Corrosion-resistant surface treatment for aluminium drive units

Nord Drivesystems exhibited its aluminium drive units for the food and beverage industry at Anuga Foodtec. The lightweight, corrosion-resistant gear units, smooth surface motors, frequency inverters and motor starters in wash-down optimised die cast aluminium housings are extremely robust and durable thanks to a special surface treatment: NORD nsd tupH surface protection. For use in demanding environments, NORD offers the extremely effective nsd tupH anti-corrosion treatment for aluminium drive units. With this process, the material is hardened below the surface. The surface treatment creates a protective layer which is permanently bonded to the substrate material. It is based on an electrolytic process and gives aluminium corrosion resistance properties which are similar to those of stainless steel. The scratch-resistant surface is more than seven times harder than untreated aluminium alloy. The drives can easily withstand high pressure steam washing or contact with aggressive media.
