Vacuum is required in many industries for very different applications. From vacuum packaging and handling to vacuum clamping, it is a key part of central production processes. Wherever it is used, vacuum technology is always at the core of process infrastructure and usually also involves some expenses, such as machines (vacuum pumps), installations (pipe and line systems), energy (electricity costs) and maintenance. In view of overall economic and ecological efficiency, it is therefore worth taking a closer look at this topic.
Busch’s “5 Elements of Efficiency” – the most important factors in the efficiency of vacuum systems – can serve as the starting point for such an analysis.
The vacuum pump is of course the technical heart of the vacuum system. Its specific design and quality form the foundation for performance and efficiency. These characteristics also largely determine the life cycle costs.
Like most machines, vacuum pumps convert kinetic energy into heat energy during operation. This waste heat can be used with heat recovery systems to significantly improve the energy balance and thus reduce costs.
Vacuum cannot be simply switched on and off like electricity. Even the most powerful vacuum pump needs a certain amount of time to extract a given amount of air. Efficient maintenance of a defined vacuum level requires certain preparations. In order to provide the required vacuum with pinpoint accuracy, the control system of the vacuum system must therefore be optimally matched to the production process. In addition to process stability, it naturally also influences efficiency and not least of all product quality.
A separate vacuum pump is usually installed for each machine or system that requires vacuum. In many companies, however, there are several such units. A central vacuum supply can often lead to considerable savings in energy consumption and maintenance effort. Centralization therefore offers great opportunities for increasing efficiency.
Last but not least: the interaction of the different factors requires a holistic view and systemic analysis. Specific expertise is therefore required to find the optimum efficiency level for vacuum technology.
The most important aspects of an efficient vacuum supply are clearly presented in the brochure “5 Elements of Efficiency: The Vacuum Concept – Efficiency Redefined”. It offers users and system planners a basic orientation for the design and optimization of their vacuum systems. However, we recommend that you seek advice from a vacuum specialist if you want to go into more detail. Busch’s experts offer a Vacuum Audit for this purpose. This includes the analysis of existing equipment and demand, which then serves as the basis for specific recommendations.
