Modernisation of heat treatment equipment control systems

Heat treatment equipment control systems need to be modernised at certain times for reasons that may be quite diverse, such as improving safety of operation, ensuring spare parts availability, improving functionality or improving energy efficiency. In contrast to new heat treatment equipment deliveries, modernisation projects include significant involvement of works on production equipment. Modernisation projects therefore require a specific approach with regard to planning, implementation and especially to risk reduction. This article aims to provide guidance for making the necessary considerations. Legal issues will be discussed as well as consideration of the optimal time for the modernisation in the furnace life cycle. Finally, some examples of typical modernisations will be presented.
