    Industrial spray booths for large vehicle finishing

    When working on special-purpose vehicles, construction machinery or firefighting units, the coating process needs to match the size and shape of these vehicles. These vehicles are often very tall, very long or shaped in a non-standard way, so the airflow, heating and access points need to be set up to match their size. Open spraying areas and regular automotive booths usually don’t have enough height, booth length or airflow strength to deal with this type of work. Large spray booths designed for buses and trucks offer the space and control needed for these projects. Their extended booth length, reinforced airflow and higher heating capacity support consistent coating on long or uneven surfaces. Full-size doors and side access points also make it easier to reach different parts of the vehicle during both manufacturing and repair work. With the right heat distribution, the curing stage becomes more stable, which helps the coating last longer on vehicles that work outdoors or under heavy use.

    Optional Configurations
    Structure
    Split Booth

    Split Booth

    The spray booth can be configured with a dividing door system, allowing the interior to be separated into two sections.
    Depending on the project layout, you can choose between a folding door or an electric roller door for this split configuration.

    Outdoor Booth

    Outdoor Booth

    When indoor space is limited, an outdoor spray booth becomes a practical solution.
    An exterior protective structure can be added around the spray booth to shield it from rain, wind, and other harsh weather conditions, ensuring stable performance throughout the year.

    Auxiliary Equipment
    3-Axis Movement Platform

    3-Axis Movement Platform

    The 3-axis movement platform provides easier and safer access to higher areas inside large spray booths, especially when working with buses, trucks or oversized components. Its three-direction movement system gives operators stable and efficient reach at elevated positions.

    Heat Recuperator

    Heat Recuperator

    The heat recuperator allows the system to reuse part of the hot air that would normally be exhausted. This recirculation helps reduce energy consumption during operation, providing a more efficient heating process inside the spray booth.

    Bus and truck paint booths can be equipped with gas, diesel or electric heating, either as a single option or as a mixed setup. For example, a typical configuration may use a 232 kW stainless-steel heat exchanger together with a Riello RG5S diesel burner rated at 260,000 kcal/h. The heating capacity is enough for curing buses and trucks, incluso when the surfaces are large or the coating layer is thicker.

    These booths follow EN779 filtration standards and can use filters such as G3 and F5. They can also be fitted with activated-carbon adsorption and RCO (regenerative catalytic oxidation) systems, giving VOC removal rates above 90%. For safety, the design includes explosion-proof components, gas detectors and a linked CO₂ fire-suppression system. All these features help the booth meet environmental requirements and maintain safe operation throughout the process.

    The booth uses an automatic temperature control system with an accuracy of about ±2°C. Maintaining a steady temperature is important as it allows the coating cure evenly, so the paint adheres better and dries smoothly, without any noticeable issues. When the heat fluctuates too much, large panels can develop cracks or uneven areas, so this level of control plays an important role in maintaining a smooth and consistent finish on buses and trucks.
