Heavy-Duty/Oversized Bus Maintenance, Spray Painting & Drying Systems

Spray Paint & Baking Booth Technical Specifications


I. Core Functions & Applications

1. Spray Painting Function

  • Provides an enclosed, dust-free environment to minimize particle contamination and ensure uniform coating.

  • Purifies air via multi-stage filtration (e.g., top/floor filter mats, activated carbon) to eliminate pollutants.

2. Baking/Drying Function

  • Rapid heating (50–80°C) accelerates paint curing, enhancing coating hardness and gloss.

  • Compatible with water-based paints, solvent-based paints, and powder coatings.


II. Structure & Components

1. Booth Structure

  • Materials: Galvanized steel or rock wool insulation panels (heat-resistant, anti-corrosion).

  • Dimensions: Customizable (e.g., length: 10–30 m, width: 4–8 m, height: 4–6 m).

2. Air Supply System

  • High-power centrifugal fan with optimized duct design for uniform airflow.

  • Top-mounted laminar airflow distribution system (perforated plates or Venturi structure).

3. Filtration System

  • Primary filtration: Captures coarse particles.

  • Intermediate filtration: Non-woven or fiberglass filter mats.

  • Advanced filtration: Activated carbon adsorbs VOCs and hazardous gases.

4. Heating System

  • Heat sources: Electric heating, natural gas, diesel, or infrared radiation.

  • Temperature control: PID intelligent control (±2°C accuracy).

5. Control System

  • PLC or touchscreen interface for programmable spray/bake cycles and temperature curves.

  • Safety alarms: Over-temperature, airflow failure, gas leakage.


III. Technical Features

1. High Efficiency & Energy Savings

  • Heat recovery systems (e.g., exhaust air recycling) reduce energy consumption.

  • Variable-frequency drive (VFD) fans adjust airflow to minimize power usage.

2. Smart Automation

  • Multi-stage temperature control profiles for diverse coating materials.

  • Remote monitoring and diagnostics (available in premium models).

3. Safety & Environmental Compliance

  • Explosion-proof design (for gas/diesel models) with flame detectors and automatic fire suppression.

  • Meets emission standards; optional RTO (Regenerative Thermal Oxidizer) for exhaust treatment.

4. Durability

  • Anti-corrosion coatings and high-temperature seals ensure a lifespan of 10+ years.


IV. Applications

  • Automotive: Full-body painting, truck/bus refinishing.

  • Industrial Machinery: Excavators, cranes, agricultural equipment.

  • Aerospace: Aircraft component coating.

  • Rail Transit: High-speed train/metro carriages.

  • Furniture Manufacturing: Large wood/metal furniture baking.


V. Selection Guidelines

  1. Workpiece Dimensions: Booth size should exceed maximum workpiece dimensions by ≥20%.

  2. Production Capacity: Prioritize models with rapid heating and recovery for continuous operation.

  3. Energy Source:

    • Electric: Ideal for eco-sensitive areas with stable power supply.

    • Gas/Diesel: Cost-effective for high-throughput facilities.


VI. Maintenance & Service

  1. Routine Cleaning:

    • Weekly filter cleaning; monthly duct inspections.

  2. Heating System Checks:

    • Quarterly inspection of burners or electric heating elements.

  3. Electrical Safety:

    • Annual calibration of temperature sensors and insulation integrity tests.

  4. Safety Valve Testing:

    • Regular pressure relief device checks for gas-powered systems.
