Improved car wash installation and corresponding process for washing

An improved car wash installation comprising:a first gantry (1) fitted with:systems (3) for spraying a pre-washing liquid such as an emollient;means (5) which move along vertical guides (4) and which are designed to scan the contours of a vehicle;drying devices (7,8) designed to direct jets of pressurised air laterally and downwards onto the vehicle, anda second gantry (2) to fitted with:a vertical brush unit (14) associated with means (16) for spraying high-pressure jets of water which are located on both sides of the gantry;a horizontal brush unit (18) associated with means (16) designed to spray water at high pressure onto the vehicle; wherein said means (16) designed to spray water at high pressure are installed immediately upstream of the corresponding brushes (14,18) so that they engage the vehicle first during the forward pass of the gantry (2).This characteristic makes the washing cycle much shorter than those of known car washes, because the entire car washing and drying cycle can be performed with a single forward and reverse pass of the two gantries (1,2).
