Detailed information for simplifying your processes
Your VdS-Approval – why all this?
Many defects on and in the complex WES combinations cannot be detected with the naked eye – but do in an emergency demolish the life-saving extinguishing process.
VdS ensures the long-term reliability of your developments
- from microscopic investigations of the dreaded "tip breakage" to pressure and flow loads for valves with large nominal widths,
- with clearly confirmed effectiveness under various laboratory conditions including insensitivity to pressure fluctuations, environmental influences, etc.,
- up to the practical proof of your full extinguishing success in exact replicas of e.g. office complexes or production machines.
So you can clearly demonstrate to your buyers + also to authorities, consultants and insurers: My system will work when it counts. Even after decades. Even under the toughest conditions.
For sure.
