Scanjet model SC 20A HP (high pressure) is a tank cleaning machine especially developed for cleaning silos, tanks in industrial applications and other applicable tanks, this model is also available in a LP (low pressure) variation. The size, construction and cleaning requirements of these tanks are design criteria for the tank cleaning machine, which have been evaluated prior to installation in your application.

SC 20A HP/LP tank cleaning machine consists of a gun unit that is installed in the tank and an air driven drive unit. The cleaning procedure will start by opening the valve for the cleaning media and the valve for air supply to the drive unit. The drive unit will then rotate the bottom housing, also forcing the nozzle housing to rotate around its own axis because of the gear system. This creates a criss-cross cleaning pattern on the tank walls. When the cleaning procedure is finalised the valves are to be closed.
