Rittal’s HD (Hygienic Design) series of enclosures have been awarded the ‘BG-PRÜFZERT’ test label by the German Health & Safety Association. The Hygienic Design Series is thus entitled to bear the label ‘Hygiene-tested’ as a testament to its use as a safe and salutary product. The test report describes how “The compact enclosure HD is suitable to accommodate electrical equipment in the food industry and is resistant to the cleaning and disinfectant agents typically used within the industry. It is also dust-proof and protects the installed components against strong jets of water (protection category IP66).”
The term ‘Hygienic Design’ embraces various measures to avoid design weakness which would otherwise be conducive to hygiene related risks. Rittal HD Enclosures have been designed to help eliminate any of these potential risks which could negatively impact on customer production. The construction material and silicone door-seals neither transfers nor exerts any negative influence of any kind. Surfaces are closed, smooth and easily cleanable with all undercuts, gaps, cracks, protruding edges and dead spaces eliminated. A 30° sloped overhanging roof allows easy cleaning and eliminates the hazard of containments pooling on the enclosure roof area. Adjustable levelling feet with internal threads make entrapments areas obsolete.
The statutory basis for the certification of ‘hygienic Design’ is the 9th Ordinance to the German Equipment and Product Safety Act which corresponds to the European Machinery Directive 98/37/EC (general demands pertaining to hygienic designs for food industry machinery are contained in Annex 1, subsection 2.1). Rittal HD Enclosures satisfies the closer definitions of these demands in accordance with DIN EN 1672-2:2005 and is classified under ‘food sector’.
