Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) represents over a half-century of continuous evolution, engineering precision, and market leadership in industrial blower and compressor technologies. Founded with a vision to deliver unmatched mechanical efficiency, ZCBC has emerged as the executive director unit of the China General Machinery Industry Association and the vice president unit of the Association's fan branch.
On July 7, 2011, ZCBC achieved a historic milestone by listing on the Shenzhen Stock Exchange (Stock Code: 002598), positioning itself as a highly transparent, financially robust, and growth-oriented enterprise. In 2020, our parent company recorded an impressive operating income of 1.5 billion yuan with a net profit of 150 million yuan, spanning 20 holding companies and managing four strategically positioned manufacturing bases in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu).
With R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi, ZCBC fuses multi-disciplinary expertise to push boundaries in aerodynamics, mechanical engineering, and smart controls, realizing an integrated service network covering design, manufacturing, sales, and aftermarket operation & maintenance (O&M).
Our overall development strategy—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—is powered by our singular working concept: "Do the best." This principle drives our multi-faceted portfolio, including:
At the center of sustainable chemical processing and zero liquid discharge (ZLD) systems lies Mechanical Vapor Recompression (MVR). The Centrifugal Steam Compressor is the technological heart of this loop, responsible for compressing secondary steam generated by the evaporator. This process elevates the vapor's pressure, temperature, and enthalpy, directing it back to the heating chamber as a clean, highly efficient heating source. The result is a dramatic reduction in external boiler steam demand, cutting energy consumption by up to 90% compared to traditional multi-effect evaporation.
Our centrifugal steam compressors are built around advanced aerodynamic design principles, ensuring optimized polytropic and isentropic efficiency under variable load profiles. Utilizing high-strength Duplex Stainless Steel (2205/2507) or Titanium Alloy impellers, our systems withstand the harsh corrosive environment of high-temperature vapor compression.
The impeller is designed using 3D viscous CFD fluid simulation software, optimizing the blade profile to reduce separation losses and suppress localized turbulence. This design delivers stable flow rates and prevents surging, extending the operating range of the compressor across diverse process envelopes.
In 2005, ZCBC transitioned to a newly built, high-standard modern industrial park spanning an expansive 430,000 m². Equipped with advanced office buildings, state-of-the-art testing centers, and automated manufacturing lines, this facility provides the robust physical infrastructure required to support large-scale, high-precision international projects.
We believe that structural integrity and aerodynamic efficiency begin with world-class design tools. ZCBC leverages an advanced Product Lifecycle Management (PLM) system integrated with Computer-Aided Manufacturing (CAM), Computer-Aided Process Design (CAPP), and Computer-Aided Testing (CAT) systems. This digital thread ensures that every component is tracked from raw material analysis to final runtime diagnostics.
Our machining workshop hosts nearly 100 sets of advanced processing equipment, including five-axis machining centers imported from Japan and Germany, high-precision CNC boring machines, and heavy-duty coordinate measuring instruments (CMM) for micrometer-level quality assurance.
Centrifugal steam compressors are critical for driving operational efficiency and reducing carbon footprint across multiple heavy industries. ZCBC develops customized system configurations adapted to specific process dynamics:
MVR evaporators extract pure water from chemical, coal, and power plant wastewater, generating clean distillate for process reuse and achieving zero liquid discharge. The compressor manages highly variable steam properties while resisting acidic gas corrosion.
In vacuum salt production, potash concentration, and organic synthesis crystallization, ZCBC centrifugal steam compressors handle continuous duty cycles, ensuring uninterrupted operation with high thermal recovery rates.
Our MVR crystallization systems are critical in refining lithium carbonate, cobalt sulfate, and nickel sulfate. Precise thermal profiling enables the synthesis of battery-grade precursors while lowering electricity consumption.
As the industry transitions to intelligent manufacturing, ZCBC's technology roadmap incorporates key performance innovations:
By suspending the shaft using controlled electromagnetic forces, AMBs eliminate friction, mechanical wear, and the risk of oil contamination in the process steam, allowing for higher rotational speeds and longer system lifetimes.
Eliminating conventional gearboxes minimizes transmission losses, reduces footprint, and offers variable speed adjustments for optimized aerodynamic performance across fluctuating process flows.
Using vibration sensors, temperature probes, and dynamic pressure transducers, our integrated software monitors real-time surge margins, predicting maintenance intervals before mechanical failures occur.
To serve the complex international market, ZCBC has built robust global networks, establishing two Sino-Japanese joint ventures and a dedicated branch in the USA. This localized presence ensures direct communication, fast technical support, and seamless integration with Western engineering standards.
Our commitment to quality is backed by comprehensive certifications and a strong portfolio of proprietary technologies. ZCBC holds 69 patents (including 5 major invention patents) and 2 software copyrights. Our production lines conform to global management benchmarks, including:
Corporate culture is the soul of our development. With the strategic policy of "Do the best," ZCBC values individual contributions and fosters a high-performance environment. Our R&D team features leading senior engineers, domestic and foreign turbomachinery experts, and academic leaders. Supported by postgraduate workstations and academic partnerships with Tsinghua University and Xi'an Jiaotong University, ZCBC maintains a pipeline of technical expertise in industrial aerodynamics.
Understanding regional compliance challenges is key for global project delivery. ZCBC offers 3D CAD design submittals within 24 hours, assisting system integrators in mapping physical piping interfaces and calculating seismic loading. We guide projects through design, manufacturing, inspection, and commissioning, ensuring reliable operation in over 70 countries.
