Nishishiba Electric Co., Ltd.
Nishishiba Electric Co., Ltd. develops and manufactures products related to marine electrical systems as well as generator and industrial systems that support social infrastructure.
Previously, in the testing process for fully closed (IP44*) large generators to be installed on vessels, industrial water was used as the cooling water, which was treated after use as industrial wastewater. To improve, we introduced a new cooling tower as a cooling water circulation system, and we changed to a method of circulating and reusing cooling water. As a result, we reduced the amount of water used by approximately 5,500 m3 annually, which is equivalent to the amount of water in approximately ten 25-m swimming pools.
We will strive to conserve water resources by using water efficiently.
