The planet wheel washing unit is equipped with 3 brushes instead of a circular broom.

The wheel washing units can be additionally equipped with a height adjustment mechanism.

The wheel wells and sills of the vehicle are cleaned by water jets from 2 additional nozzles per washing direction.

The vehicle underside can be washed with the underbody washing unit. For this, water is sprayed at high pressure over the entire underbody via two pivoting nozzle pipes.

Foam is applied to the front half of the vehicle by the prespraying nozzles. The foam is generated from water, prespraying agent and compressed air.

Pre-cleaning chemicals are applied to the vehicle by stationary nozzles.

The foam is generated from water, prespraying agent and compressed air.

Compressed air is used to spray a water-cleaning agent mixture onto the wheel rims via 2 stationary foam nozzles.

The high-pressure wash removes coarse dirt from the surface of the vehicle. High-pressure cleaning minimises the danger of scratching from sand grains or similar abrasives and makes a significant contribution to preserving the paintwork during cleaning.

Various different versions are available:

• Working pressure 16 bar (1.6 MPa)

• Working pressure 60 bar (6 MPa)

• Working pressure 70 bar (7 MPa), on-board high-pressure pump (in the portal)

The cleaning agent heater is located in the cleaning agent supply in pillar 2.

The washing bay can be equipped with a frost protection device:

If there is a danger of frost, the water is blown out of the piping system automatically.

This blowing process is controlled by a thermostat.

Demineralised water (from an on-site system or optionally available reverse osmosis system) or fresh water dosed with drying aid is sprayed onto the vehicle via the drying aid nozzles.

A compressed air foamed mixture of water and cleaning agent is sprayed onto the vehicle via 2 stationary nozzles. This is followed by a polishing procedure with the washing brushes.

Safety switches are required if the required safety clearances between the washing bay and permanent fixtures (e.g. walls, pillars, sinks) cannot be maintained. The safety switches prevent persons from being crushed between the system and the wall.

The washing bay stops immediately if a safety switch touches an obstacle.

The splash guard protects the areas adjacent to the washing station from sprayed dirt and splash water emitted by the rotating side brushes.

The splash guard is attached to the outer surfaces of the chassis and suspension as well as the pillars.

The purpose of the bollard protection is to ensure central alignment of the vehicle. They prevent the vehicle from being parked too far away from the centre.

The Reset function allows the wash gantry to be moved to the iniial position remotely with a command via an interface. The function can be enabled via a separate parameter in the system control.

• This function must only be enabled in countries or at locations where this function is permitted.

• Video surveillance must be installed on site, covering the entire area of the washing hall or the entire travel path of the system, and any regulations applicable in the country/municipality where the system is installed must be applied.

• The person who performs the remote reset must first ensure via the video surveillance that there are no persons in the travel path of the system. If a person then requests the command, that person must confirm that the system and its travel path are completely free by acknowledging a safety notice (e.g. pop-up window).

• The person who integrates the system into his system, e.g. via the Internet, is responsible for the required security or cybersecurity and a risk assessment must be carried out on the system.
