Walasiak GmbH

About us

Knowledge & Experience

The most important start-up capital was knowledge and decades of experience in the field of safety technology in mining and tunnelling industry, scientific work in simulation of climatic conditions underground, expert work in the German mining industry, as well as the examination of technical facilities in industrial and public buildings. A further background is given by the activities as a coordinator for EU research projects and responsible tests on refrigeration machines and components in the context of certification programs.
