--- Unmatched Expertise in Waste Gas Treatment ---

• Decades of Experience and Innovation:

With more than three decades of dedicated research and development in environmental protection equipment, Wuxi Zechuan Environmental Technology Co., Ltd. has built a solid foundation of technical expertise that sets it apart from competitors. The company’s deep-rooted collaboration with Tongji University—a globally recognized leader in environmental engineering—ensures that its innovations are not only scientifically sound but also at the forefront of international standards. This academic-industrial synergy enables Zechuan to develop advanced waste gas treatment systems such as RTO (Regenerative Thermal Oxidizer), CO (Catalytic Oxidizer), and solvent recovery units that deliver superior performance even under complex operating conditions. For instance, in a recent project with Ajimon (Anqing) Technology Development Co., Ltd., Zechuan successfully implemented an RTO system capable of handling large volumes of low-concentration VOC emissions from pharmaceutical manufacturing processes. The system achieved a VOC removal rate exceeding 98%, meeting stringent local emission regulations while reducing energy consumption by up to 40% compared to conventional incineration methods. Furthermore, Zechuan’s ability to customize solutions based on real-time process data and fluctuating gas compositions demonstrates its adaptability and innovation. Their proprietary design approach, aligned with German engineering standards and validated through rigorous testing, ensures long-term reliability and operational efficiency. These capabilities are not just theoretical—they are proven in practice across more than 100 successful projects nationwide, reinforcing Zechuan’s reputation as a trusted innovator in the field.

• Turnkey Services from Design to Implementation:

Wuxi Zechuan Environmental Technology Co., Ltd. stands out in the industry by offering end-to-end turnkey services that cover every stage of a waste gas treatment project—from initial consultation and system design to equipment procurement, construction, installation, commissioning, personnel training, and final compliance acceptance. This holistic approach eliminates the need for clients to coordinate multiple vendors, significantly reducing project timelines and risks. A prime example is the collaboration with Murata New Energy (Wuxi) Co., Ltd., a major player in lithium-ion battery production. Facing increasing regulatory pressure due to high-volume organic solvent emissions during electrode coating, Murata partnered with Zechuan to deploy a fully customized RCO (Regenerative Catalytic Oxidizer) system. Zechuan’s team conducted detailed site assessments, modeled gas flow dynamics, and designed a modular system that seamlessly integrated into existing production lines. The entire project was completed within 12 weeks, including on-site installation and operator training. Post-commissioning, the system consistently maintained VOC removal rates above 99%, enabling Murata to achieve full regulatory compliance and avoid potential fines. Moreover, Zechuan’s pre-sales support team ensured rapid response and tailored recommendations, while their after-sales service provided prompt maintenance and remote diagnostics via IoT-enabled monitoring. This seamless integration of design, execution, and ongoing support exemplifies how Zechuan delivers not just equipment, but sustainable, future-proof environmental solutions that align with clients’ long-term operational goals.

--- High-Quality Products and Competitive Advantages ---

• State-of-the-Art Equipment and Technology:

Wuxi Zechuan Environmental Technology Co., Ltd. leverages cutting-edge technology and internationally recognized engineering standards to produce high-performance waste gas treatment systems. All core equipment—including RTOs, COs, activated carbon adsorption towers, and scrubber systems—is designed and manufactured according to German industrial standards, ensuring precision, durability, and optimal thermal efficiency. One notable example is the RTO system installed at SK Hynix-STMicroelectronics Co., Ltd., a leading semiconductor manufacturer in China. The facility faced challenges with volatile organic compounds emitted during photolithography and cleaning processes, which required a solution capable of handling variable gas loads and preventing catalyst poisoning. Zechuan delivered a dual-chamber RTO system featuring ceramic regenerators with advanced heat storage cycles and a purge mechanism that maintains VOC removal efficiency above 95% even during load fluctuations. The system operates with a thermal efficiency of over 95%, significantly reducing natural gas consumption. Additionally, Zechuan’s use of OEM partnerships with Japanese and South Korean firms ensures that their equipment meets the exacting quality requirements of multinational corporations. Their production facilities in Wuxi are equipped with automated welding robots, CNC machining centers, and real-time quality inspection systems, guaranteeing dimensional accuracy and structural integrity. Every unit undergoes triple inspection—self-check, peer review, and specialized testing—before delivery. This meticulous attention to detail results in a product qualification rate exceeding 99.5%, making Zechuan’s equipment not only reliable but also cost-effective in the long run due to reduced downtime and maintenance needs.

• Commitment to Quality Assurance and Sustainability:

At Wuxi Zechuan Environmental Technology Co., Ltd., quality is not just a standard—it’s a culture. The company holds certifications in ISO9001 (Quality Management), ISO14001 (Environmental Management), and OHSAS18001 (Occupational Health & Safety), reflecting its unwavering commitment to operational excellence and sustainability. These certifications are backed by internal audit systems and continuous improvement protocols. In addition, Zechuan has secured over 20 utility model patents, including innovations in solvent recovery systems and low-pressure drop adsorption units, which enhance energy efficiency and reduce secondary pollution. A standout case is the solvent recovery system deployed at Suzhou Sumitomo Bakelite Co., Ltd., a chemical manufacturer producing high-purity resins. The system uses Zechuan’s patented adsorption purification technology, achieving a recovery rate of 99.2% and producing solvents with less than 0.5% water content—ideal for reuse in production. This not only cut raw material costs by nearly 30% but also eliminated the need for hazardous waste disposal. Furthermore, Zechuan’s biological deodorization systems, developed using microbial strains acclimated by Tongji University, have been successfully implemented in wastewater treatment plants across Jiangsu and Zhejiang provinces, achieving odor removal rates of over 98% without generating harmful byproducts. By prioritizing eco-friendly materials, energy-efficient designs, and closed-loop recycling, Zechuan ensures that its solutions contribute positively to both corporate ESG goals and broader environmental sustainability efforts.

• Successful Projects with Renowned Clients:

Wuxi Zechuan Environmental Technology Co., Ltd. has earned a stellar reputation through its extensive portfolio of successful projects with some of the world’s most reputable industrial and pharmaceutical companies. Among these, the implementation of a multi-stage waste gas treatment system at AstraZeneca Pharmaceutical Co., Ltd. stands out as a benchmark case. The pharmaceutical giant required a solution to manage complex VOC emissions from API synthesis and packaging operations, where mixtures of benzene series, ketones, and halogenated compounds posed significant challenges. Zechuan designed a hybrid system combining RCO for catalytic oxidation and a chemical scrubber tower for acid-gas neutralization. The system achieved a consistent VOC destruction efficiency of 99.7% and met all EU and Chinese emission thresholds. After six months of operation, AstraZeneca reported zero non-compliance incidents and praised Zechuan for their technical responsiveness and seamless integration. Another landmark project was with Guangzhou Toyota Motor Co., Ltd., where Zechuan installed a custom RTO system to treat paint shop emissions from automotive body painting lines. The system handled over 100,000 m³/h of air volume with stable performance, reducing NOx emissions by 60% and saving the client approximately ¥2 million annually in energy costs. These successes are not isolated; they reflect a consistent pattern of delivering high-impact, scalable solutions across diverse industries, including electronics (e.g., JTEKT Sealing Technology), food processing (e.g., Shanghai Bright Dairy), and heavy machinery (e.g., XCMG Group).
