High-pressure pre washing arch
Especially dirty vehicles can be pre-washed with high pressure. The automatic wash cycle is monitored by a light barrier on the gantry (also required); manual setting via the control panel is possible. The pre-rinse and high-pressure pre-wash programmes can be started individually, in combination with one another, or with a brush wash programme. The tube bend is installed on the front of the brushes on the gantry. It is equipped with fan jet nozzles for an especially thorough pre-wash. The high-pressure bend is supplied via it's own hose system. A pump module that provides for the water feed can also actuate the underbody washing system (see below). In this case an additional solenoid valve is required for actuating it.
