Vehicle Undercarriage & Chassis Wash Systems

Powerful Chassis Wash Solutions for Heavy-Duty Vehicles, Trucks, & Buses

Designed for buses, trucks, heavy-duty fleets, military vehicles, and mining operations, InterClean’s chassis wash systems deliver efficient and powerful underbody cleaning. Our wash systems remove road salt, dirt, and corrosive buildup to reduce maintenance costs, safeguard critical components, and extend vehicle life.

We offer several chassis wash system options, including spray bars, spinners, FST, and CTW configurations. Whether you need an undercarriage wash system installed for transit vehicles, a fleet of trucks, mining equipment, or military vehicles, we have you covered. 

With our expertise, you’ll experience fast installation times and minimal disruption to your wash bay. Our systems can function as stand-alone units, integrate into a new InterClean wash setup, or enhance an existing wash bay, helping you keep vehicles clean and protected from corrosion, dirt, and grime.

Spinner Chassis Wash

A wash system that uses rotating nozzles to strip caked mud and grime from the undercarriage in a single pass.

  • Deep Cleaning Power – Centri®Spinner nozzles remove grime, dirt, and corrosive materials with high-volume, high-pressure rotating sprays.
  • Superior Coverage – Rotating nozzles deliver twice the wash coverage of standard sprays, maximizing cleaning performance in every pass.
  • Reliable Performance – Each new Centri®Spinner operates at 15-25 GPM with pressures up to 300 PSI and includes a three-year factory warranty.
  • Customizable for Heavy-Duty Use – Integrate multiple Centri®Spinners into your wash system to customize undercarriage cleaning, even for demanding jobs such as heavy mud removal.

Spray Bar Chassis Wash

Reliable chassis wash systems built for thorough undercarriage cleaning in fleet operations that demand frequent washing.

Standard Spray Bar Chassis Wash

Clears road salt and grime from trucks or buses on every regular wash cycle.

  • Flexible Installation & Water Use – Can be installed as an under-ramp or in-ground system, using fresh or reclaimed water at adjustable flow rates and pressure.
  • Optimized Cleaning Performance – Adjustable stainless steel fan spray nozzles, arranged in a staggered pattern, provide complete wash coverage

Oscillating Centri®Spinner Spray Bar

Our chassis wash system delivers powerful cleaning for stationary vehicles and is built to handle heavy-duty industrial and commercial undercarriage applications.

  • Scalable for Large Fleets – Multiple modules can be combined to extend undercarriage wash coverage for semi-trucks, making it an ideal wash system for high-volume fleet operations.
  • Comprehensive & High-Pressure Cleaning – The oscillating spray bar, featuring 10 Centri®Spinner nozzles per module, delivers 15 GPM at 300 PSI per nozzle, resulting in a total of 150 GPM per module.

Why Use Our Chassis Wash Systems

Cleaning the underbody of your vehicles is essential for preventing corrosion and rust caused by work-site conditions, winter chemicals, and road debris. Our high-performance chassis wash strips away the grime, mud, contaminants, grease, chemicals, and other buildup that can contribute to costly repairs.

Reduce Maintenance Prep Time

Have your vehicles cleaned and ready for inspection or repair faster. Our chassis wash systems quickly remove built-up grime, debris, and salt from the undercarriage, allowing your maintenance crews to access critical components without spending time manually cleaning the vehicle. By reducing time spent on cleaning, technicians can begin inspections, diagnostics, and repairs much sooner.

Increase Sustainability

Equip your wash system with the optional EQ100 high-pressure, anti-turbulent water-recycling module, designed to reclaim up to 90% of wash water without chemical additives. This feature reduces your reliance on high volumes of fresh water for every wash. The EQ100 module can produce up to 300 GPM of recycled, clean, and optically clear water without compromising wash quality or performance.

Prolong Vehicle Lifespan

Heavy machinery and vehicles returning from tough days at construction sites or industrial sites often have their chassis and tire treads coated in debris, mud, and harmful contaminants. If left uncleaned, this buildup can add weight and accelerate wear on the braking and driveline systems. InterClean’s chassis wash systems effectively remove dirt, grime, and corrosive materials from the undercarriage, helping extend vehicle lifespan while reducing maintenance costs across your fleet.

Enhance Safety

InterClean’s automated chassis wash systems provide a fast, reliable solution for cleaning vehicle underbodies. Vehicles are cleaned automatically, whether driving through or held stationary, with no manual scrubbing required, reducing exposure to safety hazards and limiting the risk of contaminants entering your facility. A cleaner undercarriage also makes it easier to inspect and maintain vehicles, supporting safer operations.

Regardless of the type of equipment in your fleet, InterClean offers chassis wash systems tailored to your needs, so that vehicles maintain peak performance.
