CleanSIGN -the LED Signal Tower Specially for Food and Hygiene Areas

Why Hygienic Design?
In the food and drink industry, as well as the chemical and pharmaceutical industry, or during the manufacture of electronic components, high demands are placed on hygiene. This applies to both employees as well as the machinery, equipment and accessories used.

Furthermore, the danger of food poisoning, contamination and product recall actions intensifies the pressure in this area. The necessity of reliable hygiene standards and rigorously implemented norms and guidelines is increasing in importance. This begins with the construction and planning of new equipment.

What is Hygienic Design?
The term “Hygienic Design” stands for the hygienic and cleaning-friendly construction of all machinery, equipment and components, deployed in hygiene-relevant areas of food and drink, pharmaceuticals, cosmetics and biotech production processes. In addition, Hygienic Design includes design principles for the prevention of constructional weak spots that could potentially increase hygiene related dangers or the risk of an infection, illness or disease transmission.

WERMA has the solution: The LED signal tower CleanSIGN
WERMA already has the appropriate solution to a challenge mechanical engineers and food manufacturers will have to face in the future: The new LED signal tower CleanSIGN

These signal towers were specially developed and constructed for use in food and hygiene areas. From the very start, the existing standards and directives (e.g. EHEDG documents 8 and 13, machinery directive 2006/42/EG) were rigorously implemented, and experts and specialists in the field of hygiene consulted (e.g. TU Munich, Frauenhofer Institut).

Wide range of sophisticated design features
The new CleanSIGN from WERMA is equipped with a series of sophisticated technical, constructional and design features which make a significant contribution to the safety of your products. For example, thanks to its compact construction it doesn’t have any uneven surfaces, grooves or joints where dirt could collect. This prevents impurities, significantly reducing the risk of contamination.

The chamfer of at least 3° as called for by the EHEDG has been rigorously applied in the design of the CleanSIGN: The 30° chamfer of the upper housing and bracket guarantees the rapid drainage of liquids, quick cleaning and easy inspection.

Cleaning-friendly design saves time and money
Thanks to the CleanSIGN’s cleaning-friendly design, cleaning times are significantly reduced and the simple and residue-free removal of dirt is guaranteed. In addition, savings are made in terms of energy and cleaning agent.

The Polyamide housing of the CleanSIGN is approved by the FDA (Food & Drug Administration) and is consequently food safe and resistant to cleaning and disinfectant agents. Furthermore, the tower’s connection element and mounting bracket are all of one piece. Thus additional joints where dirt could collect are avoided.

Simple mounting and long life duration
A so called “Pine Tree Clip” (quick-action fixture) enables quick and simple mounting. The attachment and connection of the tower is carried out from the rear. As a consequence the housing is completely closed and drill holes are avoided.

Furthermore, thanks to the LED technology employed, the light intensive CleanSIGN is maintenance free and equipped with a life duration of up to 50,000 hours. In addition, the integrated high volume buzzer ensures the signalling of all people outside the visible range.
