• Regenerative Thermal Oxidizers (RTO):

Regenerative Thermal Oxidizers (RTO) are among the most efficient technologies for treating low-concentration, high-volume volatile organic compound (VOC) emissions, and Wuxi Zechuan Environmental Technology Co., Ltd. has mastered this system with exceptional precision. Their RTO units, designed according to German engineering standards, achieve a thermal efficiency of over 95%, drastically reducing fuel consumption compared to traditional incineration methods. The core innovation lies in the dual or multi-chamber ceramic regenerator system, which alternately stores and releases heat, enabling continuous operation with minimal energy input. For instance, at Shanghai Delphi International Storage Battery Co., Ltd., Zechuan installed a large-scale RTO system capable of processing over 50,000 m³/h of exhaust gas containing benzene series and ketones. The system maintained a VOC destruction efficiency above 98% even during seasonal fluctuations in gas composition and flow rate. What sets Zechuan apart is their ability to handle complex gas mixtures that would deactivate catalysts in RCO systems—such as those containing mercury vapor, phosphorus compounds, or halogens—making their RTOs ideal for industries like chemical engineering and metal coating. Additionally, the inclusion of a purge cycle after each heat release phase ensures a VOC removal rate consistently above 95%. The system’s automation, safety features (including anti-backfire design), and modular construction allow for rapid installation and easy maintenance. These attributes were crucial in a project for SK Hynix-STMicroelectronics Co., Ltd., where downtime was minimized and compliance with strict EU emission limits was guaranteed. Zechuan’s RTOs are not just pollution control devices—they are intelligent, energy-saving, and future-ready systems that align with global decarbonization goals.

• Advanced Adsorption Treatment Devices:

Wuxi Zechuan Environmental Technology Co., Ltd. excels in developing advanced adsorption treatment devices, particularly activated carbon adsorption towers, tailored for low-concentration VOC removal in sensitive environments like semiconductor and electronic manufacturing facilities. These systems utilize high-performance granular activated carbon and activated carbon fiber, offering superior adsorption capacity and regeneration efficiency. A prime example is the deployment of a vertical adsorption tower system at JTEKT Sealing Technology (Wuxi) Co., Ltd., where the facility faced persistent emissions of acetone and toluene from degreasing processes. Zechuan’s customized solution achieved a removal efficiency of over 97% with a compact footprint and low operating cost. The system’s design incorporates automated switching between multiple adsorption beds, allowing continuous operation without interruption. Moreover, Zechuan integrates solvent recovery capabilities into their adsorption systems, enabling on-site regeneration and reuse of solvents—demonstrated in a successful project with Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd., where recovered solvents were reused directly in production, reducing raw material costs by up to 30%. The company also offers hybrid systems combining adsorption with catalytic oxidation (RCO), providing flexibility for varying emission profiles. Their proprietary control algorithms optimize desorption timing and temperature, extending carbon life and minimizing secondary waste. These innovations have earned Zechuan recognition from clients such as Kurita Water Industries and Dürr AG, who value the system’s reliability, scalability, and alignment with circular economy principles. As industries increasingly prioritize green chemistry and resource recovery, Zechuan’s advanced adsorption technology continues to set benchmarks in sustainable waste gas management.
