Modernization of an existing line, a machine or a project of a new device equipped with control systems requires adjusting the characteristics of mechanical systems to the current or expected parameters. What becomes necessary is proper selection of drive systems (transmissions, motors, starting systems, frequency converters) as well as power supply systems for these drive systems (cable diameters, safety devices, temperature control). Based on our experience or the experience of companies we cooperate with, while executing modernization projects we provide high quality and reliability of the prepared mechanical systems, which meet specific requirements of the industry.
