Inside a synthetic fiber plant (1960s)
Japan's manufacturing industries were decimated during World War II, but from about 1949, they began to recover at a rapid pace, particularly the textile industry. Kenzaisha, which had gained a reputation for installing high-quality, low-cost HVAC systems in textile plants, began to expand its business in this field. By 1952, it had received orders for major construction projects from 8 of the 10 largest textile companies in Japan.
From about 1955, the use of petroleum-based synthetic fibers such as nylon and polyester became increasingly common in Japan. The production process at synthetic fiber plants required precise control of air flow, temperature, humidity, pressure and other elements, which necessitated much more sophisticated HVAC systems than those used in cotton and rayon spinning. With its experience in textile HVAC systems and its pursuit of the latest technology, Kenzaisha by 1970 had secured a major share of the market for synthetic fiber plant HVAC systems. From this time onward, the Company became closely identified with industrial HVAC systems, a field that required far more advanced control technology than building HVAC systems.
Meanwhile, since 1950, the Company had also delivered numerous air-conditioning systems to factories in industries such as pharmaceuticals, precision machinery and film. At these plants, air-conditioning systems that could maintain a high level of air purity were needed to prevent damage to products. Although cleanrooms did not come into widespread use in Japan until the second half of the 1960s, Kenzaisha was already handling dust-free installation of air-conditioning ducts as early as 1954. In 1967, the Company installed a Class 100 cleanroom at a film plant, and in 1973 it installed a Class 100 germ-free operating room and biological cleanroom at the Medical Department of Kinki University.

In the 1970s, integrated circuit technology developed rapidly, and semiconductor plants requiring sophisticated cleanrooms were built one after another. Based on our technical expertise gained through constructing cleanrooms and precision air-conditioning systems for synthetic fiber plants, we provided equipment that guaranteed a high level of purity to many electronics manufacturers. In the 1980s, Taikisha also began supplying semiconductor cleanroom systems to customers in the United States and Southeast Asia, and gained attention as a pioneer in the field.
