Measuring energy enables to visualize waste and loss of energy, and it supports energy saving activities.

1) For monthly result management2) For departmental control of energy usage

3) For recording and managing energy data

•Obtain a basic unit by using energy usage and production quantity in a production line and facilities, and analyze it as a productivity index;

1) Analyze energy waste and loss in production line

2) Be aware of facility operation3) Analyze for operation improvement, such as production

process improvement and efficient operating condition

Don’t overlook waste of energy!!

Unit control helps to improve productivity.
