Lightning Strike Solution

Designed to provide high standard potable water, single phase actuators from SIPOS Aktorik play a key role in the scheme’s storm protection solution.

Consideration was given to the fact that lightning could take the WwTW out of operation: actuation technology was therefore required to re-direct water to collection basins that can be emergency operated without power from the network.

Technical specialist for Aarhus Water, Morten Nygaard, said: "We had to use penstocks, gate valves and drives that were 100% reliable, even without power. Grønbech & Sønner delivered the solution that comprises several single phase SIPOS actuators for ON/OFF and modulating service. Equipped with frequency converter, SIPOS actuators have the advantage of having very low starting current, making them ideally suited to Uninterruptable Power Supply (UPS).”
