Engineered to operate in high-temperature, highly demanding industrial processes with uncompromising quality and efficiency.
Shandong Zhangqiu Blower Co., Ltd. (formerly Shandong Zhangqiu Blower Works) has stood at the absolute forefront of China's air handling and thermal processing systems since 1957. By establishing two Sino-Japanese Joint-ventures and setting up a USA-based branch, we were the first enterprise in China's blower industry to execute overseas system deployment and local integration.
Following our successful listing on the Shenzhen Stock Exchange (Stock Code: 002598), our growth trajectory has integrated multi-disciplinary R&D across several manufacturing hubs, including Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang. Our core capability revolves around the holistic lifecycle design and engineering of high-efficiency Roots Blowers, Centrifugal Blowers, Heavy-Duty Fans, Industrial Slurry Pumps, MVR Evaporative Systems, and Pneumatic Conveying Infrastructure.
Technical whitepaper insights into modern thermal handling, mechanical stresses, and aerodynamics.
Operating temperatures exceeding 250°C demand critical separation of the mechanical drivetrain from the gas path. Modern high-temperature blower fans utilize specialized heat dissipation discs and heat-resistant barriers to shield internal bearings, extending oil life and preventing lubrication carbonization.
To reduce power consumption during variable thermal cycles, the integration of Permanent Magnet Synchronous Motors (PMSM) is becoming the standard. Direct drive PMSM eliminates belt transmission losses and allows step-less speed control based on real-time exhaust temp fluctuations, saving up to 30% in energy compared to traditional systems.
Handling hot, toxic, or moisture-laden vapors requires zero leakage. Advanced multi-stage carbon ring seals, labyrinth seals, and pressurized buffer gas systems isolate the process media. This technology is vital in hazardous applications like MVR (Mechanical Vapor Recompression) and high-temp flue gas desulfurization.
By centralizing manufacturing inside a state-of-the-art 430,000 m² industrial park, Zhanggu provides global procurement managers with unprecedented supply chain control, cost stability, and rapid lead times.
Analyzing thermal-aerodynamic system deployment across modern industries.
Moving toxic gases at elevated temperatures requires blowers with anti-corrosive treatments and explosion-proof configurations. Our C Series Cast Iron Multistage Centrifugal Blowers and Roots compressors are deployed to handle synthetic gases, vapor extraction, and catalytic cracking flue gas recirculation safely.
In mechanical vapor recompression plants, steam must be compressed to elevate its thermal capacity. The VR Series Steam Roots Compressor serves as a heavy-duty thermal booster, reducing factory energy demand by continuously recycling Latent Heat from industrial waste streams.
Transporting raw powders, fly ash, and granular slag in cement mills and coal-fired plants requires blowers that resist thermal fatigue and physical abrasive wear. The custom dual-stage tri-lobe roots blowers (e.g., ZG Series) offer stable pressure peaks and cooling jackets to sustain continuous pneumatic transport.
Zhanggu maintains state-of-the-art product lifecycle control through our integrated PLM system and Computer-Aided Manufacturing (CAM) technologies. Supported by computer-aided design (CAD) and process engineering platforms (CAPP), our design engineers can output 3D system drawings and layout validations within 24 hours of receiving customer specifications.
Our academic partnerships with leading institutions, including Tsinghua University, Xi'an Jiaotong University, and Shandong University, allow us to integrate advanced thermodynamics and flow dynamics simulations. This academic support keeps our blowers highly energy efficient and aerodynamically optimized.
