In recent years, heat storage deodorization devices have become popular, but do they really meet production needs? When it comes to deodorization devices, there are various treatment methods available. Among them, more companies are choosing the "catalytic type," which has the highest purification rate in combustion methods, with operating costs less than half compared to direct combustion, and is also low in installation costs and has a shorter lead time than heat storage types, making it suitable for various locations. As fuel costs rise, the advantages of catalytic deodorization devices, which can reduce fuel consumption and maintenance costs, are becoming increasingly prominent. Compared to heat storage types, these devices are smaller and have a quicker startup time, making them ideal for production lines that do not operate 24 hours, test plants, and research and development use. Therefore, we are offering a set of three documents that explain the features of catalytic deodorization devices! Please take a look at them as reference materials for your introduction considerations. Additionally, feel free to consult us regarding VOC measures or any odor-related issues. 【Overview of the 3-Book Set】 ■ Comprehensive Product Catalog (Includes our deodorization devices from heat storage to catalytic types) ■ Basic Knowledge for Introducing VOC Treatment Devices (Includes information on emission regulations and how to choose devices) ■ Comparison Table of Deodorization Methods (Comparison with combustion, plasma, adsorption, etc.) *You can view them immediately from "Download."

**[Problems Faced by Company B]** The nearby residents were concerned about the odors leaking from the factory. The source of the odor was the VOC gases generated during the resin molding process. Although a treatment system had already been installed, the new production line made it impossible to keep up with the processing, leading to the consideration of adding another treatment system. However, a fundamental issue arose: there was no available space for installation, including the work area. The possibility of installing it outside the building was also considered, but that was not feasible due to regulations such as the Green Space Act. **[Benefits of Implementation]** By suspending the system from the ceiling, there were no issues with floor space. Additionally, it was equipped with a function to utilize exhaust heat to warm the workspace during winter. VOC treatment was achieved in a compact manner, and energy savings were also realized. The customer was very satisfied. ● For more details, please download the catalog or contact us.

**[Problems Faced by Company A]** They were concerned about the deterioration of the workplace environment for employees caused by VOCs generated during the molding and coating drying processes of resin products. While combustion-type treatment devices are the most effective for VOC treatment, they struggled to find a device that met the condition of not threatening the 1.5m wide workspace between the dryers. Even when devices that could fit in the space were available, they often lacked sufficient processing capacity, leading to ongoing challenges. **[Implementation Effects]** The compact catalytic deodorization device, which is easy to operate with a touch panel, achieved a space-saving design of 120cm in width, 50cm in depth, and 70.5cm in height, while providing a processing capacity of over 3N?/min and a VOC removal efficiency of over 98%. After installation, the solvent odor that had been lingering in the workspace was reduced, creating a safer working environment. Employees have expressed high satisfaction, stating, "It has become easier to work" and "The solvent odor no longer clings to my clothes." ● For more details, please download the catalog or contact us.

The "catalytic deodorization device" is a system that oxidizes combustible substances, VOCs, and odors in exhaust gas by bringing them into contact with air through a catalyst, resulting in odorless and harmless emissions. Since it can initiate oxidation reactions at low temperatures (300°C to 350°C) below the ignition point, it consumes about one-third the fuel for preheating compared to direct combustion deodorization devices. Additionally, it is equipped with a built-in heat exchanger, and by adding a secondary heat exchanger, significant fuel savings can be achieved. 【Features】 ■ High deodorization efficiency with high-performance platinum-based catalysts ■ Low generation of nitrogen oxides, enabling low NOx operation ■ Negative pressure structure in the exhaust gas flow path within the device to prevent odor leaks ■ Compact integrated design with low flow resistance, reducing power consumption *For more details, please refer to the PDF document or feel free to contact us.
