robot from getting stuck inside the tank.

The robot operates with hydraulic power and can function even when completely submerged in sludge. The ATEX cameras can rise up to a maximum height of 1.2 meters and come equipped with Self Cleaning Spraying System to clean their lenses in case of dirt buildup.

Our state-of-the-art robots possess a remarkable sludge cutting system at the front, capable of breaking down even the densest sludge without the aid of water. This innovative feature not only reduces waste but also demonstrates our commitment to environmental sustainability.

No. N-MER is a fully self-contained system. It requires no scaffolding, and because the process is entirely unmanned, no rescue or standby teams are needed.

Unibose’s N-MER is built with a first-of-its-kind Emergency Evacuation equipped crawler System designed specifically for confined-space environments. If a fault occurs during operation, the robot can be safely retrieved from inside the tank within minutes—without any human entry. The unit is then serviced immediately on-site and relaunched to resume cleaning with minimal downtime. This ensures uninterrupted operations and maintains No-Man-Entry compliance under all times.

No. In practice, N-MER is proven to reduce overall tank-cleaning time by up to 40%, which directly improves production uptime and lowers total cost. With 45% reduced OPEX, fewer man-hours, and no need for rescue teams, tank spading, or additional permits, the robotic method becomes significantly more economical. As the operation involves zero human entry, we fall under a medium-risk classification, simplifying paperwork and further reducing cost and delays.
