Sealed Surface Conversion System

Products treated with nsd tupH are ideal for extreme ambient conditions and hygiene requirements.


nsd tupH Sealed Surface Conversion System

NORD DRIVESYSTEMS now has an answer for the requirements of drive technology for extreme environment conditions in the variety of products with which you are familiar for standard geared motors – however, with the resistance of stainless steel and an outstanding price/performance ratio. The aluminium surface is coated with a special process to make it extremely durable. Together with a special sealing process, this layer is up to 7 times harder than the basic aluminium material and up to 1000 times harder than paints and lacquers – and so has very low wear characteristics. It therefore provides unique protection against corrosion, as it is not a paint layer which can detach or flake off.
