Explore our high-performance product range engineered to integrate seamlessly into MVR systems, chemical processing, and municipal wastewater applications.
Founded with a legacy that spans over 50 years in professional blower design, manufacturing, and flow dynamics, Shandong Zhangqiu Blower Co., Ltd. (ZCBC) has transitioned from a domestic industry leader to a global pioneer in Mechanical Vapor Recompression (MVR) technologies. Formerly known as Shandong Zhangqiu Blower Works, we have engineered systems that form the backbone of modern evaporative and crystallization processes across 70+ countries.
Our strategic expansion includes setting up two Sino-Japanese Joint-ventures and a dedicated branch in the United States, positioning us as the first company in China's blower industry to establish an overseas network. By anchoring our design logic in thermodynamic efficiency, ZCBC continues to deliver state-of-the-art vapor compressors, heavy-duty industrial pumps, pneumatic conveying setups, and turnkey wastewater crystallization projects that minimize industrial carbon footprints.
Our core operating philosophy is simple: "Do the best". This guiding light drives our multi-disciplinary engineering teams to optimize mechanical efficiency, extend runtime cycles, and reduce total cost of ownership (TCO) for global process industries.
Decarbonization, Zero Liquid Discharge (ZLD), and the rise of thermodynamic closed-loop cycles.
Traditional multi-effect evaporators consume large volumes of fresh steam and dump thermal energy through cooling towers. Modern industrial trends emphasize recycling latent heat. By utilizing a Zhangqiu Vapor Compressor, the low-pressure waste steam from the evaporator is mechanically compressed, raising its pressure and saturation temperature, allowing it to act as the heating source for the same evaporator. This reduces electricity and thermal energy overheads by up to 60-90% compared to traditional configurations.
Strict environmental regulations across North America, Europe, and the APAC region require chemical, pharmaceutical, and mining facilities to implement zero liquid discharge water treatment systems. MVR crystallization systems driven by our highly custom Roots and centrifugal vapor compressors isolate salts and minerals from wastewater, ensuring water recycling rates above 98% and compliance with global water quality standards.
MVR systems operate under severe corrosive and abrasive environments due to highly concentrated brines and acids. Modern procurement demands heavy-duty metallurgy. Zhangqiu Blower meets this challenge by using high-grade materials such as Duplex Stainless Steel (2205/2507), Titanium Grade 2, and Hastelloy for compressor impellers, casings, and internal seals to prevent premature corrosion cracking and fatigue.
In 2005, ZCBC relocated to a state-of-the-art industrial park covering 430,000 m², designed to foster deep research, manufacture high-precision components, and accommodate joint-venture collaborations. This facility enabled ZCBC to achieve listing status on the Shenzhen Stock Exchange on July 7, 2011, establishing a key milestone in our commercial expansion.
By 2020, our parent group reached an operating income of 1.5 billion yuan with a profit of 150 million yuan, highlighting our financial stability and scalability. Today, ZCBC coordinates across 20 holding companies, operating four major production centers in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, along with dedicated technology R&D facilities in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Our engineering ecosystem links directly with esteemed academic institutions, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University, integrating academic innovations into commercial-grade vapor compressor systems.
How our custom engineering solves complex process problems for chemical, pharmaceutical, and water treatment projects.
With the surge in EV battery production, processing lithium and cobalt raw materials requires stable crystallization. Our custom centrifugal MVR vapor compressors maintain high pressure ratios and precise vapor temperatures to produce high-purity lithium carbonate and lithium hydroxide, keeping downtime to a absolute minimum.
Industrial wastewater from chemical refineries contains high percentages of NaCl and Na2SO4. Our anti-sticky and wear-resistant coating technologies prevent salt scaling inside the compressor chamber, guaranteeing continuously high thermal performance and lower cleaning cycles.
Concentrating pharmaceutical solutions requires precise low-temperature boiling conditions to avoid destroying organic active ingredients. ZCBC vacuum pumps combined with Roots vapor compressors provide reliable vacuum ranges and low boiling points for gentle thermal evaporation.
To assure accuracy, durability, and thermodynamic stability, Shandong Zhangqiu Blower Co., Ltd. implements full lifecycle digital integration. Our engineering team utilizes global-standard Product Lifecycle Management (PLM) systems, Computer-Aided Process Design (CAPP), Computer-Aided Manufacturing (CAM), and Computer-Aided Testing (CAT). This ensures that every rotor balance profile, impeller tolerance, and structural calculation meets optimal efficiency ratings before entering physical production.
We boast nearly 100 sets of imported high-precision machines, including 5-axis CNC machining centers, Japanese and German high-accuracy coordinate measuring instruments, and ultrasonic non-destructive flaw detectors. These tools enable us to manufacture impellers with complicated twisted profiles, achieving maximum hydrodynamic efficiency.
Our commitment to constant technological advancement has earned us 69 patents (including 5 major invention patents) and 2 software copyrights. Furthermore, we are certified across multiple strict operational standards:

Continuous R&D aimed at higher efficiency, smart diagnostics, and reduced operating costs.
We are integrating magnetic bearing technologies with high-speed centrifugal vapor compressors. This eliminates mechanical contact, gear friction losses, and oil lubrication requirements, allowing for clean, oil-free steam compression suitable for pharmaceutical crystallization.
Researching new polymer-ceramic matrices and plasma spraying technologies for impellers. These specialized coatings prevent high-temperature scaling and protect the rotor profile against wear when processing aggressive chemical vapor mixtures.
Utilizing artificial intelligence models to predict scaling patterns and thermodynamic changes inside MVR loops. Operators can adjust temperature differentials remotely, preventing sudden surges or compressor stall issues.
Clear, technical answers to common queries regarding MVR systems and compressor designs.
The main selection parameters include the required saturation temperature rise (which determines the pressure ratio), the suction volumetric flow rate, the corrosive nature of the vapors (chlorides require Duplex or Titanium construction), and the sealing requirements. Roots compressors are typically selected for low flow, high temperature rise applications, whereas single-stage centrifugal compressors are ideal for larger flow rates with moderate temperature rises.
We implement advanced double or triple mechanical seal packages. Depending on the process steam characteristics, we apply water-injection cooling, gas-buffered seals, or dry gas seals. This prevents compressed steam from leaking into the atmosphere and keeps water vapor out of the bearing lubricating system.
An MVR system recycles the latent heat of vaporization from the waste steam. Instead of venting or condensing this steam using external cooling water, a compressor increases its heat content so it can be reused. This cuts down fresh steam consumption to near zero, significantly lowering total carbon footprints and operating expenses.
