Heavy vehicle wash machines

The Heaviest Cleanliness

A clean vehicle is your company’s most visible business card, whether it’s a truck, bus, tanker or garbage truck. From us, you get real heavy-duty expertise for washing heavy equipment.

A dirty vehicle may have collected a lot of sand and other dirt, so it also consumes more fuel. Our heavy equipment washing equipment cleans vehicles of all shapes and sizes, even very dirty ones.

Investing an automatic washing machine pays for itself quickly!

Clean equipment easily and cost-effectively

It is not worth spending work time on washing heavy equipment by hand, when our advanced washing machines do it efficiently, safely and reliably using automation.

We get to know your needs and look for the best, individual washing solutions together. We deliver, install and test the washing system for operational condition, and we also guide you in choosing chemicals.

High-pressure wash as the main factor

High pressure significantly affects the wash result. The water jet also reaches the areas which the brushes cannot reach, and especially the oscillating zero-degree nozzles remove even thick layers of dirt.

Comprehensive double coverage sweeping

The side jets clean the sides of the vehicle from sill to roof. Pivoting side arch and together with the oscillating nozzle movements effectively direct the pressurised water jets into crevices and depressions.

Vertical front contour tilting brush action

Brush pneumatic inclination instead of the traditional power push and tilt method, following the shape of the front, gives excellent wash result for the entire surface without endangering the vehicle’s large windshields.

Enhanced washing of hems and wheels

The hem nozzles can be activated both brushless and brush wash, from the front to the rear.

Powerful chassis wash

Chassis wash can be activated both brushless and brush wash when the vehicle drives over the spray head.

Wide range of options

There are several different washing functions to choose from and ways to follow the shape of the vehicle, such as the mirror bypass function.

RAINBOW ULTIMA automatic wash machines

Rainbow Ultima is the most advanced and efficient automatic washing equipment for heavy vehicles with a very wide range of applications. The most typical vehicles which are washed with Ultima are trucks and buses.

Ultima wash machines can be equipped with two or three brushes, with side and top high pressure. These wash machines are available as roll-over and drive-through machines with floor or wall mounted running tracks, depending on the model. Thanks to advanced automation systems, all types of vehicles can be cleaned efficiently.

In roll-over machines, the vehicle remains stationary throughout the wash. In drive-through the front part is washed first (stationary), then the driver moves the vehicle for wash of the sides and at last stays put for the wash of the rear.

Brushless wash power is needed for washing tankers, fire trucks, concrete and waste transportation trucks, and this especially the Rainbow Ultima Spinner offers.

Alternatives for high-pressure washing are oscillating zero-degree nozzle, rotating Spinner nozzle and v-spray nozzle equipment.

The equipment to be washed and the size of the wash bay largely determine what kind of washing machine and with which options is the most suitable package for the customer.
