We are deeply grateful for your generous support and warm encouragement. We sincerely thank you from the bottom of our hearts. Taking this opportunity, we will once again return to the spirit of our founding and strive to improve our services even further through social contribution projects. We look forward to your continued patronage. Now, we have introduced various VOC deodorization devices to the world. TESSHA Corporation (formerly known as Railway Vehicle Industry Co., Ltd.) was established in 1946 for the purpose of manufacturing railway vehicles. Subsequently, with the advancement of motorization, we expanded our business into the field of air pollution control, launching groundbreaking environmental conservation products, including the development of catalytic mufflers for automobile exhaust gas and catalytic deodorization devices for factory exhaust gases. To address all environmental issues, we not only tackle odor problems with deodorization devices but also resolve all sound-related issues through noise and soundproofing measures. If you have any concerns regarding odors or noise, please feel free to contact us.
