Karjoys presents the CE Approved Karjoys KJ-LS15 Ultra Automotive Spray Booth, a purpose-built solution designed for industrial-scale painting of large trucks, buses and other heavy vehicles. This diesel burner spray booth and electric LED spray booth hybrid integrates robust construction, advanced airflow engineering and customizable sizing to meet the demanding needs of high-throughput body shops and vehicle refinish centers. The Karjoys KJ-LS15 Ultra automotive spray booth delivers consistent finish quality, energy efficiency and safety compliance for professional operations

Product Overview and Key Features

The Karjoys KJ-LS15 Ultra automotive spray booth is engineered specifically for large truck spray booth applications. Its standard 15m length configuration accommodates the majority of full-size trucks and buses, while modular, customizable size options enable shops to scale the booth to fit extra-long vehicles or specialized equipment. Constructed with heavy-gauge steel panels and high-performance insulation, this automotive spray booth combines durability with thermal control to stabilize curing conditions and reduce ambient contamination

The booth is outfitted with a diesel burner spray booth heating system optimized for rapid temperature ramp-up and reliable operation in locations where gas may be impractical. For shops with electric infrastructure, the booth also supports electric heating and integrates high-efficiency LED spray booth lighting to enhance color accuracy and operator comfort. This combination of diesel burner spray booth capability and LED spray booth illumination makes the Karjoys KJ-LS15 Ultra versatile across climates and facility types

Applications and Use Cases

As a large truck spray booth, the Karjoys KJ-LS15 Ultra is ideal for fleet maintenance depots, municipal vehicle shops, bus body builders and commercial vehicle refinishers. Typical applications include full-body repainting, spot repair work, corrosion protection coating, and decorative graphics for buses and trailers. The booth’s generous interior volume and flexible size options accommodate double-shift operations and multi-stage painting processes, reducing bottlenecks in high-capacity facilities

For mobile service providers and remote refinish operations, the diesel burner spray booth configuration offers independence from extensive electric grids. The diesel burner spray booth option is well-suited to rural fleet services, construction company yards, and remote bus depots that require reliable heat for proper paint curing. Conversely, urban body shops can leverage the electric LED spray booth setup for cleaner energy profiles and simplified maintenance

Airflow, Filtration and Finish Quality

The Karjoys KJ-LS15 Ultra automotive spray booth incorporates an advanced downdraft airflow design to minimize overspray redistribution and particulate contamination. Air intake and exhaust are engineered for uniform airflow across the vehicle surface, ensuring even paint deposition and consistent film build. High-efficiency particulate filters and multi-stage filtration systems capture overspray prior to exhaust, protecting both the finish and the environment

By combining a downdraft architecture with precision filtration, the booth reduces rework and improves first-pass yield—critical metrics for any large truck spray booth operation. The controlled environment supports basecoat/clearcoat systems, single-stage coatings and high-solids formulations, allowing shops to run diverse paint products while maintaining predictable outcomes

Innovations and Technology Advantages

The Karjoys KJ-LS15 Ultra automotive spray booth differentiates itself through a series of targeted innovations. First, the customizable modular design allows operators to adapt booth length, width and door configurations without compromising airflow integrity—making it a practical large truck spray booth for varied fleet sizes. Second, the dual heating capability (diesel burner spray booth plus electric heating) affords maximum operational flexibility, enabling consistent curing across different installation contexts

Another innovation is the integrated LED spray booth lighting system. Unlike traditional fluorescent lighting, LED spray booth fixtures deliver high CRI illumination with low heat output and extended service life. This improves paint color matching, reduces maintenance downtime and cuts energy costs. Additionally, the electrical control panel includes programmable cure cycles that coordinate heat, airflow and LED intensity for reproducible paint cures—beneficial in multi-coat processes where timing and temperature are critical

Safety, Compliance and Energy Efficiency

Safety is paramount in any spray environment. The Karjoys KJ-LS15 Ultra is CE approved, reflecting compliance with relevant European safety and machine directives. The diesel burner spray booth heating system is engineered with fail-safes, flame supervision and automatic shutdown features to minimize risks associated with combustion-based heating. For electric LED spray booth configurations, redundant circuits and thermal monitoring ensure safe operation and quick fault detection

Energy efficiency is addressed through insulated panels, variable frequency drive (VFD) fans and LED lighting. The VFD-equipped ventilation system dynamically matches airflow to process stages—idle, spray, flash-off, and cure—reducing power consumption over continuous full-speed operation. The diesel burner spray booth mode is optimized for fuel-efficient combustion, while the electric LED spray booth mode leverages low-wattage fixtures to minimize electricity draw

Customization, Installation and Service

Karjoys supports tailored solutions for diverse facility layouts. The KJ-LS15 Ultra automotive spray booth can be ordered in standard or custom dimensions, with options for sectional expansion, additional inspection rooms, and integrated mixing rooms. Door types include high-speed sectional doors, sliding rails and insulated bi-fold variants to suit traffic patterns for large truck spray booth workflows. Optional features include remote monitoring, air quality sensors, and automated shutter systems

Installation is supported by Karjoys’ global service network, with step-by-step site assessment, foundation guidance and on-site commissioning. The modular design simplifies shipping and assembly, shortening the timeline from delivery to production. Comprehensive training and maintenance programs help operations optimize the diesel burner spray booth and LED spray booth systems, ensuring long-term reliability

Operational Benefits and ROI

Operators of the Karjoys KJ-LS15 Ultra automotive spray booth report improved throughput due to faster, uniform cure times and reduced rework. The ability to configure the booth as a diesel burner spray booth or electric LED spray booth reduces dependence on a single energy source and allows shops to adapt to fluctuating utility costs. High-quality finishes lower warranty claims and enhance fleet appearance—an important consideration for commercial operators and municipal fleets

The robust construction and low-maintenance LED lighting reduce lifecycle costs, while energy-saving controls and efficient heating provide meaningful operating expense savings. For large truck spray booth environments, these combined advantages translate to measurable improvements in output, quality and long-term return on investment

The CE Approved Karjoys KJ-LS15 Ultra automotive spray booth is a comprehensive solution for professional refinish operations focused on large trucks and buses. With modular sizing, dual heating options including diesel burner spray booth capability, and advanced LED spray booth lighting, the KJ-LS15 Ultra delivers consistent finish quality, operational flexibility and energy-efficient performance. Karjoys’ emphasis on safety, filtration and service support ensures the booth meets both production demands and regulatory requirements, making it an ideal choice for fleet depots, commercial body shops and large-scale refinish facilities
