Certified cable glands for drinking water applications
With the Progress® aqua series, the KAISER Group is the first manufacturer to offer a cable gland which is certified for drinking water applications.
For reasons of health and hygiene, lawmakers have tightened the limits worldwide for the substances which drinking water is permitted to contain. In this case we are using lead as an example. Because of the risk to health which lead represents, on December 1, 2013, the limit value for lead was lowered to 10μg/l. Products which are used in the drinking water sector must comply with the requirements specified in the Foodstuffs and Commodities Act and also the Drinking Water Ordinance. The structural and technical condition of a plant and/or components used in the supply of drinking water must meet high quality standards. As a result of the guidelines in the DVGW (the German Technical and Scientific Association for Gas and Water), all fittings, devices, components and installation materials used in the distribution of water must consist of authorised materials. This is to ensure that the materials in the water supply do not release any undesirable substances into the drinking water or promote the growth of microorganisms.
All the materials in the Progress® aqua satisfy the requirements of KTW W270, and in this way they comply with the Drinking Water.
