For cleaning water reservoirs and water towers

Traditional cleaning processes meant that water towers and drinking-water reservoirs had to be emptied and manually cleaned or divers sent down. In both options, the reservoir has to be taken offline, which can lead to major disruptions in the main supply system. Emptying a reservoir is time consuming and cleaning is labor intensive. Sending divers down in drinking water also entails a risk for contaminating the water. When the robot was developed the ambition was to design a vehicle that could clean effectively without having to shut down the reservoir and without sending personnel down into the reservoir.

The robot is remote controlled and equipped with rotating brushes and a powerful pump that directly pumps out all loosened sediment without raising turbidity in the reservoir. It is equipped with a video camera that facilitates inspection of the inside of the reservoir. The entire cleaning process is documented and the customer receives both a videotape and a written report.

Specifications: Dimensions (L x W x H): 735 x 595 x 400 mm Pump capacity: 70 m3/h Speed: Variable from 0.5 to 10 m/min depending on sediment depth. Power consumption: 2.3 kW Other: Pan and tilt high-resolution video camera. Remote operation with variable brush speeds

Wall cleaning under water

The Robot has in this special application been specifically designed so that it floats when dropped into the tank. When the pump is started the cleaner moves automatically to one of the walls in the tank and sucks itself onto the wall. It may then be remotely driven along the entire wall. In this application down to 5- 6 meters depth. When the first wall is cleaned the pump is stopped which makes the cleaner float to the surface and is now ready to be steered onto the next wall.

Specifications: Dimensions: (L x W x H) 860 x 600 x 300 mm Weight: approx. 52 kg Weight in water: approx. 7 kg Suction width: 600 mm Suction capacity: 1200 lit/min Speed: 0,2 and 0,4 (travel) m/s
