Qingdao Puhua Heavy Industry Machinery Co., Ltd., with over twenty years of experience in surface treatment equipment manufacturing, has developed a series of spray booth solutions that have been successfully applied in various fields such as automotive manufacturing, construction machinery, and rail transportation, providing customers with reliable professional support.
Spray booths achieve air purification through a three-stage filtration system: a pre-filter intercepts large particles, a medium-efficiency filter handles fine dust, and a high-efficiency filter ensures that the air delivered to the work area meets coating requirements. The temperature and humidity control system maintains the optimal temperature range of 18-28 degrees Celsius and humidity range of 45-65%, ensuring ideal curing conditions for all types of coatings.
Utilizing dry or wet paint mist treatment technologies, the system achieves a capture efficiency exceeding 98%. The dry system uses multi-layered filter materials to capture paint mist in stages, while the wet system uses a circulating water curtain for adsorption and filtration. Both systems reduce emission concentrations to below 15 milligrams per cubic meter, fully meeting national emission standards. An intelligent monitoring system displays emission data in real time and automatically generates environmental reports.
Multiple options are available to meet production needs: walk-in spray booths are suitable for assembly line operations, end-of-line designs facilitate the handling of large workpieces, and mobile structures adapt to flexible production requirements. Equipment widths from 3 meters to 8 meters can be customized as needed, and auxiliary devices such as electric doors and lifting platforms are provided to comprehensively enhance operational convenience.
Equipped with a complete safety system: explosion-proof electrical equipment, combustible gas detection alarms, and automatic fire extinguishing devices constitute three levels of protection. The lighting system uses explosion-proof LED lamps with an illuminance of over 500 lux, ensuring operators can clearly observe the coating effect. The system automatically activates an emergency mode when exhaust gas concentration exceeds the standard.
The equipment is equipped with a self-developed control system and a 10-inch touchscreen interface. The system can store over 100 process formulas. After the operator selects the workpiece type, the equipment automatically adjusts parameters such as airflow, temperature, and humidity. Remote monitoring allows real-time viewing of the equipment's operating status via computer and mobile phone.
The system adopts a variable frequency drive (VFD) ventilation system, automatically adjusting airflow according to actual needs, achieving energy savings of over 30% compared to fixed frequency systems. A heat recovery device recovers 60% of the heat from the exhaust air to heat the incoming air, significantly reducing energy consumption. The lighting system features zoned control and automatically shuts off when no one is operating.
We provide comprehensive services from planning to maintenance: initial assistance with site planning and process design; on-site guidance from professional engineers during installation; and post-delivery system operation training. Equipment files are established, and regular preventative maintenance is conducted to ensure long-term stable operation.
In multiple key projects, Qingdao Puhua Heavy Industry's paint booths have demonstrated superior performance:
After use by an engineering machinery company, the coating qualification rate increased from 92% to 98%.
Automotive parts manufacturers reported a three-level improvement in topcoat gloss consistency.
A rail transit equipment manufacturer confirmed that the equipment operated continuously for three years without major overhaul.
Qingdao Puhua Heavy Industry has established 16 service centers nationwide, equipped with a professional team of service engineers. Commonly used spare parts are stored in regional warehouses, and emergency requests are responded to within 24 hours. Quarterly equipment operation analysis reports are provided to customers, offering optimization suggestions. User training bases have been established, and regular operation and maintenance training courses are held.
With increasingly stringent environmental protection requirements and continuous upgrades in manufacturing processes, paint booth technology is developing towards greater intelligence and environmental friendliness. Qingdao Puhua Heavy Industry's R&D team is developing a new generation of intelligent paint booth systems, integrating IoT technology to achieve remote diagnostics and intelligent operation and maintenance. Simultaneously, equipment configuration schemes are being optimized for environmentally friendly materials such as water-based coatings and high-solids coatings.
Choosing professional spray booth equipment not only ensures coating quality and improves production efficiency, but is also a crucial guarantee for enterprises to achieve green production and fulfill their environmental responsibilities. Qingdao Puhua Heavy Industry will continue to dedicate itself to the innovation and improvement of spray booth technology, providing customers with better products and services, and jointly promoting technological progress in the industry.
