Our commitment to sustainability
The aspect of sustainability is becoming increasingly important to us not only with regard to our products but also in our day-to-day activities. We believe that even small measures can contribute to greater sustainability.
Save Energy
Our two production buildings are heated by the exhaust air from our cast resin vacuum pumps.
Reduce paper consumption
We are saving around 39,000 sheets of paper per year, by digitalized paperless production.
Conserving resources
We have reduced our water consumption by 1,500 m³ due to changes in our production process.
Reduce Waste
We provide all employees with reusable water bottles and thermos coffee cups for their drinks.
