A new under-chassis wash spray system has been launched by Smith Bros & Webb, the commercial vehicle automated washing systems maker.

The company has totally re-designed its original Chassis Master machine to produce the fully-MOT-compliant new Chassis Master which offers both lower operating costs and increased reliability. It no longer needs hot water or chemicals and it is easy to operate and has also been resigned to have less maintenance costs.

The new machine features a twin shaft high pressure plunger pump (dual) operating at up to 45 bar pressure at the jets. The running frame is hot-dip galvanised steel and has been re-designed to drive without the use of cable drums or being pulled under its own services.

It is housed in a stainless steel enclosure which can accommodate different vehicle sizes and can be constructed to a customer's requirements in varying lengths, starting from a 12-metre wash track, then extending to 15 metres, 18 metres and upwards in steps of 3 metres. The control panel can identify vehicle length.

A typical wash cycle is 20 minutes.  High energy cold water is directed on the chassis by the swinging arm and oscillating nozzle head. Nozzle angles are designed to ensure effective coverage of the chassis. At the end of each cycle the Chassis Master self-cleans on the return back to the homing position.

Andy Barracliffe, director of Smith Bros & Webb, said: 'Our new Britannia Chassis Master surpasses all other products in the market and is truly best in class.

'We have listened to our customers and incorporated features in the new Chassis Master that we are confident will exceed all expectations. The fact that we have improved efficiency, lowered operating costs and reduced maintenance requirements while still offering exceptional wash performance makes it a compelling proposition'
