TESSHA List of Products and Services

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." Please feel free to contact us.

TESSHA Corporation's silencers are widely used in diesel trains, hybrid diesel trains, and maintenance vehicles, including those operated by JR companies and third-sector operators. They are also adopted in diesel trains running under harsh conditions in cold regions such as Hokkaido and Tohoku, where their durability and reliability are highly regarded. 【Features】 ■ Widely adopted in diesel trains operated by JR companies and third-sector operators ■ High durability and reliability, ensuring safety even in cold regions ■ Also used in other maintenance vehicles and forklifts *For more details, please download the catalog or contact us.

If too many carbon particles adhere to the demister, it can cause clogging, leading to an abnormal increase in back pressure, which may result in engine overheating or damage to the wire demister. Please pay careful attention to maintenance management. 【Maintenance Management】 - Regularly (every 5 to 10 days of operation) remove the cleaning plug, and while the filter is attached, run the engine at idle to discharge accumulated carbon into a collection bag or similar. - It is also acceptable to use a vacuum cleaner for cleaning. Inspect the demister during each operation, pull it out, and either shake off the carbon or soak it in a neutral detergent solution to wash off the adhering carbon. - Check for cracks in the main body, inlet pipe, outlet pipe, and brackets. - Be careful not to inhale carbon particles during work. ● For more details, please contact us.

This is a simple graphite removal muffler that circulates and grows graphite particles from diesel exhaust gases within the muffler, removing the graphite through the effect of a wire mesh demister. 【Performance】 Carbon contamination reduction rate: over 30% ● For more details, please download the catalog or contact us.

Our catalytic mufflers began with small three-wheeled dump trucks used in tunnel construction during the 1950s and have been adopted in construction machinery such as bulldozers, excavators, truck mixers, and dump trucks, as well as in railway vehicles and forklifts, with their effectiveness widely recognized. 【Features】 ○ High purification efficiency ○ High durability ○ Low back pressure ○ Easy installation ○ Soundproofing effect ● For more details, please download the catalog or contact us.

We would like to introduce examples of TESSHA Corporation's hot air circulation type drying ovens, developed for coater machines and for baking enamel wires. The drying oven for coater machines processes exhaust gases through a catalytic deodorization device. Furthermore, it utilizes those exhaust gases to generate all the heat sources for the drying oven. It is capable of accommodating advanced temperature settings. The hot circulation oven developed for baking enamel wires can adapt to changes in baking conditions depending on the type of wire, while maintaining a uniform temperature balance within the oven. It is also an ideal hybrid single oven equipped with deodorization functionality. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ You can view the "Request for Quotation" from the 【Download】 section.
