Project Implementation and Operating Results
Recently, a high-end polyarylether engineering plastics production project with a total investment of CNY 685,000,000 by a certain new materials company was successfully launched and put into production, marking a new addition to domestic high-performance specialty materials capacity. BOSAN, as the core air supply system partner, customized an integrated solution combining a 220 kW water-cooled, two-stage variable-speed screw air compressor and a dedicated nitrogen generator for the project, using robust equipment capabilities to safeguard the entire production process of high-end new materials, setting a new benchmark for industry air supply support.
01. Compressed Air for High-end Material Production
Polyarylether engineering plastics (such as PEEK) are known as the "gold of plastics". With their excellent properties of high temperature resistance, high strength, and corrosion resistance, they are widely used in high-end fields such as aerospace, new energy vehicles, and medical implants. The production process is extremely demanding. The core production stages require extremely high standards for the cleanliness, stability, and continuity of compressed air and high-purity nitrogen — the quality of the gas source directly determines the product purity, performance stability, and production yield. Even trace impurities or pressure fluctuations can lead to batch product rejection, making it a key bottleneck in the mass production of high-end new materials.
02. A Customized BOSAN System
To meet the project's high-precision and high-load production requirements, the company went through multiple rounds of technical comparisons and on-site inspections, and ultimately chose BOSAN, introducing a professional complete industrial gas source system solution.
Two-stage compression and permanent-magnet variable-speed control for efficient, stable operation
Equipped with advanced two-stage compression and permanent-magnet variable-speed technology, it uses over 30% less energy than traditional models, and can automatically adjust the speed according to compressed-air demand, reducing no-load loss under partial load. The screw air end paired with precision rotor profiles operates stably with low loss, and the life of core components exceeds 40,000 hours.
Water cooling supports continuous high-load operation
The water-cooled design matches heat-exchange capacity to cooling-water temperature, quality and flow. It supports continuous, high-load operation 24 hours a day, seven days a week, helping prevent high temperatures from reducing energy efficiency or causing equipment failures and interrupting the compressed-air supply.
Clean compressed-air supply matched to process standards
The entire system is equipped with a dedicated nitrogen generation unit, capable of producing clean compressed air and high-purity nitrogen. The oil content in the compressed air is ≤ 0.01 ppm, and the nitrogen purity meets the stringent requirements for the production of polyarylether materials, reducing impurity contamination and fully ensuring stable product performance and batch consistency.
Integrated intelligent management and control, reducing costs, increasing efficiency, and facilitating operations and maintenance
The integrated control system monitors key parameters, including pressure, temperature and energy consumption, in real time. Automatic fault warnings and remote operation and maintenance simplify workflows and reduce labour costs, helping companies manage their compressed-air supply intelligently.
03. Supporting Industrial Upgrading through Advanced Manufacturing
The successful commissioning of this project is another important benchmark case for BOSAN in deepening its presence in the high-end new materials field, fully validating BOSAN's technical strength and delivery capability in customized process-gas supply systems with high cleanliness and stability. As a leading domestic brand of high-end industrial gas source equipment, BOSAN has always focused on high-end manufacturing sectors such as aerospace, nuclear power, new energy, and semiconductors. Relying on extensive technical expertise and high-quality complete equipment and customized system solutions, it breaks the monopoly of foreign brands, promotes quality improvement and efficiency enhancement in the new materials industry, and empowers the high-quality development of domestic high-end manufacturing!
