Hygienic aluminium drives: economical and corrosion resistant
From 4th to 9th May 2019, Nord Drivesystems will be presenting its portfolio of hygienic drive systems for the food industry at IFFA 2019 in Frankfurt (Hall 9.1, Stand F51). Among other highlights, the company will be exhibiting the innovative nsd tupH surface treatment.
The nsd tupH surface treatment is an outstanding anti-corrosion treatment for gear units, smooth motors, frequency inverters and motor starters in washdown-optimised cast aluminium housings. It produces a protective layer which is permanently bonded to the substrate material and makes gear units with aluminium housings as robust and durable as stainless steel versions.
In contrast to painting or coating, nothing can detach or flake off. Damage remains locally restricted and does not spread. The surface is easy to clean and largely resistant to acids and alkalis. Even the use of high-pressure cleaners or contact with many aggressive media is possible, so that nsd tupH drives are therefore an efficient alternative to painted geared motors or stainless steel versions. In contrast to stainless steel drives offered in only few variants, the nsd tupH surface treatment is feasible for almost all NORD aluminium products. For nsd tupH aluminium drives all DIN and standard components, including drive shafts, are made from stainless steel. The fanless smooth surfaced motors prevent the spreading of germs and run very quietly. They are available as synchronous and asynchronous motors and comply with efficiency classes IE2, IE3 and IE4.
Nord drives with nsd tupH comply with FDA Title 21 CFR 175.300 and are therefore suitable for food applications. They have been successfully tested according to ASTM D714 (blistering), ASTM D610-08 (corrosion), ASTM D1654-08 according to DIN EN ISO 2409 (scratching), ASTM B117-09 according to DIN EN ISO 9227 (salt spray test) and ASTM D3170 (Gravelometer). In addition, their resistance to cleaning agents which are commonly used in the food industry has been confirmed in tests.
Whether for agitating, cutting, conveying or palletising, NORD supplies efficient, durable and flexible drive systems for precise positioning and/or dynamic movement, which are suitable for the stringent requirements for hygiene, reliability and robustness in the food industry. The TCO (Total Cost of Ownership) is always kept in view in the wide range of options for industry.
