Drawing upon the Hitachi Group's advanced technologies, we provide systems that support the information society, including semiconductor manufacturing equipment, electronic component processing equipment and electronic devices. Our energy-saving solutions help reduce the environmental impact on our society.
A compressor is machinery that compresses gases such as air and gas. Compressors are used in various places and for various applications in society, and modern society cannot function without compressors. We have an extensive product line-up to satisfy various needs, ranging from the large centrifugal compressors for process use that form the heart of petrochemical plants, chemical plants, and natural gas plants, as well as general-purpose compressors used in automotive applications, electronics, IT, food processing, steel, and other plant lines. We supply products not only in Japan, but also overseas, based on our long experience and advanced technology.
We have a large line-up of pumps for various applications, including pumps for transporting drinking water, rainwater drainage, sewage treatment, and irrigation, as well as high-temperature, high-pressure water supply pumps for thermal power stations and nuclear power stations. We also have extensive know-how in technologies such as construction cost reduction technology, simulation technology, and extending the service life of pumps after installation.
Sewage Treatment Systems
There are various needs in the sewage treatment field that change based on the environment and lifestyles, such as countermeasures against flooding, preserva+A1:AA29ion of public water quality and re-use of water. We are a plant engineering and construction company that offer total solutions for water treatment. We develop systems and products necessary for these as well as provide services of construction, maintenance and operation. We contribute to the preservation of water environments with our leading technologies which are saving energy, saving power and saving space
Drinking Water Treatment Systems
Drinking water supplying system is extremely important for everyday life. We are extensively experienced in and have a history of working with raw water intakes, transmission, water distribution and supply facilities, various chemical dosing, power receiving facility, instrumentation and SCADA system.
Hitachi power semiconductors are applied to a wide range of high-power control applications throughout the world, including IGBTs for EV/HEV inverter systems, high-power inverters (locomotive, OHV drive systems), and alternative energy (photovoltaic inverter and wind turbine converter systems). Hitachi power diodes are also used widely in the automotive industry.
