For small and medium-sized pieces and weight not superior to 5000 kg, can be used washing booths with rotating platform. The platform is made rotate by a special hydrodynamic nozzle or electromechanically.

The tanks under the workplan are provided with large windows of cleaning and inspection. Solutions are supplied from the reservoirs through one or more electro-pumps and the solutions made circulate return to the reservoirs through removable metal filters that make it possible to clean them.

In Sprymaster TR Tau series an exclusive original system of valves, assisted by pneumatic actuators, limits the well-known negative effects caused by the solution mixing in cycle in the washing chamber.
