Aprotec has been a specialist in modern, customised solutions in automation, process plant and leak testing technology. With a team of around 30 engineers and technicians, Aprotec caters to customers in the automotive and semiconductor industries, mechanical engineering, and vacuum technology sectors, offering a portfolio that ranges from the initial idea to the turnkey system

To achieve this, Aprotec relies on the products and the expertise of Leybold. This collaboration goes deep into areas of application where experience is important.

Michael Landgraf, Managing Director, Aprotec, "It is precisely on this knowledge is the basis of our specialisation advantage over our competitors. Our positioning in the niche ensures not least that. we can react quickly to customer requirements."

Aprotec is therefore a system supplier that offers its customers turnkey systems for customised applications. As a result, these are specially designed for processes and their process environments, such as vacuum, overpressure, temperature, or gases – from laboratory scale to industrial production. Aprotec's strategic goal, however, is to go into series production.

The company is managed by Michael Landgraf and Matthias Roth. The founders, who started their own business in 2015, have been working in the vacuum industry – in process, testing and automotive technology.

Their customers rely on established methods, such as helium leak testing. The proven leak detectors PHOENIX Quadro and PHOENIX Vario with their high detection sensitivities play an important role. In addition to fuel cells, components, transmission and engine components, pharma packaging and battery housings are tested.

The high-tech systems from Aprotec are designed for short cycle times, low tolerances and a high level of safety. This requires high-quality materials and a great deal of engineering expertise is necessary. The solutions are therefore experts with decades of application knowledge – such as for high-temperature systems for the semiconductor industry. In addition to the expertise, it is also used in crystal systems in which the ingots for silicon wafers are produced, the use of the best vacuum pumps – because it is elementary here, to be oxygen-free and to be able to set particle pressures precisely.

Leybold has a high level of experience with crystal-pulling processes and can also supply vacuum pumps suitable for this purpose. The VARODRY dry screw pump is not only attractively priced but also completely oil-free. Thanks to its toothed belt drive, it works without gear oil so that there is no risk of contamination due to oil backflow from the vacuum pump to the vacuum chamber.
