Treotham Automation Hygienic Design Gearboxes

Friday, 29 November, 2013 | Supplied by: Treotham Automation Pty Ltd


Designed and certified according to EHEDG (European Hygienic Engineering & Design Group) rules to ensure good material resistance and cleanability, the Hygienic Design Gearboxes from Treotham Automation meet the stringent requirements of the food and pharmaceutical packaging industries.

With their coaxial, dynamic planetary gearheads available in several different performance classes, the Hygienic Design Gearboxes have been designed to provide robustness, resistance and cleanability.

The gearbox housing is free of edges, dead spaces and gaps that could provide a breeding ground for bacteria or microorganisms or act as dirt traps.

Like its adapter plate, the gearbox housing is manufactured from stainless steel 1.4404/AISI 316L - a low-carbon steel that is approved by the US Food & Drug Administration (FDA) for food contact that offers high resistance to cleaning and washdown fluids such as disinfectants containing hypochlorite or chlorinated alkaline foam cleaners.

All stainless steel surfaces are electropolished with a roughness of either 0.8 µm Ra, as stipulated for food processing applications or 0.4 µm Ra, which is the accepted standard for the pharmaceutical industry.

This surface treatment minimises the risk of product residue adhesion and helps disinfectants or cleaning materials drain off after the allocated exposure time without leaving any residues.

The seals on both the motor and the output side of the gearboxes are made from polytetrafluoroethylene (PTFE). Owing to its hygienic surface properties and non-stick effect, PTFE also conforms to the requirements of the US FDA and is suitable wherever hygienic cleaning is a legal requirement in the manufacturing process.
