vonRoll's current hydrants combine the most up-to-date technological knowledge with a treasure trove of many years of experience in order to ensure a safe and reliable extinguishing water supply.
The defining properties of our hydrants are their high level of performance and their ease of installation and use. They are also characterised by a modern design which does not become any less attractive over the decades.
As essential components of an intelligent network, they can be equipped with the Ortomat radio-supported leak detection system to ensure constant leak detection and network monitoring.
