Truck wheel wash system

Service in detail

Truck wheel wash system

A truck wheel wash system is far more than just a cleaning unit – it serves as a vital interface between your site and the public infrastructure. It ensures that mud, clay, and dirt are removed right at the source, thereby maintaining traffic safety and making it easy to comply with legal requirements regarding road cleanliness.

Truck wheel wash system for heavy-duty vehicles with mobile kit

Our truck wheel wash systems feature a modular design and are available in various lengths and performance capacities. With a standard axle load capacity of 15 tonnes and a clear width of 3 metres, they are engineered to accommodate all types of heavy-duty vehicles, ranging from trucks to tractors with trailers.

Depending on your requirements, the systems can be installed permanently or set up flexibly above ground using a mobile kit, an ideal solution for changing locations and temporary construction sites. Pictured here is a 4 metre long system, equipped with a mobile kit and a generator, at a construction site in Kaub am Rhein.

A Truck wheel wash system is a specialized cleaning installation positioned at the exits of industrial or construction sites. Its primary purpose is to remove dirt from the tires, rims, and undercarriages of commercial vehicles as they pass through. This prevents mud and stones from being carried onto public roads.

The principle behind our Sunny-Wash DownPour series is based on a highly efficient low-pressure, high-volume process:

  • The cleaning process: The truck drives through the system at a walking pace.
  • High water volume instead of high pressure: Rather than using high-pressure jets, our systems flush away dirt using an enormous volume of water. Depending on the model, the water flow rate ranges from 1,700 l/min for the smallest model (2m EASY-wash) up to 24,000 l/min for the 12m ULTRA-wash.
  • Targeted spray force: Water is discharged through a large number of specialized nozzles (ranging from 80 to 1,368 units) at a pressure of approximately 1.4 to 2.0 bar. This is gentle on the vehicle’s mechanical components while still effectively removing deeply embedded dirt from profiles and crevices.
  • Closed-loop system: The wash water is collected in large basins (up to 350 m³ for the ULTRA-wash model), cleaned via sedimentation, and recirculated back into the system.

A wheel wash system is essential for any operator using heavy vehicles on unpaved ground who must also comply with legal requirements regarding road cleanliness:

  • Gravel pits and quarries: To manage high volumes of truck traffic.
  • Construction sites and earthworks: Particularly where the soil consists of clay or loam, which—without professional cleaning—would dangerously contaminate public roads.
  • Landfills and recycling centers: To prevent the spread of contamination and the tracking of mud off-site.

Our systems can be found wherever heavy equipment and high operational tempo define the daily workflow:

  • Gravel and sand pits: Rapid cleaning with high throughput.
  • Construction sites & earthworks: Reliable protection against the fouling of public roads.
  • Landfills & recycling centers: Effective management of heavy soiling, such as silt or clay.
  • Equipment rental fleets: Fast turnaround times to prepare machinery for its next deployment.

Why Sunny-Wash is the best choice for your business

Sunny-Wash systems are designed for demanding applications on construction sites and in industrial settings. Each unit combines well-conceived engineering, high-quality components, and ease of operation to ensure reliable performance under real-world conditions.

Robust steel structural framework & extreme durability

Our systems are designed for maximum loads. With a design for Standard Axle loads from 15,000 kg to 30,000 kg, the steel structure offers the necessary stability.Higher axle loads for wheel loaders or large dumpers are also possible.

Plug & Play Installation

Time is in short supply on construction sites. DownPour series (SW-DP) are designed for rapid commissioning. Installation follows the plug-and-play principle: deliver, set up, connect, fill with water – and it is ready for immediate use.

Modular design instead of rigid welded construction

The decisive advantage: our systems are not unwieldy, fully welded monoblocks. Instead, they consist of precisely manufactured individual components.

Scalable performance for every need

EASY-washFrom a model with 80 nozzles to the high-performance ULTRA-wash With up to 1,368 nozzles and a water flow rate of 24,000 l/min, we offer the right technical solution for any volume of truck traffic.

Easy to repair

In the event of damage, there is no need to replace the entire system or carry out complex welding work on-site. Individual components can be replaced in a targeted and cost-efficient manner.

Ease of maintenance

The modular design allows for easy access to all relevant areas, which significantly simplifies regular maintenance.

PERFORMANCE LEVELS

Sunny-Wash truck wheel wash systems are available in several configurations and can be precisely adapted to varying degrees of soiling and operational conditions. Each level offers a tailored washing action—ideal for everything from construction sites with light soil contamination to areas characterized by heavy mud and cohesive soils, such as loam or clay.

The Right Choice: Performance Classes & Pool Sizing

A tire-washing system is only as efficient as its water management. Depending on the degree of soiling and the frequency of truck traffic, the requirements for the minimum water storage volume vary significantly.

1. Entry-level solutions for light soiling

Ideal for sand, gravel or light mud deposits.EASY-wash (SW-DPe):  The compact solution for up to 25 trucks per day. Requires a minimum water supply of 12 m³.REGULAR-wash (SW-DPr): The standard for medium frequencies (up to 100 trucks/day). Depending on the version (4m to 12m), a storage capacity of 17 m³ to 110 m³ should be factored in. Wheel wash system EASY-wash on a construction site

2. Power solutions for moderate to heavy soiling

When soil, silt, or stiff clay are involved, the requirements for water throughput and basin volume increase.POWER-wash (SW-DPp): This system can handle up to 150 trucks per day, assuming a medium level of soiling. For this, we recommend a basin volume of  30 m³ till 140 m³.MEGA-wash (SW-DPM): Our powerhouse for large construction sites with around 200 trucks per day. Due to the massive water flow of up to 15,600 l/min, a corresponding reservoir of 40 m³ to 250 m³ is necessary to effectively ensure sedimentation.

3. High-end solution for extreme conditions

  • ULTRA-wash (SW-DPu): Designed for over er 300 Trucks per day and the toughest conditions such as clay or heavy loam. To achieve the gigantic pumping capacity of 24.000 l/min To keep them stable, pelvic sizes of 120 m³ bis 350 m³ necessary.

The heart of our systems: Tsurumi submersible pumps

Tsurumi submersible motor pumps as part of the truck wheel wash system

The efficiency of a tire washing system depends entirely on the quality of its pump technology. That’s why we focus on Sunny–Wash consistently focused on high-performance pumps of the brand Tsurumi. These pumps are known worldwide for their unsurpassed robustness and durability under extreme conditions.

Why we chose Tsurumi  decided  haben

Thanks to patented oil-lifter technology, Tsurumi pumps are extremely resistant to overheating, even if the water level in the basin drops significantly.<span class="EOP SCXW244542037 BCX0" data-ccp-props=""134233117":true,"134233118":true,"201341983":0,"335559740":240"> 

The pumps are specifically designed for water containing sand and sludge.By using highly wear-resistant materials, they easily withstand the abrasive forces present in recycled water.
