“Previously, with older motor technology, we have experienced damage to motors and bearings due to the electric currents generated in the older rotor designs,” van Belzen says. An independent Analysis Engineer examined the motors, drives and pumps, and verified the robustness of the technology.
“Everything was working as expected, and there was no damage from electrical fields and currents. This is important for the 20-30 year life expectancy that we have for this equipment,” van Belzen explains.
“We are required to deliver water to our customers with absolutely no interruption in supply,” says Dietrich Houtepen, the Production Engineer at the new Nieuwdorp plant. “The access to fresh water is a civil right required by law in the Netherlands. Therefore, we can take no risks when implementing new technology.”
Ultimately it is his day-to-day responsibility to ensure stations run smoothly without any problems and the continuous supply of the water is guaranteed in the region. “Downtime, meaning time which we cannot actually deliver drinking water to our customers’ homes in the region, is counted in seconds per year. When we saw ABB’s SynRM package we were confident of the long-term reliability of the technology. It is important when we are selecting equipment that it will run for years without any trouble.”
