Origin of materials
Explanation on use of conflict materials

Our company does not activate any direct imports of conflict materials related to the Dodd-Frank Wall Street Reform and Consumer Protection Act, which came into force in 2010.

Processing solutions from the idea through to series production
We are dedicated to manufacturing innovative products. We, as an extremely innovative company continually pursue new solutions for practical application. Safety, efficiency and usability are our guidelines.

Thorough inspection
When stipulating the appropriate component for each application the components and materials are subject to strict material and hardness tests. Everything which is created on the virtual drawing board is carefully assembled with great attention as a proto type and thoroughly tested. Measuring devices and components for measuring instruments for example are tested for functionality in climate chambers under extreme climatic conditions.

After successful test the proto type is integrated into the system with a further test step – for example an SF6 service cart is finally tested thoroughly in our test centre.

Customer orientated troubleshooting
Our engineers and technicians are always searching for user friendly solutions tailored to customer requirements. For development we attach great importance to close collaboration with our customers since user feedback flows directly into our product development. Thus we make use of customer problems for practical solutions for professional and sustainable SF6 gas handling.
