Wheel washer FAQ

What’s the best choice?

Though a roll-type wheel washer achieves the best cleaning result, they have far higher maintenance costs and the washing time takes far longer. When traffic rates are high a roll-type is no option. Only when the situation leaves us no other choice – for example when there no space to put any other installation – we would advise a roll type wheel washer.

What about roll type or drive-through type?

Roll-type wheel washer have the principle of a rolling axle with a pedal switch which cleans the wheels whilst standing still. Multiple wheel rotations are made before the roller axle stops and the truck can drive further.

Drive-through type wheel washer work inverse. Wheels are cleaned whilst driving over a steel structure with nozzles in it. The heavier the contamination, the more wheel rotations are needing and thus the longer the wheel washer needs to be.

What is the ideal pressure for a wheel washer?

Wheel washing systems use low pressure starting from 1,5 bar to 4 bar and flow rates from 1.000 l/min up to 9.600 l/min. Cuypers NV opinions to use higher pressure rates as it will reduce cleaning time. This is possible because we can offer different systems which clean the water. For compact units we have an unique stainless steel filter screen which blocks all particles > 1 mm. For large units we have a compact water clarifier which clears water up to 10 NTU. For special installations – and only in combination with a water clarifier – we also offer pumps with a pressure up to 6 bars. Generally speaking we offer higher pressure pumps for sticky conditions and high flow pumps for conditions with great amounts of dirt.

What’s the best wheel washer for my personal situation?

Two main factors play a role when choosing the right wheel washer: type of pollution and traffic rate. Cuypers NV offers a variety of options to deal with these factors. Wheel washer lengths from 2,2 meter up 12 meter and a wide range of pumps. Built-in or top surface. When there are + 100 trucks/day we also offer a GWC water clarifier which ensures clear water regardless of traffic.

What are the advantages and disadvantages of a water clarifier?

A water clarifier becomes interesting a traffic rates of over 100 trucks per day and/or pollution with difficult sedimentation. A water clarifying plant is an investment but worth the money taking into account the advantages: A huge reduction in civil works costs, zero risk of sanding and blocking of nozzles, clean rinsing water, lower need of flocculent, little to no maintenance costs and automatic sludge discharge. A water clarifier is more costly than a series of scraper conveyors but only on short-term. Last but not least with clear water there is no chance of sandblasting trucks.

What are the advantages and disadvantages of a scraper conveyor?

For smaller work sites with low traffic a scraper conveyor is a cheap yet effective solution to lower maintenance on your wheel washer. With a scraper conveyor you do not need to manually empty the sludge in the washing water. In sandy conditions this works excellent as the sedimentation process goes quickly. When sedimentation is more difficult (for example with a clay pollution ) and traffic levels are high a scraper conveyor will be less advisory as only at nighttime the dirt will sink.

Why washing your wheels with a wheel washer?

When trucks coming from a worksite/quarry/landfill drive onto a public road, often their tires are contaminated. In order to prevent dirty and thus dangerous roads wheels need to be cleaned before entering the public road. A wheel washer is the quickest en simplest way to clean wheels.
