Instead of conventional solenoid valves we use reliable stepper motors from the automotive industry for our valve units. These valves have been invented and developed by BONNEL and successfully tested since 2008 in real waste water treatment plants. Now this technology is more and more used by other companies, too.

Why stepper motors?

First, they consume energy only during opening or closing of the valve, therefore saving 95% of energy when compared to conventional valves. That is about 90kWh per year or 15€, and the trend is rising.
Secondly, our valves are, due to the smoother and slower movement, much quieter than solenoid actuated valves.
