Signalling under hygienic conditions


Hygienic Design

A hygienic design refers to the design of machinery and components that are easy to clean and maintain a sanitary condition for use in areas where bacteria or other harmful detergents might cause undesirable processing issues. The aim is to prevent design deficiencies that promote hygiene-related hazards or the risk of infection.

The CleanSIGN signal tower was specially developed and constructed by WERMA for use in cleanrooms, the food industry and areas with strict hygiene requirements.
