Patented service life extension

Since spring 2019 vonRoll Hydro has patented the Anti-Water Hammer System (ANIWAH) and added it as a standard component to the product range. Water hammers, which occur when opening and closing hydrants due to the sudden interruption of the water flow, and piping system vibrations can cause leaks, which in turn compromise the water supply.

Principle of the ANIWAH closing geometry

The new ANIWAH technology ensures a 50% reduction of water hammers and a decrease in the resulting costs. The service life of the systems is increased significantly in the long term. The vonRoll Hydro underground and above-ground hydrants are equipped as standard with the ANIWAH technology.
