Hygiene program officially EHEDG-certified

The EMKA quarter-turn and compression latch combine functionality with attractive design. Their hygienic application in sensitive environments – in the production of food, for example – was recently confirmed with the EHEDG certificate. The entire hygiene range is thus officially at the cutting edge of research and technology.


The hygiene requirements in the food and pharmaceutical industries are continually increasing – and with them the need for locking technology that meets these requirements and is certified in the best case. Therefore, EMKA has optimised its hygiene quarter turn lock according to the design specifications of the German Social Accident Insurance (DGUV) and the European Hygienic Engineering and Design Group (EHEDG) – and it did so with success. After the DGUV approval, EMKA has now received the corresponding EHEDG certification – for EL Class I AUX. This involves components in open processes that are cleaned with liquid without disassembly.

Outstanding competitive advantage

The core product of the EMKA hygiene program is the hygiene quarter turn. For example, it withstands the jet of a high-pressure cleaner and thus enables an efficient “Cleaning in Place”. It is completed by a unique compression latch and a hygiene key which completely eliminates metallic abrasion. The prerequisite for this is ­appropriately processed stainless steel components which EMKA develops in its Technology Centre, then manufactures itself and proceeds with comprehensive tests in its laboratory.

Customers increasingly requested the EHEDG certification. EMKA is thus the first supplier on the market to have this accreditation. This is a clear competitive advantage over many other commercially available closures for use in the food industry. The fact that EHEDG is in a worldwide exchange with American organisations such as NSF and 3-A concerning their specifications proves the hygienic and cleanable design and technology of EMKA locking mechanism technology also on an international level.

Background information

The European Hygienic Engineering and Design Group (EHEDG) is an association of equipment suppliers for food production, food processing companies, research institutes and public health facilities. Its purpose is to provide assistance to companies in implementing legal requirements and to enable a uniform EU-wide concept of action in compliance with international and national regulations.
