This case underscores Zechuan’s capability to deliver highly customized, industry-specific solutions that balance performance, reliability, and cost-effectiveness.

--- Innovative Technologies for VOC Control ---

• Regenerative Thermal Oxidizers (RTO) Explained:

The Regenerative Thermal Oxidizer (RTO) is a cornerstone of Zechuan’s advanced VOC control portfolio, offering unmatched efficiency and reliability for industrial applications. Engineered in accordance with German standards and built with precision, Zechuan’s RTO systems achieve thermal efficiencies exceeding 95%, significantly reducing fuel consumption while maintaining stable combustion temperatures above 750°C. The core innovation lies in the multi-chamber ceramic regenerator, which alternately stores and releases heat, enabling continuous operation without external heating between cycles. Each chamber undergoes a cyclic sequence of heat storage, heat release, and purge—ensuring VOC removal rates consistently surpass 98%. A standout application was at SK Hynix-STMicroelectronics Co., Ltd., where Zechuan installed a three-chamber RTO to treat waste gas from semiconductor wafer cleaning processes. These gases contained low-concentration volatile organics such as perfluorocarbons and siloxanes, which are notoriously difficult to oxidize. The RTO system successfully handled up to 120,000 m³/h of air volume with a 99.1% destruction efficiency. Notably, the system’s intelligent control interface enabled real-time monitoring of temperature, pressure, and oxygen levels, allowing for predictive maintenance and optimized performance. The client highlighted the system’s durability, with no significant maintenance required in the first two years of operation. This project demonstrates how Zechuan’s RTO technology not only meets but exceeds environmental standards, making it ideal for high-tech industries demanding precision, sustainability, and long-term reliability.

• High-Efficiency Adsorption Treatment Devices:

Zechuan’s high-efficiency activated carbon adsorption towers provide a cost-effective and environmentally friendly solution for treating low-concentration VOC emissions across diverse industries. Leveraging proprietary granular activated carbon and advanced fiber-based media, these systems offer superior adsorption capacity and regeneration efficiency. A key success case is with JieJie Microelectronics (Nantong) Technology Co., Ltd., a Tier-1 supplier for major smartphone manufacturers. The company’s cleanroom facilities produced waste gas containing trace amounts of benzene, xylene, and formaldehyde from solvent-based cleaning agents. Conventional systems struggled with frequent saturation and high operating costs. Zechuan implemented a vertical adsorption tower with integrated steam regeneration and real-time monitoring. The system achieved a 96% VOC removal rate and reduced solvent loss by over 90% through efficient recovery. Moreover, the automated regeneration cycle cut labor costs by 60% and extended carbon life by more than 50%. The client reported a return on investment within 18 months due to lower consumables and improved compliance. This project illustrates how Zechuan’s adsorption technology combines economic viability with high performance, particularly suited for electronics, pharmaceuticals, and printing industries where air purity is paramount and operational continuity is critical.
