Water used in various industries plays a decisive role in product quality and operation management in the ultra-precision industry. As such, ultra-precision industries such as semiconductors require a large amount of ultra-pure water or de-ionized water, and refer to water in areas with purity of PPB, which is usually 1/1000 unit of PPM based on any material. We are accumulating technologies that can provide services including purchase, construction, quality control, commissioning, and Guarantee.
