Less downtime, no paint particles in the environment, and low energy consumption. A sustainable solution for the long term.
Water authorities and municipalities have been facing the problem of rusting motors for years. This is something Jan Bakker, Technical Manager at Kolmer Elektromotoren, also recognizes.
“Not a small issue,” he says. “The Netherlands has more than 5,000 pumping stations. And that doesn’t even include all the pumps in sewer and water systems. These installations often run 24/7 and are continuously exposed to rain, wind and sun.”
Those conditions take their toll. “In many electric motors, the paint layer starts to peel. The result is corrosion, downtime and higher maintenance costs. And just as important: paint particles ending up in the environment. That’s something you want to avoid. That’s why we were increasingly asked whether there is a solution that really works.”
Kolmer developed a coating to address this. “The goal was clear,” Jan explains. “A tough, wear-resistant and safe solution.”
The ultra-thin coating penetrates through the paint layer and bonds directly to the metal of the motor housing. Dirt and moisture don’t stand a chance, even in case of damage. The result is a permanently protected motor, without corrosion or flaking paint.
In addition to lifetime, energy efficiency is essential. That’s why Kolmer applies the coating to robust electric motors from Cantoni in Poland. These 100% European motors combine high efficiency with a high power factor, resulting in lower energy consumption. Short supply chains help keep the CO₂ footprint low. With around 20,000 motors in stock in the Netherlands, they are quickly available and can be adapted to any application.
At the Vissering pumping station in Urk, Kolmer supported the selection of energy-efficient motors. Water Authority Zuiderzeeland confirms that these motors contribute to energy savings and the sustainability of the pumping station.
