Automotive Industry: Process stability for maximum surface quality
In the automotive industry, controlled process air is a key factor for the quality of vehicle surfaces and the efficiency of engine manufacturing. The fields of application range from painting lines and cooling in mechanical processing to wind tunnel test benches. Quality Made in Germany guarantees the extreme smooth running and reliability that are absolutely essential in just-in-time production.
Challenges and risks in ramp-up production
The biggest challenge in the automotive industry is avoiding contamination in the paint booths and ensuring the absolute reliability of the systems. Even the smallest vibrations or particles in the air supply lead to paint defects that require expensive rework. Since the painting line is often the bottleneck of production, a failure of the ventilation technology leads to an immediate standstill of the entire plant. This not only causes enormous costs due to production downtime but also endangers the entire supply chain and compliance with strict delivery deadlines for end customers.
Solutions and retrofit expertise: Precision in every cycle time
Siempelkamp Industrial Fans supports automotive manufacturers with high-precision centrifugal fans characterized by extremely low vibration and exact controllability. Highly efficient inlet vane controls are used for the efficient regulation of supply air volumes. Our tailor-made acoustic enclosures and silencers ensure the necessary quietness in production, while specialized filter units guarantee the purity of the process air.
In the field of retrofitting, we offer the energy-efficient refurbishment of outdated painting plants – independent of the original manufacturer, including fans from competitors. By using flow-optimized impellers and modern drive concepts, we drastically reduce the energy costs of the painting and drying systems. Our full service – from vibration measurement to preventive maintenance – ensures maximum availability worldwide and helps to achieve the CO2 targets of automotive production through efficient air technology.
