Iwaki Factory

New building constructed in 2008 to improve production capacity and accelerate equipment lead times

The Iwaki Factory is a cutting-edge water treatment equipment manufacturing facility, where units that comprise large-scale water treatment plants are standardized at a transportable scale and then shipped as assembled products.

Increasing the proportion of production accomplished in-house has enabled enhanced product quality and reduced on-site assembly work, thereby shortening on-site construction times and cutting costs. A major feature of the factory is the clean room for assembly separate from the general production line, in order to serve semiconductor and medical customers.
