WNV-systems three brush roll-over


The three brush wash machine is the preference for the cleaning of conventional road going commercial vehicles. This equipment is designed to wash vehicles quickly and effectively ranging from small vans to large articulated units and trailers.


WNV-systems 5.0m Commercial three brush wash machine including the following features and components:


3 brush operation for the washing of vehicle front, rear, sides and roof

Automatic vehicle height and length detection

5.0m maximum vehicle wash height suitable for double deck trailers

Fast and effective single wash cycle to suit the all vehicle types

Automatic articulated vehicle gap avoidance

Automatic forward facing cab mirror avoidance

Automatic emergency fifth wheel avoidance

Galvanised steel machine frame

Microprocessor / PLC control panel

Variable speed, soft start gantry drive motors providing fast wash times with extended motor and gearbox life

On-board spray suppression screens to contain spray within the wash bay

Cleaning is achieved by applying a diluted detergent solution directly to the exterior of the vehicle while simultaneously scrubbing with rotating brushes. This process is then repeated, without detergent to rinse the vehicle clean.



The machine frame is a mild steel box section fabrication, which is hot dip galvanised to prevent corrosion. PVC spray screens surround the frame to contain water and chemical spray to a minimum. Low-density polyethylene brushes are used for both the horizontal and vertical brush shafts. Geared electric motor units drive movement of the brushes and gantry travel. All motors are protected to a level of IP6.6 from the ingress of water and all gear units are lifetime sealed with a fully synthetic lubricant to maximise service life. The electrical panel is controlled by a Microprocessor, which computes signals given from positional detectors and brush pressure sensors to precisely follow vehicle contours. All user controls are twenty four volts for user safety. A safety cut out is incorporated, this will sense a motor or top brush pressure overload, and stop the machine in the event of a problem. An indicator mounted on the control panel and will then show the type of fault that has occurred. The side brushes are pneumatically controlled to keep a constant balanced pressure on vehicle sides.
