Responding to the Needs of Our Customers

Enhance your competitiveness by reducing total cost

By repeating each PDCA cycle process, we continually provide appropriate maintenance services to our customers.

Maintain equipment quality in order to raise operation rates

When it comes to scheduled maintenance periods and procedures, an optimal balance between cost and quality is imperative. While ensuring that safety is the top priority, we design maintenance methods and schedule maintenance periods that serve to raise equipment operation rates in order to maximize profits.

The cultivation of our engineers' talent has resulted in a unique maintenance system

Our engineers have developed expertise on both sides of E &M (Engineering and Maintenance); CEC's human resources are always on hand to provide high value-added solutions and to support every aspect of your maintenance needs.

By maintaining sufficient capacity, we can support to minimize loss in the event of an emergency.

A minimal maintenance system may be adequate during normal operation, but ample capacity and flexibility are needed to cope with unexpected situations and unanticipated problems. In order to minimize production loss in the case of an emergency, we establish a shift-work system capable of responding to a full range of possible scenarios.
