Seibu Giken Co Ltd is a Japan-based company mainly engaged in the manufacture, sale, and provision of installation and other services for desiccant dehumidifiers and volatile organic compounds (VOC) concentrators. Desiccant dehumidifiers dehumidify air by adsorbing moisture inside a honeycomb using adsorbent materials such as silica gel or zeolite. Since air does not need to be cooled, it is characterized by its ability to dehumidify even at low temperatures or in low dew-point environments where there is little moisture in the air. VOC concentrators selectively adsorb volatile organic compounds, collectively known as benzene and toluene, which cause air pollution generated from paint, into the VOC concentrator rotor to make it possible to detoxify exhaust gas emissions by selectively adsorbing VOC concentrating rotors. Product-related services is engaged in the provision of installation, maintenance, and rotor replacement services.
