Nos paliers sont certifiés IP69K!

L’indice IP69K garantit en outre une étanchèité absolue même dans des applications qui sont soumises à des nettoyages frequents.

Initialement le test de IP69K a été développé pour les véhicules et spécifiquement pour les cas de nettoyage intensif comme les

Camions et Mélangeuses de ciment. Cependant l’indice IP69K est maintenant bien adapté par l’industrie alimentaire et embouteillage

Comme un indice de la résistance des produits contre les nettoyages frequents.

Dans le système de classification IEC 60529, l’indice IP6 se référe à la capacité du produit à resister la poussière.

L’indice 69K se référe à la capacité du produit à resister de vapeur d’eau à haute température / d’eau à haute pression.

Comment cette directive sera testée et évaluée normalement?

• Les produits certifiés IP69K doivent être capables de résister un nettoyage à haute pression ou un nettoyage vapeur.

• La procédure d’essai prescrit que la buse de pulvérisation sera alimentée à eau chaude de 80⁰ sous pression de 80-100 bar (1160-1450 psi) et un debit de 14-16 L/min.

• La buse de pulvérisation doit être maintenu 10-15 cm du dispositif soumis à l’essai à des angles de 0⁰, 30⁰, 60⁰ et 90⁰ gardant la position 30 secondes chaque fois.

• Le produit est centré sur un plateau tournant qui tourne toutes les 12 secondes.

Our bearing houses are USDA certified!

A high focus on hygienic design ensures that the bearing house can be cleaned behind and around the shaft and furthermore, NGI offers hygienic spacers to increase the distance to machines and equipment to over an inch as recommended by the USDA.

USDA Guidelines for the Sanitary Design and Fabrication of Dairy Processing Equipment: Point 23, Rotating shafts, page E 10 : ..."bearings shall be mounted to provide a minimum of 1 inch (25mm) exterior open space on the shaft between the mechanical seal for the bearing and the nearest part of the sanitary seal or the opening to the product contact area. The 1 inch (25mm) minimum space shall be open to the atmosphere and be easily accessible for inspection and cleaning."

Sum up of requriements for the USDA certification:

• 1 inch  (25mm) minimum space
• Material food approved
• Roughness maximum 1.6 Ra we are at 0.8 Ra
• Radii minimum 3.2 mm

3-A certified!

3-A SSI is a US based, non-profit organization dedicated to improving hygiene design in the food, beverage and pharmaceutical industries. The standards set are intended to ensure product quality and thus protect the health of the end user. The principles and certificates are therefore recognized by many countries and food manufacturers.

For the certification of hygienic parts, the evaluation is based on design features, so that, for example in a pipe, small angles or small radii should be avoided. This is to ensure the protection of consumer goods from contamination, a simple possibility for cleaning surfaces and easy disassembly for cleaning purposes.

The design specifications of the 3-A standards are very detailed and describe, for example, precisely the execution of radii and the required surface finish. If these specifications cannot be met, a 3-A certification of the product is not possible. 

All of our bearing houses and more of our certified hygienic levelling feet are 3-A certified.

EHEDG certified!

The EHEDG (European Hygienic Equipment Design Group) has been supporting hygiene measures during the production and packaging of food since 1989 and is a foundation of food-related organizations. The main task of EHEDG is to contribute to hygienic engineering and design in all areas of food production and thus to ensure the safe production of food. The EHEDG certifies hygienic components only if they satisfy theoretical approaches on the one hand and practical tests on the other. The EHEDG certificate is mainly recognized in Europe.

EHEDG is more general than 3-A in its formulations and describes the intended effect. If, for technical or functional reasons, the design, geometry and surface specifications cannot be met, the effectiveness of the chosen design must be proven through a cleaning test. If this test is passed successfully, this product will receive an EHEDG certificate, despite its design deviations.

 All of our bearing houses and more of our certified hygienic levelling feet are EHEDG certified.
