Spray Paint Room 7000×5100×3300mm PLC System

Optimized Structural Design for Safety and Durability

The Spray paint room features an external dimension of 7000 × 5100 × 3300mm and an internal working space of 6900 × 3900 × 2650mm, providing sufficient room for vehicle refinishing and medium-to-large component coating.

Structural highlights include:

• 50mm flame-retardant EPS insulation wall panels with 0.42mm color steel plates

• 0.8mm galvanized bent iron ceiling structure

• Three sheet metal doors (3000 × 2600mm)

• Dedicated safety operation door (750 × 1900mm)

• Pressure relief device and bottom drainage system

This configuration ensures high fire resistance, thermal insulation performance, and structural rigidity. The flush-fit construction and reinforced panels support long-term industrial operation under high temperature and airflow conditions.

Electric Heating System for Stable Temperature Control

Temperature control is critical in any Spray paint room to guarantee consistent curing and coating adhesion.

This system is equipped with:

• 10 sets of double-door electric heating systems

• 380V, 50Hz industrial voltage

• PLC frequency conversion control

The electric heating configuration allows uniform temperature rise and stable curing performance. Compared to traditional fuel-based systems, electric heating provides:

• Cleaner operation

• More precise temperature adjustment

• Reduced emissions

For automotive body shops and industrial coating facilities, stable heat distribution minimizes paint defects such as orange peel, blistering, or uneven gloss.

Advanced Ventilation and Airflow Management

Airflow stability directly impacts overspray control and finish quality.

The Spray paint room adopts a top-down air supply and lower-chamber exhaust system, which creates balanced vertical airflow across the workspace.

Key ventilation components:

• 2 × 4kW centrifugal fans

• 1 × 7.5kW exhaust fan

• 4 rectangular air ducts

• 90° and 45° elbow connectors

This configuration ensures consistent air circulation and efficient paint mist extraction. Overspray is directed downward and discharged through the lower chamber, improving operator safety and maintaining clean airflow paths.

Such airflow design is widely recognized in professional refinishing environments as a best practice for achieving uniform coating thickness.

Multi-Stage Filtration for Environmental Compliance

Environmental standards require efficient removal of particulate matter and VOCs in industrial Spray paint rooms.

This system integrates a multi-stage filtration structure:

• EU5 top purification layer

• F9 grade inlet filter cotton

• Bottom multi-layer fiberglass cotton

• Activated carbon cotton for paint mist and VOC filtration

This layered filtration approach ensures:

• Effective capture of fine paint particles

• Reduced emission of harmful gases

• Cleaner working conditions

For industrial coating plants and engineering contractors managing environmental systems, this level of filtration supports compliance with modern environmental requirements.

High-Efficiency LED Lighting Layout

Lighting quality directly affects visual inspection and finishing accuracy.

This Spray paint room includes:

• 8 sets of 4 × 18W LED ceiling lamps

• Installed at 45° angle for shadow-free illumination

• 10 additional side-mounted integrated LED fixtures

• Painted light box shells for enhanced reflectivity

The angled lighting layout minimizes blind spots and ensures accurate color matching during painting operations. This is especially critical in automotive refinishing and high-end furniture finishing.

Intelligent PLC Control System

The integrated PLC frequency conversion control system enables precise adjustment of:

• Airflow speed

• Heating intensity

• Operational modes

Benefits include:

• Energy-efficient operation

• Stable performance under varying load conditions

• Simplified operator interface

For large-scale workshops and OEM coating lines, automated control enhances process repeatability and reduces manual intervention.
