So why is it essential to utilize energy management systems?
- In production lines, with the help of continous measurement we have the opportunity to define our consumption (both for the production and stalling periods). Very often we experience, that the consumption is unexpectedly high in stalling periods (the PLC programs do not shut down the whole production unit in case of stalling; there is still heating in he building).
- Another very common problem, when multiple production lines produce the same product, and for some reason there is still significant difference between the consumptions. This is resulted from the inappropriate maintenance of the production lines, and by discovering the problem too late (because of the lack ofutilizing any measurement device, we can not track the power demands, like increased consumption of an engine). Often we only realize the problem when it’s too late, and the production device not possible to repair any more, causing highly increased cost per product.
- With continous measurement of the technology, we can define the weak points, where we are able to save energy with specific changes (with the usage of low-consumption frequency regulators for example). It is also important to find out the time it takes for the investment cost to return. Very often this time interval is not determined precisely, which will result cancellation of the projects, because of the lack of any installed measurement-system. The inefficient production will continue without the knowledge of the company.
