Daicel Safety Systems Inc.

Customer Example

Electric power
consumption reduced by

44%

Daicel Safety Systems Inc., which mainly produces inflators for car airbags, needed to improve the energy efficiency of its businesses activities in line with the Daicel Group’s Responsible Care Basic Policy.

For this customer, one of the issues was improving the energy efficiency and reducing energy use of its cooling water equipment for air conditioning. Kurita Water Industries proposed first removing scales that formed on the heat exchanger of the cooling water equipment and then inhibiting their formation using water treatment chemicals.

Having adopted these proposals, the Company reduced power use 44% by optimizing the heat exchange efficiency of the cooling water facilities, and it was possible to maintain those benefits.

We thought highly of Kurita Water Industries’ proposal because it was appropriate for the issues we faced and it was possible to dramatically reduce energy use as expected.
In the future, we expect to work with Kurita Water Industries to introduce the proposal horizontally throughout the plant and receive other proposals to improve the quality of industrial water.

HGST Japan Ltd.

Customer Example

Electric power
consumption reduced by

90%

HGST Japan, a manufacturer of hard disk drives and other electronic devices, is striving to reduce the environmental impact of its business activities in line with the Western Digital Group,s environmental policy.

For the customer, a continuous reduction in energy use became an issue because it is a designated energy management factory. Kurita Water Industries proposed replacing the membrane filtration equipment with a more efficient one. The previous equipment included a large pump because circulating water returning to the previous stage was necessary due to the original operational condition, but with the new equipment, a small pump can be used because circulating water is not required.

In this case, the proposal was made when we were working to improve energy efficiency, and we adopted it as the improvement was easy to understand and there were substantial benefits. Replacing the old equipment with new smaller equipment made it easier to conduct maintenance and lowered costs, which was helpful.

Improving energy efficiency is an ongoing issue, and we hope for additional proposals for improvements.
