• Turnkey Services from Design to Implementation:

At Wuxi Zechuan, we deliver end-to-end turnkey solutions that seamlessly integrate every stage of project execution—from initial concept design and technical consultation to equipment procurement, on-site construction, installation, commissioning, personnel training, and final compliance acceptance. Our deep expertise in VOCs control and treatment enables us to tailor systems that meet both regulatory standards and operational demands. For instance, in collaboration with AstraZeneca Pharmaceutical Co., Ltd., we designed and implemented a custom RTO system capable of handling fluctuating organic loadings from multiple production lines. The system achieved a VOC removal efficiency exceeding 98%, ensuring continuous compliance with China’s National Emission Standards for Air Pollutants (GB 16297-1996). Similarly, for Murata New Energy (Wuxi) Co., Ltd., a global leader in lithium-ion batteries, we provided a fully integrated RCO + activated carbon adsorption recovery system that not only reduced emissions but also enabled solvent reuse, cutting raw material costs by over 30%. These projects exemplify our ability to combine engineering precision with real-world performance, delivering sustainable, scalable, and cost-effective outcomes.

• 30 Years of Experience in Environmental Protection Equipment:

With over three decades of focused R&D and manufacturing experience in environmental protection equipment, Wuxi Zechuan has built a reputation for reliability, innovation, and long-term performance. Our foundation lies in close collaboration with Tongji University, one of China’s top engineering institutions, which provides us with cutting-edge research insights and technological validation. This partnership has led to the development of proprietary designs such as the high-efficiency ceramic regenerator used in our RTO systems—engineered to withstand thermal cycling while maintaining heat recovery rates above 95%. Our production processes adhere strictly to German industrial standards, ensuring consistency and durability. Each unit undergoes a rigorous three-tier inspection system: self-inspection, mutual inspection, and specialized testing, guaranteeing a product qualification rate of over 99.5%. Furthermore, our OEM partnerships with companies from Germany, Japan, and South Korea have driven us to continuously upgrade our designs to meet international quality benchmarks. This deep-rooted technical heritage allows us to confidently serve clients across diverse sectors—from semiconductor manufacturing to pharmaceuticals and automotive coating—knowing that our equipment performs reliably under demanding conditions.

• One-Stop Intimate Solutions for Clients:

Wuxi Zechuan stands out by offering truly personalized, one-stop service solutions delivered by a team of senior engineers and field specialists who understand the unique challenges of each industry. Whether it’s a complex multi-stage scrubbing system for a petrochemical plant or a compact RTO for a small electronics manufacturer, our team conducts detailed site assessments and process simulations to ensure optimal system integration. For example, at Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd., we designed a hybrid RTO-Scrubber system that addressed both high-volume low-concentration VOCs and acidic byproducts generated during synthesis. By combining thermal oxidation with chemical absorption, we achieved a combined removal efficiency of 99.2% while minimizing maintenance downtime. Our ability to customize solutions extends beyond hardware—we also provide full-scale digital twin modeling and remote monitoring integration, enabling predictive maintenance and real-time performance tracking. This holistic approach ensures that our clients receive not just equipment, but a complete operational ecosystem that evolves with their needs, reducing total cost of ownership and enhancing sustainability.

• Robust After-Sales Support and Maintenance Services:

Our commitment to excellence doesn’t end at delivery. Wuxi Zechuan offers a comprehensive after-sales service framework that includes pre-sales consultation, customized design support, professional on-site installation, and rapid response maintenance. We operate a 24/7 technical hotline and maintain regional service centers across Jiangsu, Zhejiang, and Shanghai to ensure timely intervention. In one notable case involving SK Hynix-STMicroelectronics Co., Ltd., our team responded within 4 hours to a sudden RTO combustion chamber temperature fluctuation, diagnosing a sensor calibration issue via remote diagnostics and dispatching a technician within 12 hours—minimizing production disruption. Our maintenance protocol includes scheduled inspections, performance audits, and annual system optimization reports. Additionally, we offer remote monitoring platforms that track key parameters like flow rate, temperature, and pressure in real time, alerting clients before potential failures occur. This proactive approach has helped clients reduce unplanned downtime by up to 60%. With more than 100 successful projects completed and a customer retention rate exceeding 85%, our after-sales service is not just a support function—it’s a core competitive advantage that builds lasting trust and long-term partnerships.

--- Proven Track Record and Client Success Stories ---

• Partnerships with Leading Global Companies:

Wuxi Zechuan has earned the trust of numerous multinational corporations and listed enterprises, including NNE (formerly NNE Pharmaplan), Dürr AG, Kurita Water Industries, and PM Group—global leaders in engineering and environmental solutions. These partnerships are not merely transactional; they reflect our ability to meet stringent international standards and deliver consistent performance across complex supply chains. For instance, our collaboration with Dürr AG on a large-scale RTO system for an automotive paint shop in Shanghai resulted in a 99.5% VOC reduction and a 40% decrease in natural gas consumption compared to legacy systems. The project was recognized by Dürr’s internal sustainability audit as a benchmark for green manufacturing. Similarly, our work with Global Toyo on a solvent recovery system for a textile dyeing facility achieved a 99.3% recovery rate with ultra-low water content in the recovered solvent, allowing direct reuse in production without additional purification. These collaborations underscore our credibility in serving high-performance, high-compliance environments where reliability and traceability are non-negotiable. Our ISO 9001, ISO 14001, and OHSAS 18001 certifications further validate our adherence to global best practices, making us a preferred supplier for international clients seeking compliant, future-ready environmental solutions.

• Successful Projects Across Various Industries:

From heavy industry to high-tech manufacturing, Wuxi Zechuan has successfully delivered waste gas treatment systems across a wide spectrum of sectors. One standout example is our project with JTEKT Sealing Technology (Wuxi) Co., Ltd., a Tier 1 supplier to major automakers. Facing strict emission limits due to volatile solvents used in rubber sealing production, we installed a custom RCO system with integrated activated carbon fiber adsorption and steam regeneration. The system achieved a 99.1% VOC removal rate and reduced energy consumption by 35% through optimized heat recovery. Another success story involves Guangzhou Toyota Motor Co., Ltd., where we implemented a multi-stage deodorization system combining chemical scrubbing and biological filtration to manage odors from wastewater treatment facilities. The solution reduced hydrogen sulfide levels by over 96% and eliminated odor complaints from nearby communities. In the semiconductor sector, we partnered with Suzhou Sumitomo Bakelite Co., Ltd. to install a vertical activated carbon adsorption tower system that effectively removed trace benzene series compounds from cleanroom exhaust gases, contributing to improved air quality and worker safety. These real-world implementations demonstrate our versatility, technical depth, and proven ability to solve even the most challenging waste gas problems—making Wuxi Zechuan a trusted name in environmental protection across China and beyond.
