With the new CB-series Kärcher has launched gantry car washes that have a proper style and therefore give a professional impression of the operator. The modern design provides us with an attractive overall picture. Due to the LED traffic-light and the information about the single washing phases the client receives clear information. The switchboard and the boxes for the cleaning agents are stationed in the portal. The pillars are accessible by three sides which enables to offer a better service; the technique is simple, robust and reliable. The drive, the linings and guides which are all low-maintenance, do not need any oil, grease or cleaning-spray. All pieces of steel are hot dip galvanised and protected by a powder coating. Doors, covers and guide rails are made of high-quality plastic or stainless steel.
