The tunnel car wash systems with brushes are provided with a revolutionary geometry: the horizontal and
vertical brushes make possible to carry out an intervention on the vehicle for a longer time and with a
longer intensity compared to the portal groups with traditional brushes.
The fundamental difference from gantry washing is the fact that it is not the device that moves but the car,
which is driven in the different steps by the washing chain:
- pre-wash with shampoo arch
- washing with anti-scratch brushes
- underbody washing and wheels washing
- high pressure washing and robowash
- wax with osmosis water
- drying
- polishing
This makes it possible to maintain a higher advancement speed of the conveyor chain, ensuring a
considerable number of vehicles treated: this type of structure is in fact suitable for washing a large
number of vehicles.
