Tetsudou Sharyou Kougyou Co., Ltd.

We have track record with volatile organic compound (VOC) countermeasure equipment.

We are an equipment manufacturer founded in 1946. We mainly manufacture and sell volatile organic compound (VOC) countermeasure equipment. We do a lot of business with major domestic Japanese companies such as Toppan Printing, Nippon Xeon, Yonex, Otsuka Pharmaceutical, and Nichireki. We have a track record of overseas transactions mainly with Japanese-affiliated companies in China and Thailand. We respond to various needs from small equipment to large equipment. Our lineup of catalytic deodorization system equipment covers processing wind capacities from 1 cubic meter per minute to 500 normal cubic meters per minute. We are focusing on accelerating our overseas expansion and entry into new fields with the target of expanding sales.

Other presentation

[Company strength]
We have a lineup of small-size equipment covering 1 normal cubic meter per minute and 3 normal cubic meters per minute in order to provide intensive support. We provide optimal systems for various conditions for each customer, such as exhaust gas components and wind capacity. Our catalytic deodorization system equipment features high reliability based on the technologies we have been accumulating for many years. We have been supplying equipment to many customers since 1972. 

[Business description]
We manufacture and sell VOC (volatile organic compound) countermeasure equipment. We mainly deal with the fields noted below.
We manufacture and sell silencers for rolling stock and catalyst mufflers.
We manufacture and sell catalytic deodorization system VOC countermeasure equipment from small to large sizes. (Processing wind capacity from 1 normal cubic meter per minute to 500 normal cubic meters per minute.)
We manufacture mainly deodorization equipment with various combustion systems. These include catalytic deodorization equipment and direct combustion deodorization system equipment from small to large sizes. (Processing wind capacity from 1 normal cubic meter per minute to 500 normal cubic meters per minute.) We also manufacture regenerative deodorization equipment.
Small equipment in particular can effectively support local exhaust and help improve the work environment.

VOC processing equipment manufacturing

[Strength of products/technologies]
We maintain a high VOC removal rate by using a combustion system. In particular, our catalytic system enables efficient driving. A high removal rate can be achieved if deodorization performance is required. Remote monitoring using Wi-Fi communications is also possible in our small-sized equipment. Our products can be effectively utilized if local ventilation is particularly required. We realized portable equipment by attaching casters.

[Representative's message]
Manufacturers in Japan have recently tended to flow out to foreign countries. Domestic demand decreased as a result, and so competition became severe. We hope to take on the challenge of new projects by making use of combustion technology, as well as expanding our business scale including overseas transactions. We hope to construct a wide network and improve our corporate system in order to accurately support market needs and create new business chances.

[Company structure for market development/overseas expansion]
We have responded to the customer every time we receive an inquiry. From now on we hope to expand our support to Southeast Asian countries, and also Taiwan. A sales staff member and designer will take charge of each business item. Installation will be conducted by a local enterprise, and we will dispatch staff for service.
