NORD DRIVESYSTEMS has developed the nsd tupH anti-corrosion treatment for use in demanding environments with stringent hygiene requirements. The innovative surface treatment, which makes aluminium drives extremely robust and durable, also impressed the Australian company Smalte Conveying Solutions.
The nsd tupH surface treatment from NORD DRIVESYSTEMS provides an outstanding anti-corrosion protection for gear units, smooth surface motors, frequency inverters and motor starters in washdown-optimised cast aluminium housings. By means of a special process, the aluminium surface has similar corrosion resistance properties to stainless steel. It can be easily cleaned and is largely resistant to acids and alkalis.
Even the use of high pressure cleaners or contact with many types of aggressive media is possible, making nsd tupH drives a robust and durable alternative to painted geared motors or stainless steel versions. nsd tupH treatment is available for all NORD products made from aluminium. DIN and standard components, including drive shafts, are manufactured in stainless steel. Fanless motors do not spread germs and are available as synchronous and asynchronous motors with efficiency classes IE2, IE3 and IE4.
Convincing and economical concept
The advantages of nsd tupH drives also convinced Smalte Conveying Solutions, an Australian company which produces conveyor equipment for packaging plants. The company equipped 24 stainless steel conveyors with nsd tupH geared motors instead of expensive stainless steel motors to transport sauces and spreads from a production area to a packaging area and finally to an HMPS packaging machine.
As well as the economic benefits, the technical properties were of primary importance: The requirements for hygiene, cleaning properties and corrosion protection were fulfilled. The washdown motors are mounted with standard flanges and have considerably better thermal characteristics than motors with stainless steel housings.
