• Regenerative Thermal Oxidizers (RTO):
Regenerative Thermal Oxidizers (RTOs) are at the forefront of modern waste gas treatment, offering unparalleled efficiency in controlling low-concentration, high-volume VOC emissions. Wuxi Zechuan Environmental Technology Co., Ltd. designs and manufactures RTO systems that adhere strictly to German engineering standards, ensuring thermal efficiency of up to 95% or higher. The core principle involves heating organic waste gases to temperatures above 750°C, where VOCs undergo complete oxidation into carbon dioxide and water vapor. The heat generated during combustion is captured by ceramic regenerators—typically two or more chambers—that store thermal energy and preheat incoming gas, drastically reducing fuel consumption. Each chamber cycles through heat storage, heat release, and purge phases, with the purge step ensuring VOC removal rates exceed 95%. Zechuan’s RTO systems are particularly effective in industries such as coating, printing, chemical engineering, and electronics, where gas composition varies frequently or contains catalyst-poisoning elements like mercury, tin, phosphorus, or halogens. A standout case involved Shanghai Delphi International Storage Battery Co., Ltd., where Zechuan installed a dual-chamber RTO system to treat benzene series compounds emitted during battery casing painting. The system maintained consistent performance even during peak production shifts, achieving a 99.2% VOC destruction efficiency and enabling the facility to pass stringent environmental audits. Furthermore, Zechuan’s RTO units feature automated control systems, fail-safe safety mechanisms, and remote monitoring capabilities, minimizing operational risks and maximizing uptime. With proven track records across over 100 projects nationwide, Zechuan’s RTO technology exemplifies how innovation in thermal oxidation can drive both environmental compliance and industrial sustainability.

• Pharmaceutical and Chemical Industries:
The pharmaceutical and chemical industries face some of the most challenging waste gas profiles due to the presence of complex, toxic, and volatile organic compounds such as benzene, toluene, acetone, and chlorinated hydrocarbons. Wuxi Zechuan Environmental Technology Co., Ltd. has developed highly specialized solutions tailored to these sectors, combining advanced RTO systems with targeted scrubbing and adsorption technologies. In one landmark project, Zechuan partnered with Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd., a Tier-1 supplier for international drug manufacturers, to address emissions from API (Active Pharmaceutical Ingredient) synthesis processes. The plant produced variable concentrations of methanol, ethyl acetate, and dimethylformamide (DMF)—substances that could deactivate conventional catalysts. Zechuan designed a hybrid system integrating a high-efficiency RTO with a multi-stage activated carbon adsorption tower and a chemical scrubber using sodium hypochlorite solution. This configuration ensured a VOC removal rate of over 98.5% and prevented catalyst poisoning. Similarly, for Ajimon (Anqing) Technology Development Co., Ltd., a specialty chemical producer, Zechuan implemented a custom RCO (Regenerative Catalytic Oxidizer) system that operated efficiently at lower temperatures (around 300°C), reducing energy costs by 40% compared to traditional incineration. The system was also equipped with real-time monitoring and automatic adjustment features, allowing it to adapt to changing process conditions. These cases highlight Zechuan’s ability to deliver flexible, scalable, and compliant solutions for industries where regulatory scrutiny is intense and operational continuity is critical. By aligning technological innovation with industry-specific challenges, Zechuan continues to set benchmarks in environmental protection within the pharmaceutical and chemical sectors.
