High-Performance Professional Automotive Full Downdraft Spray & Bake Booth Refinishing Enclosure for 4S Centers & OEM Applications

Technical Overview: The CT-800 is engineered to provide a Class A refinishing environment by utilizing a true Full Downdraft airflow principle. Unlike semi-down or cross-draft systems, the CT-800 pressurizes the entire ceiling plenum, forcing HEPA-filtered air vertically over the vehicle at a constant velocity (0.25 – 0.35 m/s). This laminar airflow instantly suppresses overspray and airborne particulates into the floor filtration system, ensuring a contamination-free finish essential for waterborne and high-solid clearcoats.

Key Engineering Features:

1. Airflow Management System:

   • Intake: 2x 4KW Turbo Centrifugal fans (total 24,000 m³/h) with pre-filtration.

   • Ceiling Plenum: Equipped with EU5 fine diffusion filters (600G standard) to ensure equal air distribution and capture particles down to 5 microns.

   • Floor Extraction: Full basement metal base with generous airflow grating and fiberglass paint-stop filters to capture heavy overspray.

2. High-Efficiency Thermal Cycle:

   • Heating Unit: Utilizes a genuine Italian Riello G20 Diesel Burner (or optional direct-fired natural gas burner) paired with a high-grade stainless steel (SUS304) heat exchanger.

   • Performance: Achieves a ΔT of 60°C (e.g., 20°C to 80°C baking temp) in approximately 6–8 minutes with >90% thermal efficiency.

3. Structural Insulation:

   • Wall Panels: 75mm thick tongue-and-groove interlocking panels. Available in EPS (Polystyrene) for standard insulation or Rock Wool (Mineral Wool) for superior fire resistance and thermal retention.

   • Steel Skin: 0.476mm pre-painted galvanized steel sheeting.

4. Shadow-Free Illumination:

   • Ceiling: 32x 24W LED tubes mounted at a 45° angle.

   • Walls: 16x 24W LED tubes mounted horizontally at waist height.

   • Output: Guaranteed illumination of ≥1000 Lux with high Color Rendering Index (CRI) for accurate color matching.

Product Overview Designed for modern body shops requiring compliance with environmental regulations, our Electric Heating Paint Booth offers a clean, efficient, and safe alternative to traditional diesel burners. This booth is engineered for high-quality surface refinishing, suitable for sedans, SUVs, and small vans.

Why Choose Electric Heating?

1. Uniform Temperature: The electric heating exchangers provide a stable curing curve, essential for preventing paint defects like "orange peel" or solvent pop.

2. Low Maintenance: No burner nozzles to clean, no diesel filters to change.

3. Cost-Effective: With the rising cost of fossil fuels, electric heating (especially when paired with targeted usage) offers a predictable operational cost.

Construction Quality

• Wallboard: We use high-density EPS foam (14kg/m³) for excellent thermal insulation.

• Plenum: The upper static pressure chamber is galvanized steel, designed to equalize air pressure across the ceiling filters for perfectly vertical airflow (Down-draft).

Application Ideal for 4S service centers, high-end car repair shops, and custom body modification studios. Can be integrated into a larger Paint Line workflow for continuous production
